@@nunyabisnass1141 Yeah it's terrifyingly easy... I half accidentally made one out a car battery when I was 12, and it was a total miracle I didn't get hurt.
Filming idea: When you want to record a shot from downrange of an jet engine, use a mirror. This lets you keep the camera equipment out of the line of fire, while only risking a much cheaper mirror.
Pro tip, when you cut fuel in your engine, you’ll want to spin the compressor fan for a few moments after to run air through the engine. This helps it cool down and prolong the life span. Also if you want to film inside your engine and not burn the microphone, put a mirror in line with the exhaust port and angle it with a camera so you don’t burn the camera. The exhaust is pointed at a mirror
Another thing to add about the heat: Jets and turbines are cooled by the air in the engine. Increasing fuel without increasing airflow causes an increase in combustion temps. So if it's running too hot, increase airflow.
@@desertfresh3740 Huh! I haven't done the research on jet engines but for piston engines it's exactly the opposite. Its the fuel that cools the engine, not the air. In fact, too lean of a mixture can burn the electrodes right off a spark plug whereas too rich of a mixture cools the engine so much that you foul the plugs. Liquid cools much better than air which is why almost all other ICEs are liquid cooled rather than air cooled.
@@rudraigh "It's the fuel that cools the engine" Well... no. Only to an extent in some older engines and via a minor effect of evaporative cooling when the fuel is sprayed. The sheer majority of the cooling comes from coolant in the heat transfer system, hooked to a radiator. Adding more air won't really cool it because of the way that piston engines work but likewise, adding more fuel won't really cool it, either. You'll also result in a lot of unspent octane and messy emissions. (You're not exactly wrong but you're not entirely accurate.) That's not good for the engine. It works differently in a turbo as you aren't just compressing and combusting the air mixture but allowing it to pass over the fins and then expand, losing energy. Trying to do the same in a piston engine is just impossible. Hence why you need a secondary cooling system.
Video Idea: Make a thin tin sheeting metal plane that uses the spot welding and a rc prop or make your own engine for it, either way, I think it would be really cool to see something like that Love the content, even if it is only every couple weeks.

@@APLANEDUDEYT Thats fair I mean I don't own a printer either, BUT center of balance is really easy to do with a stick and some weights, but the stick in the middle and basically shift it a lil till it balances, an then you have center of gravity in the X direction, Y you do the same but Z is really hard. so you tend to not worry about it ALSO rc prop plane, would still be cool, and you dont have to worry about fuel
It looks like the engine would benefit from some sort of restriction at the exhaust as to increase the escaping gas velocity, assuming you can keep compression high enough at the intake. Some sort of a CD Nozzle should be pretty simple if you made out of a can or something, especially with that spot welder.
depends on how fast he exhaust gas are traveling sub-sonic and yes it can benefit from it. Supersonic and ya you'd decrease the gas velocity and lower efficiency.
@Eric C the effective momentum of the gas is Mass * Velocity^2. While increasing both is beneficial, increasing the velocity of the exiting gasses is much more beneficial than increasing the mass.
@Eric C I completely forgot about the mass flow rate of the system, but too be fair, if the exit speed of the exhaust for engines like this was inconsequential, then why do CD (or just converging) nozzles exist at all? As much as increasing the mass flow would also increase thrust, it would require a new compressor design, or stronger motors. Assuming that this isn’t cost effective for a moment, by optimising the velocity of the exhaust for the given mass flow rate, he would also in turn optimise the thrust output of the engine (as this increases the kinetic energy of the exhaust). As rocket engines are virtually the same as jet engines in this manner (they are both accelerating a gas to achieve a thrust), you can note that this isn’t just the effect of a turbine (as rocket engines do not have a turbine).
@@cailco100 You still use a nozzle (expansion nozzle) if its supersonic though... You can also tell just by looking at it that its not supersonic, but obviously it is just due to the extremely poor amount of thrust as well. Either way, nozzle is good both supersonic and subsonic.
Using sheetmetal and your spot welder now, you can try to implement a few different nozzles for this which would greatly affect the thrust products. 3D printed dies also can be used to bend sheetmetal. I guess it's time build a thrust set-up to characterize your homemade jet engines!
So many comments and then finally someone like you has a good idea, I was getting worried for a moment. I like the 3d printed stamping die idea, that's how to get consistent and easy controllable shapes, and if you burn one out you stamp another. Also makes it easy for others to replicate.
This isn't an ideal commitment for your channel it's a thanks for all tha hours you put into your work you have gotten me to use my 3D printers alot more instead of using them for paper weight so thanks keep up tha great work.
Video idea : using your welder and new engine to make a rc rocket, one that has controllable gas output! Maybe even controllable stages? Remeber! Tomatoes are disgusting 🍅💀
Adding an rc guidance system to a rocket could change it's classification to Missile. That can get you in a lot of trouble depending on where you are. But if it's not going up in the air then vectored thrust skateboard sounds cool
Quick note: Not all jet engines are the same. For example, the one you used in the beginning of your video is a high-bypass, turbofan engine. This means that the vast majority of thrust is NOT produced by the engine exhaust, but by the fan at the front of the engine.
So…next you need to add a bypass to it to allow most of the air taken in to bypass the combustion and mix back in afterwards. This will increase the thrust produced and is why turbo jet engines are designed so. Also lowers the noise
@@jeffstrongman7889 We typically only see afterburners on low bypass turbofans, turbojets and non-turbo types of jets. In most cases effectiveness will depend on how lean the main combustion is. In turbo type jets, lean mixes (like 4x more air as needed or even higher), to keep temps down, preventing damage to the in exhaust portions of the turbo mechanism. This leaves plenty of oxygen to add more fuel to and burn after those more fragile components. This inefficiently adds power. In a low bypass turbofan the bypass air can be mixed in with the hot flow, or not. There are real world examples of all three (hot only, cold only, the mix) being used for an afterburner. In this case, the simple jet doesn't have a turbo. It would likely be more power and fuel efficient to tune the main combustion closer to an ideal mix. I would also guess that the current build is running fuel rich. So there isn't any excess oxygen to use in a secondary burn, but that is just a guess.
@@ChucksSEADnDEAD That's fair. Your terse answer left some ambiguity in my mind, but I agree. What OP described was what most would classify as a turbo fan and they called it a turbo jet, but it would still be a sub class of turbo jet; if it had a turbo. I guess my problem, to me; for both, op and you; is that the video didn't have a turbo. So OP was wrong, but you didn't really correct it, but took it in another direction. Sorry for the rambling. My guess is that you know what you are writing about, but most, even most on a nerd channel like this, don't know that much about these terms.
@@bretfine688 thsts the point, its assumed he has limited space to work with. The same goes for ppl with enough like beyond the press channel. The stuff they do, the camera would have to be several hundred feet away and the camera could still get hit with shrapnel. So the solution is to put a camera behind a sheild, but focus it on a mirror with a line of sight to the event.
Have you ever thought about combining one of your rockets to an RC or even better you're own 3d car? Would be so cool to see this particular engine on one
Video Idea: Make some way to measure thrust output and put all the engines you've built over the years Head to Head to see how much your designs have improved!
Really good video, its amazing to see your progress from the earlier ones. Never giving up and open to make mistakes and learn from them. Spot welder almost stole the show, could have been a short on its own too ;) Parabéns!
8:49 Integza, those bubbling welds scared the crap out of me!!! I’m glad your safe mate!!! Video idea: put your jet engine inside an RC ME 263. Or make another engine and put both of them in an RC ME 262!!!
@@alexrobertson1472 yes, you are correct. Getting a permit to fly a jet powered aircraft is very difficult, getting a permit for a rocket powered craft all but impossible!!! Pick your battles carefully 😁
As someone who takes thermodynamics, I can say that you summed up the theory very well, would've appreciated to see an explanation of how expansion and compression is isentropic (meaning zero change in entropy, or just incredibly efficient), and heat addition and removal is constant pressure, and unfortunately it's hard to call this a jet engine, more or less a ducted fan with an overpowered afterburner. If you really want to make this a jet engine, you'll have to create the correct geometries so that the fuel and air can be ignited with a constant pressure, and the compressor, and more specifically your expansion process can follow a more isentropic curve. Also, your compressor isn't much of a compressor really, it just accelerates air and then heavily restricts flow, which just increases entropy really. If you want to make this more efficient, and potentially fly something, and believe me I've given this type of heat engine a lot of thought you need to do 4 things: - Compressor, make a 3d printed in your case, more preferably with titanium sls, or milled titanium, with multiple sets of blades (i'd recommend just copying blade geometry from existing turbojet designs) with an increasing inner diameters so that air is smoothly compressed which will greatly reduce your entropy generation, and achieve a much higher pressure. Also, make sure the tips of you blade do not exceed mach 0.9, I ran the calculations earlier and with a 10s 400kv motor, I think that made a blade diameter of like 150-200 mm, this of course would be the most efficient set up for isentropic expansion - heat addition, id recommend changing what type of fuel is injected and how it is, personally i'd recommend isopropyl,99.9 percent because it is cheap and easy to acquire but has a very large energy density, similar to kerosene, but burns at a lower temp. Youll need to create a way to push the isopropyl through small holes to atomize it, so it can combine perfectly with the air and allow for a constant pressure heat addition (which you'll also need to model geometry for), and increase efficiency - Expansion, this really is just all geometry based, and with your knowledge of rocket engines you should be able to figure out how to turn high pressure zero velocity air into low pressure high velocity air. Good luck I hope you revisit this, this is a very cool project and the engineering behind jet engines is very fascinating, also screw tomatoes also fun little bit of thermodynamics: Work (net) of a breyton cycle turbine is equal to Qout - work (compressor), what you're doing here is maximizing Qout by making all the compressor work be from the electric motor
Love your channel, I am glade your safe... drilling, cutting/welding on a "empty" fuel tank has its dangers even when there small (don't want you to lose an eye... that would suck, but would land you a few more views the wrong way.) The tank may appear to be empty... but it may have fuel residue and air.. possible an explosive mix... If you can fill it with water or an inert gas after it is empty then do the Hot work its an easy step that in future may save you from injury.
Idea: upgrade the engine by testing different fuels, higher pressures, and fuel outlet size. then make a rc wheel base to control where it goes! Would be kinda cool to see the acceleration over a distance larger than the floor.
Maybe get some metal shrouded hose and put it around the exhaust so it pre-heats the fuel since the butane tends to squirt out liquid and doesn't fully turn to gas in the tube.
Video idea: for a better way to power the jet. Add a nozzle to the end to control the jet blast better and make it more stream lined. Also you might want to make a bigger fuel cell and upgrade the intake jet so you have a better air flow. You are off to a great start and can achieve what ever you set your mind to. Congrats and have fun.
I can't believe how often I make my "oh dear god, how are you alive" face at your videos, I should be numb from I did a thing and such. Casually drilling into a brand-new can of butane is for those with no regard for their own life and I can't help but express it.
@@akshajajay5900 but he is still verry clearly using a fuel sorse for the combustion prosees or is fire made of 100% air last time i checked fire needs fuel oxygen and heat no? Sorry read your coment out of context but the idea can stillb used or developed
@@APLANEDUDEYT in a regular jet engine the combustion turns a turbine which in turn turns the compressor and the fan right? In this case the combustion is only producing the thrust and not connected to the compressor so if you want bypass you'd need to connect the front fan to the electric motor which would be energy take from the battery. Also remember that the bypass air isn't fed into the combustion chamber, that's why it's called bypass. It by passes the combustion chamber and flows around it.
@@akshajajay5900 i know but if you conect the rear blades of the jet engine to the electric motor you could efectivly use the batery to start the engine and save on batery power during jet operation and magnetic felds made by the electick moter can be used to break the speed of the moter or even increse throttling rates in theory annyway but the bigger qwestion would be what would the life expectancy be for the electric moter and the heat transfer sould alsow have an effect on the magnetic fields
Swap the electric motor for an impeller spun by the exhaust of secondary rocket engines to make the ultimate turbo-rocket engine! Maybe try running those CO2 canisters as the secondary rockets to prevent the turbine from instantly melting, while getting the main impeller to an insanely high speed.
8:53 That pop was dangerous! 11:32 The bowl popped because you only heated the bottom of it (the upper part, as it was standing with its opening facing downwards) and so it expanded unevenly.

After having seen many of your engines in action, the next logical step would be controlling the burn better. Up until now your fuel and air mixture has always been controlled analogically. It is time to bring your combustion to the digital era! I am thinking about the rocket version of EFI ;-)
I'm curious about the land speed record barrier. Most recent record holders are essentially jets without wings. The barrier comes from a quadratic drag coefficient. If you could demonstrate this it would be awesome. If you could overcome this it would be boss. If you could break the record it would be epic. I've always wondered if a laser leading the vehicle body might help. You might need a bigger skateboard though. If nothing else it would be another way of destroying tomatoes to add to your bat belt.
Do a episode where you make more homebrew equipment like the spot welder. I would love to see other tools like this featured! On a side note: Can you spot weld a tomato?
I have a few ideas on how to further improve the engine. If you look at your footage, you can see that the engine gets very hot, almost white hot. You could make a bypass fan on the front and a shroud to channel air over that hot area to help keep it cool. Also, you could re accelerate the air after it is ignited to make it go even faster. Just a few ideas to consider. Great video!
A bypass fan would require a turbine to drive the fan which was the one thing that he "simplified" out of his design by using an electric fan for the compressor. This is a hybrid jet engine (not even technically a turbo-jet, since no turbine), so he would have to add both a turbine and a fan, and at that point he may as well add a turbo-compressor...
@@dperreno I'm not saying a turbine has to drive it. Just make a driveshaft that can connect everything throughout the engine. Everything would still be driven by the electric motor, there would just be more fans.
Wow, this jet engine build was incredible! Your attention to detail and explanation of the process were top-notch. For your next video, how about exploring the creation of a small-scale rocket engine? It would be fascinating to see the differences in design and functionality compared to the jet engine. Keep up the amazing work!
I think a cool addition to this could be using a Pi Pico or other micro-controller to turn a single potentiometer into a dial for both the amount of propellent introduced, as well as the speed of the inducer.
For your next engine, you could use gears to turn the compressor and a 'ratchet' style clutch to turn the compressor. Then, you could run a center axle and an exhaust turbine! Once the turbine is turning at a greater RPM than the electric motor, it would turn the compressor instead thanks to the ratchet! Then you may have a fully self sustaining gas turbine! Would definitely need remote fuel cut off for safety though :D
You said you aren’t great with metalwork but that jet engine would make one hell of a forge burner. Might be a fun experiment to see how fast you could melt steel with that thing!
I would love to see you do a project involving ionic thrust, how quickly and efficiently you just made a mini spot welder gives me hope! Be careful though, electricity is very spicy.
"Although I struggle with English, I wanted to share an idea with you in this comment. Have you considered using nichrome wire to create a captivating jet engine effect? You could install a jet fan and arrange the nichrome wire in a circular pattern. By supplying electricity to the nichrome wire, the airflow from the jet fan would fall onto it, resulting in a realistic jet effect. Additionally, incorporating some fuel could potentially enhance the overall outcome. I hope you find this suggestion helpful and exciting. Keep up the great work on your channel!"
For being a Jet Turbine powered skateboard, it's amazingly slow. Lots of coloured flames, noise and heat, not much actual thrust though, amazingly so. It's a firework.
@@exo068 ya but he has already done hybrid rocket so i just got too confused and changed the comment only and ya he could do normal afterburner but solid just seems good for the video
Yeah, I don't think the combustion is doing anything at all. In a turbojet, combustion powers the turbine, which powers the compressor. That's the only job of combustion.... This has an electric compressor... So it shouldn't need any form of combustion.
Video Idea: try redesigning the compressor stage to resemble an automotive centrifugal supercharger. I've always wanted to see if a 3D printed compressor wheel could actually generate pressure, and since the intake would be perpendicular to the thrust all the forward thrust would be from the jet engine.
Loved the video as usual! I was just watching a throwback video of Mythbusters where they made a giant fireball using powdered coffee creamer. It turns out it is extremely flammable. My idea is that you try using powdered coffee creamer as a solid fuel? It will be messy but it may work well? Who knows...
Video Idea: it would be so cool to see that jet engine on a small boat! Since the friction slows the skate down so much, water might be the key to unleash the true power 👀 Imagine having it to rc stear too!
actually since the skate board is running on 8 individual bearings the friction should be lower that the drag created buy a body of a boat unless you can use hydro foils or even break the service tension on the water another way to achieve this would be do create a optimized low drag body for the boat fluid dynamics might help us understand the concept in depth
water actually causes alot of drag i think, i remember seeing a dude with an RC boat and he had some crazy ducted fan on it and it wasn't even that fast
I think that the thrust of the engine might actually help the boat to have less surface in contact as the speed increases! It's true that the the skate has bearings and all but its weight requires much more force to beat static friction and initiate the movement. Water's viscosity should be easier to beat, assuming that the dock is well designed. I though maybe of placing the butane can inside the boat so to help it sit higher on the surface but fluids mechanics is off my set of knowledge since I'm an informatics engineer :D
NICE !! This looks like an after burner vs a "jet" even though the combustion happens in a true combustion chamber. You could measure thrust from fan without AB and with to measure if AB gives more thrust a lot of times with EDF the flow of air is disrupted by gases instead of gasses adding to static thrust and efflux
4:485:05 you cant believe your PROFESSIONAL, store bought, spot welding machine is actually working?? . ya... who would have guessed that a dedicated spot welding machine would work!!?!?!?!?? its like saying "wow, my Lincoln electric MIG welder is really good at welding!!!"
so glad to see you posting more about this kind of stuff! i’ve been designing my own electric jet engine. i hope you wouldn’t mind if i use some of your ideas!
I can't wait to see what you can do when you get some more metalworking knowledge and tools. This is just the start and I'm going to be following you all the way 🔥
Video idea: mount a pipe with a bearing to something solid so that it can spin without flying away, attach different versions of your engines to it, and see how fast they can spin with maybe some comparisons to see which one spun the fastest.
Video idea: make a drone-type rocket. instead of a normal drone using four wings, you can use 4 small rockets to fly it. It would be pretty interesting to watch
You should try to make an underwater rocket engine. It would be a good next step to get to mars, considering there is no air in space. You could use electrolysis to get an oxygen and hydrogen mixture as fuel, or you could just buy an oxygen tank and continue to use butane.
An underwater rocket engine is actually the opposite to what is needed in space, as space is a vacuum (very little to no pressure), and water is under a lot of pressure (at least in earths oceans it is), so the exhaust needs to be at vastly different pressures (otherwise the exhaust might be pushed back into the rocket). Sounds like a cool idea though, if he were to combine it with some sort of supercavitating submarine maybe he could make a supersonic sub.
@@snortiblog good point, although I was thinking smaller scale where he just mounts the engine under water cause I imagine an entire sub would be too big of a project for one video. But with pressure in mind it would probably be best to keep the engine as close to the surface as possible while he is prototyping.
Video idea: using your new found spot welding skills go back and make an improved aerospike engine (because they always look awesome, and rockets are cool) Idea 2: spot welder tutorial? I think you would make a great tutorial and I want to make one myself now!
Next Crazy idea would be... To build a rocket that can carry payload and maybe with that we can place our own little satellite :P And hey I'm a software developer so please let me know if i can help with the satellite
Video idea: using your ceramic resin printer( for heat resistance), make a 1 cylinder engine and the regular 3D printers to make a carburetor to control the air-fuel mixture. You could probably even use the same propane cans from previous turbojet videos as the fuel!
@@Skiballer I wonder if he used a normal EDF, my little 70mm (below 3") EDF is rated for over 2 KG of thrust (so with 2 of them the skateboard would be accelerating as fast as if you dropped it off a building). I don't know if the flame would be helping much with that much flow rate, but it would be cool to see.
@@tianming. EDF is indeed "Electric Ducted Fan", yes, they are quite a bit more powerful since they are axial fans compared to inefficient centrifugal fan with afterburner (but he is just making it for fun, so its not a big deal that its super weak)
@@jakegarrett8109 The problem with EDF's is that they can't produce high pressure flow but high speed flow and that's why it wouldn't work with an EDF. He actually demonstrated this in a video called turbocharged pulse jet or something
Use a container and connect it with another container using a small host. In the second container put in another host that will be connected to the burna.
Great Stuff Integza. This is my first comment anywhere on RUclips. I like the way you think. Idea going forward is to try and make a drone using four of your jet engines. Also try changing the fuel to get more thrust. There are plenty of options to improve your jet engine.
Is it possible to build a jet engine in fluids other than air? Possibly an underwater jet engine with compressed oxygen for combustion support... but then again the water might be too dense for it to be effective... Also I really enjoyed the segment where you built your own spot welder, quite fascinating.
Make a wheelchair-robotic device for convalescents with AI that records the occupant’s mannerisms and consciousness so when the occupant travels into the great sonic winds of our universe, the recordings can be used as the “consciousness” in a humanoid that favors in likeness the recently deceased. This “humanoid” can be given to to family of the previously deceased as a “comfort animal.”
Idea: You should add gear ratios to get the pressure much much higher, there fore more thrust output. Eventually you should also build your own jet rc plane, see it in the air!
Just get a higher KV motor, no need for gears that are going to melt (fastest gearbox I have is 10,000 rpm, and you need ABS gears to keep it from melting in less than 2 seconds). You rewind the stator for higher KV and its going to be much more efficient as well. You can also just buy a motor rated for 100,000 rpm to begin with. I know my little 70mm edf is rated for over 2KG of thrust, so it should be accelerating that skateboard at half the acceleration of dropping it off a building. You could just use one of those, they also have a tremendous amount of static thrust (I use mine sometimes to clean out my car, its pretty dangerous on multiple fronts, haha!)
Video Idea: 1) Your could add a d nozzle that's made out of metal, This will increase the thrust and you could add this engine on a jet plane. 2) You could add a water cooling system to the end of the tube to make it less hotter. 3) You could use a more potent fuel and you could even add a oxidizer (this will make the engine extremally hot but check 2) 4) You should use more powerful motors and use a better battery with a higher voltage 5) You could add a moveable nozzle so you can direct the hot gasses towards where you want! These are my ideas, Please like this comment so Integza can see this!
Video Idea: You could make coil railgun. Put a sensor between every coil so the coil shuts down when the projectile exists the coil. You can reach extreme speeds with that.
BTW I love the genius of pushing flammable liquid or any gas for that matter through a chamber using an electric motor and hand made components. While you were making the pilot holes, I thought why not use a regular stove gas burner as the pilot but you would have to keep it vertical so the flame doesn't die out, and then I thought it could be done if you can place the gas burner then build a 90 degree bent metal tube where the flames would shout out from. Just an idea, so thought I'd share, being the least we can do for the entertaining video. Keep up the great job, hope to collab soon!

It looks like the engine would benefit from some sort of restriction at the exhaust as to increase the escaping gas velocity, assuming you can keep compression high enough at the intake. Some sort of a CD Nozzle should be pretty simple if you made out of a can or something, especially with that spot welder.
depends on how fast he exhaust gas are traveling sub-sonic and yes it can benefit from it. Supersonic and ya you'd decrease the gas velocity and lower efficiency.
@Eric C the effective momentum of the gas is Mass * Velocity^2. While increasing both is beneficial, increasing the velocity of the exiting gasses is much more beneficial than increasing the mass.
@Eric C I completely forgot about the mass flow rate of the system, but too be fair, if the exit speed of the exhaust for engines like this was inconsequential, then why do CD (or just converging) nozzles exist at all? As much as increasing the mass flow would also increase thrust, it would require a new compressor design, or stronger motors. Assuming that this isn’t cost effective for a moment, by optimising the velocity of the exhaust for the given mass flow rate, he would also in turn optimise the thrust output of the engine (as this increases the kinetic energy of the exhaust). As rocket engines are virtually the same as jet engines in this manner (they are both accelerating a gas to achieve a thrust), you can note that this isn’t just the effect of a turbine (as rocket engines do not have a turbine).
@@cailco100 You still use a nozzle (expansion nozzle) if its supersonic though... You can also tell just by looking at it that its not supersonic, but obviously it is just due to the extremely poor amount of thrust as well. Either way, nozzle is good both supersonic and subsonic.
Using sheetmetal and your spot welder now, you can try to implement a few different nozzles for this which would greatly affect the thrust products. 3D printed dies also can be used to bend sheetmetal.
I guess it's time build a thrust set-up to characterize your homemade jet engines!
Yes this one needs a million likes.
So many comments and then finally someone like you has a good idea, I was getting worried for a moment. I like the 3d printed stamping die idea, that's how to get consistent and easy controllable shapes, and if you burn one out you stamp another. Also makes it easy for others to replicate.
11:57 The effect how the engine nozzle shrinks due to the hot air is amazing!
Shouldn't it expand instead?
@@Zhak7 the hot air creates an optical lense making it look as if it shrunk.

Yessir
The engine is probably way too heavy to actually fly

Quick note: Not all jet engines are the same. For example, the one you used in the beginning of your video is a high-bypass, turbofan engine. This means that the vast majority of thrust is NOT produced by the engine exhaust, but by the fan at the front of the engine.
what the fuuu
So…next you need to add a bypass to it to allow most of the air taken in to bypass the combustion and mix back in afterwards. This will increase the thrust produced and is why turbo jet engines are designed so. Also lowers the noise
That's a turbofan.
Mate go youtube jet engines compared and explained.
@@jeffstrongman7889 We typically only see afterburners on low bypass turbofans, turbojets and non-turbo types of jets. In most cases effectiveness will depend on how lean the main combustion is. In turbo type jets, lean mixes (like 4x more air as needed or even higher), to keep temps down, preventing damage to the in exhaust portions of the turbo mechanism. This leaves plenty of oxygen to add more fuel to and burn after those more fragile components. This inefficiently adds power.
In a low bypass turbofan the bypass air can be mixed in with the hot flow, or not. There are real world examples of all three (hot only, cold only, the mix) being used for an afterburner.
In this case, the simple jet doesn't have a turbo. It would likely be more power and fuel efficient to tune the main combustion closer to an ideal mix. I would also guess that the current build is running fuel rich. So there isn't any excess oxygen to use in a secondary burn, but that is just a guess.
@@barongerhardt I was talking about OP's example, not the proposed experiment.
@@ChucksSEADnDEAD That's fair. Your terse answer left some ambiguity in my mind, but I agree. What OP described was what most would classify as a turbo fan and they called it a turbo jet, but it would still be a sub class of turbo jet; if it had a turbo.
I guess my problem, to me; for both, op and you; is that the video didn't have a turbo. So OP was wrong, but you didn't really correct it, but took it in another direction.
Sorry for the rambling. My guess is that you know what you are writing about, but most, even most on a nerd channel like this, don't know that much about these terms.
9:00. Next time use a mirror placed in front of the exhaust at an angle so you don't damage your equipment. Awesome video !
Lol, i just said the same thing.
yeah a 90° mirror shot is the classic, you can fix the rest in post if necessary
Or just a high zoom lens and move the camera a safe distance away
@@bretfine688 thsts the point, its assumed he has limited space to work with. The same goes for ppl with enough like beyond the press channel. The stuff they do, the camera would have to be several hundred feet away and the camera could still get hit with shrapnel. So the solution is to put a camera behind a sheild, but focus it on a mirror with a line of sight to the event.
Have you ever thought about combining one of your rockets to an RC or even better you're own 3d car? Would be so cool to see this particular engine on one

@@Reggy2000 i dont have issues with either, wherever you live doesnt sound very fun :(
Let's go! One of the few youtubers I get excited to see a notification from.
As someone who takes thermodynamics, I can say that you summed up the theory very well, would've appreciated to see an explanation of how expansion and compression is isentropic (meaning zero change in entropy, or just incredibly efficient), and heat addition and removal is constant pressure, and unfortunately it's hard to call this a jet engine, more or less a ducted fan with an overpowered afterburner. If you really want to make this a jet engine, you'll have to create the correct geometries so that the fuel and air can be ignited with a constant pressure, and the compressor, and more specifically your expansion process can follow a more isentropic curve. Also, your compressor isn't much of a compressor really, it just accelerates air and then heavily restricts flow, which just increases entropy really. If you want to make this more efficient, and potentially fly something, and believe me I've given this type of heat engine a lot of thought you need to do 4 things:
- Compressor, make a 3d printed in your case, more preferably with titanium sls, or milled titanium, with multiple sets of blades (i'd recommend just copying blade geometry from existing turbojet designs) with an increasing inner diameters so that air is smoothly compressed which will greatly reduce your entropy generation, and achieve a much higher pressure. Also, make sure the tips of you blade do not exceed mach 0.9, I ran the calculations earlier and with a 10s 400kv motor, I think that made a blade diameter of like 150-200 mm, this of course would be the most efficient set up for isentropic expansion
- heat addition, id recommend changing what type of fuel is injected and how it is, personally i'd recommend isopropyl,99.9 percent because it is cheap and easy to acquire but has a very large energy density, similar to kerosene, but burns at a lower temp. Youll need to create a way to push the isopropyl through small holes to atomize it, so it can combine perfectly with the air and allow for a constant pressure heat addition (which you'll also need to model geometry for), and increase efficiency
- Expansion, this really is just all geometry based, and with your knowledge of rocket engines you should be able to figure out how to turn high pressure zero velocity air into low pressure high velocity air.
Good luck I hope you revisit this, this is a very cool project and the engineering behind jet engines is very fascinating, also screw tomatoes
also fun little bit of thermodynamics: Work (net) of a breyton cycle turbine is equal to Qout - work (compressor), what you're doing here is maximizing Qout by making all the compressor work be from the electric motor
Hands down this is the best homemade jet engine I ever seen, keep going
Love your channel, I am glade your safe... drilling, cutting/welding on a "empty" fuel tank has its dangers even when there small (don't want you to lose an eye... that would suck, but would land you a few more views the wrong way.) The tank may appear to be empty... but it may have fuel residue and air.. possible an explosive mix... If you can fill it with water or an inert gas after it is empty then do the Hot work its an easy step that in future may save you from injury.
Idea: upgrade the engine by testing different fuels, higher pressures, and fuel outlet size. then make a rc wheel base to control where it goes! Would be kinda cool to see the acceleration over a distance larger than the floor.
Maybe get some metal shrouded hose and put it around the exhaust so it pre-heats the fuel since the butane tends to squirt out liquid and doesn't fully turn to gas in the tube.
Video idea: for a better way to power the jet. Add a nozzle to the end to control the jet blast better and make it more stream lined. Also you might want to make a bigger fuel cell and upgrade the intake jet so you have a better air flow. You are off to a great start and can achieve what ever you set your mind to. Congrats and have fun.
I can't believe how often I make my "oh dear god, how are you alive" face at your videos, I should be numb from I did a thing and such. Casually drilling into a brand-new can of butane is for those with no regard for their own life and I can't help but express it.
The sound of that little engine is insane! Also the sound when it ignites! Nicely done sir!
I can't help but feel like a nozzle would make a world of difference to the thrust output
What about a bypass turbine that could increase trust output and efficiency
@@APLANEDUDEYT He's not using the energy produced in combustion to spin the compressor so the bypass created would be energy taken from the battery.
@@akshajajay5900 but he is still verry clearly using a fuel sorse for the combustion prosees or is fire made of 100% air last time i checked fire needs fuel oxygen and heat no? Sorry read your coment out of context but the idea can stillb used or developed
@@APLANEDUDEYT in a regular jet engine the combustion turns a turbine which in turn turns the compressor and the fan right? In this case the combustion is only producing the thrust and not connected to the compressor so if you want bypass you'd need to connect the front fan to the electric motor which would be energy take from the battery. Also remember that the bypass air isn't fed into the combustion chamber, that's why it's called bypass. It by passes the combustion chamber and flows around it.
@@akshajajay5900 i know but if you conect the rear blades of the jet engine to the electric motor you could efectivly use the batery to start the engine and save on batery power during jet operation and magnetic felds made by the electick moter can be used to break the speed of the moter or even increse throttling rates in theory annyway but the bigger qwestion would be what would the life expectancy be for the electric moter and the heat transfer sould alsow have an effect on the magnetic fields
Swap the electric motor for an impeller spun by the exhaust of secondary rocket engines to make the ultimate turbo-rocket engine! Maybe try running those CO2 canisters as the secondary rockets to prevent the turbine from instantly melting, while getting the main impeller to an insanely high speed.

8:53 That pop was dangerous!
11:32 The bowl popped because you only heated the bottom of it (the upper part, as it was standing with its opening facing downwards) and so it expanded unevenly. That put strain on the glass. You may know, glass really doesn't like that. So it popped while settling while cooling down again.

After having seen many of your engines in action, the next logical step would be controlling the burn better. Up until now your fuel and air mixture has always been controlled analogically. It is time to bring your combustion to the digital era! I am thinking about the rocket version of EFI ;-)
I absolutely adore the shear insanity it takes to innovate solutions on the fly like this. Never change.
I'm curious about the land speed record barrier. Most recent record holders are essentially jets without wings. The barrier comes from a quadratic drag coefficient. If you could demonstrate this it would be awesome. If you could overcome this it would be boss. If you could break the record it would be epic. I've always wondered if a laser leading the vehicle body might help. You might need a bigger skateboard though. If nothing else it would be another way of destroying tomatoes to add to your bat belt.
Do a episode where you make more homebrew equipment like the spot welder. I would love to see other tools like this featured! On a side note: Can you spot weld a tomato?
Integza please create Steam fires underwater jet engine
jet engines need air. the thing that would work here, is a rocket engine
I have a few ideas on how to further improve the engine. If you look at your footage, you can see that the engine gets very hot, almost white hot. You could make a bypass fan on the front and a shroud to channel air over that hot area to help keep it cool. Also, you could re accelerate the air after it is ignited to make it go even faster. Just a few ideas to consider. Great video!
A bypass fan would require a turbine to drive the fan which was the one thing that he "simplified" out of his design by using an electric fan for the compressor. This is a hybrid jet engine (not even technically a turbo-jet, since no turbine), so he would have to add both a turbine and a fan, and at that point he may as well add a turbo-compressor...
@@dperreno I'm not saying a turbine has to drive it. Just make a driveshaft that can connect everything throughout the engine. Everything would still be driven by the electric motor, there would just be more fans.
Wow, this jet engine build was incredible! Your attention to detail and explanation of the process were top-notch. For your next video, how about exploring the creation of a small-scale rocket engine? It would be fascinating to see the differences in design and functionality compared to the jet engine. Keep up the amazing work!
I think a cool addition to this could be using a Pi Pico or other micro-controller to turn a single potentiometer into a dial for both the amount of propellent introduced, as well as the speed of the inducer.
For your next engine, you could use gears to turn the compressor and a 'ratchet' style clutch to turn the compressor. Then, you could run a center axle and an exhaust turbine! Once the turbine is turning at a greater RPM than the electric motor, it would turn the compressor instead thanks to the ratchet! Then you may have a fully self sustaining gas turbine! Would definitely need remote fuel cut off for safety though :D
I would have burned myself so many times doing this hehehehe
You said you aren’t great with metalwork but that jet engine would make one hell of a forge burner. Might be a fun experiment to see how fast you could melt steel with that thing!
Amazing as always. Your spot welder is really impressive!
Yes, that's cool and everything, but where is the mustache?! 😱
Finally!
I would love to see you do a project involving ionic thrust, how quickly and efficiently you just made a mini spot welder gives me hope! Be careful though, electricity is very spicy.
"Although I struggle with English, I wanted to share an idea with you in this comment. Have you considered using nichrome wire to create a captivating jet engine effect? You could install a jet fan and arrange the nichrome wire in a circular pattern. By supplying electricity to the nichrome wire, the airflow from the jet fan would fall onto it, resulting in a realistic jet effect. Additionally, incorporating some fuel could potentially enhance the overall outcome. I hope you find this suggestion helpful and exciting. Keep up the great work on your channel!"
My idea for a video: Put this kind of Jet engine on a rc plane. Maybe you could 3D print it or make it out of foam! I would love to see it!
That would be great
make an afterburner for the jet engine, that would be sick.
Isn't it already more of an afterburner than a full jet engine? Afterburners just dump extra fuel into the engine
@@APMtube9000 that's what I was trying to say but you said it better
For being a Jet Turbine powered skateboard, it's amazingly slow. Lots of coloured flames, noise and heat, not much actual thrust though, amazingly so. It's a firework.
Nice work! I think the engine needs more compression, that flame was very big 😊
Video idea: you could try making a d nozzle to use thrust vectoring on an rc plane like on real planes !
Video idea: You should make a rocket engine using items from around the house. May I suggest hairsprays fuel.
Great idea
Would be very interesting!
he is doing this in the video
@@giorgio5598 not really
Lets get you that 3d printer lol
I think you should make custom fuel for the turbo jet and see which mixture produces the most thrust for the jet
He could also do a normal afterburner.
@@exo068 ya but he has already done hybrid rocket so i just got too confused and changed the comment only
and ya he could do normal afterburner but solid just seems good for the video
This type of jet does not slow the exhaust down in order to run the compressor, absolutely wonderful design!!!
You should also try just the fan. So you can see how much the combustion adds tho the thrust
Or attach the same motor to one of the wheels directly instead of a fan and compare the acceleration without the rocket..
Yeah, I don't think the combustion is doing anything at all. In a turbojet, combustion powers the turbine, which powers the compressor. That's the only job of combustion.... This has an electric compressor... So it shouldn't need any form of combustion.
I think the coolest thing about this is the sound. It sounds amazing
Video Idea: try redesigning the compressor stage to resemble an automotive centrifugal supercharger. I've always wanted to see if a 3D printed compressor wheel could actually generate pressure, and since the intake would be perpendicular to the thrust all the forward thrust would be from the jet engine.
The combustion chamber u made was pretty legit 👍

I was just watching a throwback video of Mythbusters where they made a giant fireball using powdered coffee creamer. It turns out it is extremely flammable. My idea is that you try using powdered coffee creamer as a solid fuel? It will be messy but it may work well? Who knows...
Video Idea: it would be so cool to see that jet engine on a small boat! Since the friction slows the skate down so much, water might be the key to unleash the true power 👀
Imagine having it to rc stear too!
actually since the skate board is running on 8 individual bearings the friction should be lower that the drag created buy a body of a boat unless you can use hydro foils or even break the service tension on the water another way to achieve this would be do create a optimized low drag body for the boat fluid dynamics might help us understand the concept in depth
water actually causes alot of drag i think, i remember seeing a dude with an RC boat and he had some crazy ducted fan on it and it wasn't even that fast
i thought the same thing
I think that the thrust of the engine might actually help the boat to have less surface in contact as the speed increases!
It's true that the the skate has bearings and all but its weight requires much more force to beat static friction and initiate the movement.
Water's viscosity should be easier to beat, assuming that the dock is well designed. I though maybe of placing the butane can inside the boat so to help it sit higher on the surface but fluids mechanics is off my set of knowledge since I'm an informatics engineer :D
NICE !! This looks like an after burner vs a "jet" even though the combustion happens in a true combustion chamber. You could measure thrust from fan without AB and with to measure if AB gives more thrust a lot of times with EDF the flow of air is disrupted by gases instead of gasses adding to static thrust and efflux
My thoughts exactly 👍
4:48 5:05 you cant believe your PROFESSIONAL, store bought, spot welding machine is actually working??

Screw that, make a rocket.
I can't wait to see what you can do when you get some more metalworking knowledge and tools. This is just the start and I'm going to be following you all the way 🔥
Video idea: mount a pipe with a bearing to something solid so that it can spin without flying away, attach different versions of your engines to it, and see how fast they can spin with maybe some comparisons to see which one spun the fastest.
This is great ,I'm getting my garage cleared and painted white I'll get the door fixed and start making things ,great ,thanks buddy
Video idea: make a drone-type rocket. instead of a normal drone using four wings, you can use 4 small rockets to fly it. It would be pretty interesting to watch
You should try to make an underwater rocket engine. It would be a good next step to get to mars, considering there is no air in space. You could use electrolysis to get an oxygen and hydrogen mixture as fuel, or you could just buy an oxygen tank and continue to use butane.
An underwater rocket engine is actually the opposite to what is needed in space, as space is a vacuum (very little to no pressure), and water is under a lot of pressure (at least in earths oceans it is), so the exhaust needs to be at vastly different pressures (otherwise the exhaust might be pushed back into the rocket). Sounds like a cool idea though, if he were to combine it with some sort of supercavitating submarine maybe he could make a supersonic sub.
@@snortiblog good point, although I was thinking smaller scale where he just mounts the engine under water cause I imagine an entire sub would be too big of a project for one video. But with pressure in mind it would probably be best to keep the engine as close to the surface as possible while he is prototyping.
Video idea: using your new found spot welding skills go back and make an improved aerospike engine (because they always look awesome, and rockets are cool)
Idea 2: spot welder tutorial? I think you would make a great tutorial and I want to make one myself now!
If you had a simple ramp you could approximately measure thrust using the weight.
The work this man does is next level.

Integza make a sugar rocket using carbon so it flies well

I was really wondering how much thrust it was producing with just the electric fan. How much of a difference does the rocket part actually make?
The fan probably contributed pretty much none of the thrust
@@Skiballer I wonder if he used a normal EDF, my little 70mm (below 3") EDF is rated for over 2 KG of thrust (so with 2 of them the skateboard would be accelerating as fast as if you dropped it off a building). I don't know if the flame would be helping much with that much flow rate, but it would be cool to see.
wasn't edf just an impeller
@@tianming. EDF is indeed "Electric Ducted Fan", yes, they are quite a bit more powerful since they are axial fans compared to inefficient centrifugal fan with afterburner (but he is just making it for fun, so its not a big deal that its super weak)
@@jakegarrett8109 The problem with EDF's is that they can't produce high pressure flow but high speed flow and that's why it wouldn't work with an EDF. He actually demonstrated this in a video called turbocharged pulse jet or something
Use a container and connect it with another container using a small host. In the second container put in another host that will be connected to the burna.
Great Stuff Integza. This is my first comment anywhere on RUclips. I like the way you think. Idea going forward is to try and make a drone using four of your jet engines. Also try changing the fuel to get more thrust. There are plenty of options to improve your jet engine.
Video idea: you can try to vector control your engine with a tone of different technology it could be so cool like tvc nozzle and all those stuff
Is it possible to build a jet engine in fluids other than air? Possibly an underwater jet engine with compressed oxygen for combustion support... but then again the water might be too dense for it to be effective... Also I really enjoyed the segment where you built your own spot welder, quite fascinating.
Make a wheelchair-robotic device for convalescents with AI that records the occupant’s mannerisms and consciousness so when the occupant travels into the great sonic winds of our universe, the recordings can be used as the “consciousness” in a humanoid that favors in likeness the recently deceased. This “humanoid” can be given to to family of the previously deceased as a “comfort animal.”
Idea: You should add gear ratios to get the pressure much much higher, there fore more thrust output. Eventually you should also build your own jet rc plane, see it in the air!
Just get a higher KV motor, no need for gears that are going to melt (fastest gearbox I have is 10,000 rpm, and you need ABS gears to keep it from melting in less than 2 seconds). You rewind the stator for higher KV and its going to be much more efficient as well. You can also just buy a motor rated for 100,000 rpm to begin with.
I know my little 70mm edf is rated for over 2KG of thrust, so it should be accelerating that skateboard at half the acceleration of dropping it off a building. You could just use one of those, they also have a tremendous amount of static thrust (I use mine sometimes to clean out my car, its pretty dangerous on multiple fronts, haha!)
Video Idea:
1) Your could add a d nozzle that's made out of metal, This will increase the thrust and you could add this engine on a jet plane.
2) You could add a water cooling system to the end of the tube to make it less hotter.
3) You could use a more potent fuel and you could even add a oxidizer (this will make the engine extremally hot but check 2)
4) You should use more powerful motors and use a better battery with a higher voltage
5) You could add a moveable nozzle so you can direct the hot gasses towards where you want!
These are my ideas, Please like this comment so Integza can see this!
well ive found my next project
he should re design it because it does not produce any useful thrust
@@makantahi3731 True, I also think he should change the body shape as it decreases the thrust
Video Idea: You could make coil railgun. Put a sensor between every coil so the coil shuts down when the projectile exists the coil. You can reach extreme speeds with that.
BTW I love the genius of pushing flammable liquid or any gas for that matter through a chamber using an electric motor and hand made components. While you were making the pilot holes, I thought why not use a regular stove gas burner as the pilot but you would have to keep it vertical so the flame doesn't die out, and then I thought it could be done if you can place the gas burner then build a 90 degree bent metal tube where the flames would shout out from. Just an idea, so thought I'd share, being the least we can do for the entertaining video. Keep up the great job, hope to collab soon!
