Measured fuel injection system, fanspeed control with power meter for monitoring draw, add more holes into the endpoint of the injection system for better fuel atomization. Just a few ideas that come to mind, thank you for your amazing videos! Educational and fun!
He could also add another tube that's capped or a complete circle loop with holes drilled in it that's half the diameter of the acrylic tube. Place it in the middle of the flame dispersal zone, and it'll act as an afterburner.
Hi! I think the thrust could be improved by adding an extra fuel injector towards the end of the tube, this should inject most of the fuel. But for the second injector to work you need a smaller flame shielded by the motor, this way the air temperature could be increased to help the second combustion. In addition to this reducing the outlet diameter of the engine should help increase the pressure in the combustion chamber further improving the combustion efficiency. Furthermore using an EDF like this: "12V 9000KV Inrunner Brushless Motor High Speed Jetfan EDF" with a proper metal combustion chamber and an exhaust diameter that allows the fan to build up some pressure in the combustion chamber. This way you use the fan as the jet engine's compressor, instead of just adding an afterburner that has horrible efficiency. Imagine it like a low bypass turbojet where the compressor is powered by electricity instead of a turbine wheel. By the way, tomatoes are disgusting I love your videos because you build pretty impressive stuff with tools that almost anyone can get.
@@猫の仕事部屋Yeah, but an afterburner burns fuel at ambient pressure and it doesn't run on a stoichiometric air-fuel ratio, that is the reason why they have terrible fuel efficiency. The reason why fighter jets have to run afterburners is, that the heat of the exhaust would melt the turbine blades if they were to inject that fuel into the main combustion chamber. And since Integza’s engine doesn’t rely on a turbine to run the compressor (the fan) it could benefit from using compressed air to burn fuel. Sadly I can't test my theory, because I don’t have the necessary funding and equipment.
This but with a turbine instead so the air is compressed. You also want to compress the fuel btw. If i'm correct real powerful jet engines do this. Last the color of the outlet 'flames' shows how good the combustion really is so we don't want no yellow flames.
@@Madrrrrrrrrrrr Yes, you can use compressed butane (1-2 bar or less) or a liquid fuel system but that requires an injector that atomizes the fuel really well. I think the biggest issue with this design is finding a fan with a high enough flow rate and static pressure. Do you have any ideas about what kind of fan/compressor could be used?
Reupload? Rewatching! I’ve been watching since you were firing rockets in a wooden attic. I’m constantly amazed your channel is allowed to exist. Keep up the the work! Science!
The venturi effect works like magic to not only reduce pressure and atomize liquid fuel into a vapor, but also to slow gas mixtures for combustion. What you have there is closer to a jet engine which uses a similar principal, except there is a fan or impeller as a compressor in the inlet, connected via shaft to anouther fan or impeller on the exhaust end, with a venturi burn chamber in between. No need for electric motor post initial spool up.
It's very simple just concentrate all the air flowing and make the exit tighter You can also make the tubing for the rule attached to the outer layer so it would not hinder it's performance

The simplest way I can think of that will probably allow you to use more of the air for combustion is to basically use an afterburner, which just injects more fuel in the hot, lean air after the engine core. But, and here's the part that makes this super simple, is that you inject the fuel in at the edges at the intake. The fuel would have time to mix and atomize with the incoming air, and the existing 'jet core' would act as an ignition source. Real afterburners aren't efficient because the core gains efficiency from igniting the fuel/air mixture under compression while the afterburner uses uncompressed mixture to burn, but you're using uncompressed fuel/air mix the whole way through so this is entirely bonus thrust for this design.
Essentially just add more injection points to spread out the fuel during combustion. I think the hard part is going to be protecting the acrylic though.
First don't use acrylic second make a ring of a aluminium pipe with some hole for injecting fuel. And why not use a bldc motor which automatically gets lower when fuel less burns? and tries to use more flammable Gus with high pressure..@@Antal-te6rj
I wonder if adding the fuel before the fan would help, All tho I wonder if the diluted fuel would be difficult to ignite and if it would melt the and bun out the fan.
13:30 if you had a pressurized air tube around the entire acrylic tube that allow more airflow in so then the engine could have. More or easier combustion. Plus thrust.
Use Dyson tech, Put additional holes on the side of the acrylic to let in more air. The fast airflow will suck in additional air into the pipe. If you want better mix add additional length to the pipe and put a nice cone shape funnel at the end of the tube/pipe.
You are confusing detonation with expansion. Jet engines burn fuel then use the heat to expand air. You DON'T want a 100% air combustion. You want the least amount of fuel burnt to produce the most amount of thrust/work. You do this by creating a "flame can" to protect the fire from being blown out with inlet holes that allow for precise and controlled mixture of cool air to mix with hot air as it exits to the exhaust turbine. There are many books on turbojet operation that explain this process. Best of luck.
its not a turbojet its an electric fan with something akin to an afterburner there isnt any turbine which is part of why its not going to get high thrust and compression ratios its basically just a butane torch lighter at this point
My best idea for improving the design is a better air to fuel mix. Currently you have a lot of air and not so much fuel. If you make a spiral coil with the copper tube, you can make a bunch of tiny holes along it's length in order to pump more fuel into the stream, you can try both a simple spiral with a crimped/soldered end tube, or one with both ends of the tube getting fuel pumped in, and the spiral meets at the center, where there would be a the end point/mid point of the tubing. This design probably needs a pilot flame behind it, at least for ignition, but might need it in order to heat the fuel up before injection/ejection.
I would be more worried about getting more air into the middle of the flow first. Then add fuel. But I do agree that more fuel equals more flame. I'm just thinking of getting a more complete burn within the tube.
Hey Integza , for improved propulsion, it's recommended to channel the air flow through the center while directing the fuel to the outer side. Utilizing a technique similar to the porous knife demonstrated in your video can facilitate better mixing of the fuel and air, enhancing overall efficiency and performance. And you forgot to destroy a tomato in this video.
@Integza, remove your heart from this comment, it's a bot comment made to link to *ahem* certain websites. I'm reporting it. Try to look at who you give hearts next time!
I followed your RDE video here. Here’s my suggestion: An automotive spark plug enters the tube from the side. Covering half of the sparky part is a partial cover which shields the spark from the fuel-air flow stream and initiates a radial rotation of the flame front. Upstream of the spark plug are two wire screens in parallel, which form a flame suppressor. Also upstream is a Tesla check valve, to minimize the pressure waves going to your fresh air pressure source: a shop vac. Fuel and air are mixed after pressurizing. Fuel, air, spark, rotational flame front. Adjust the exhaust tube length and spark frequency to get the right pressure for detonation. Voila!
the text is partly from the translator because I don't know some terms, I'm from Poland and I don't want to make a mistake and embarrass myself :D my idea is to make a similar design to military jets, use multiple fuel injectors in a cylindrical shape as you did in previous videos, for example "I built an Electric Jet Engine from scratch" 6:07. Then the fuel you would use if you wanted it to be heated would have to use a separate heat source oooor, which is a better idea in my opinion, change the casing to a metal one, unfortunately it will no longer be ZE FLAMES but if you want to use as much air as possible for combustion you will not be able to use the outer layer air as an insulator. Returning to the fuel line, you will be able to wrap it around the exhaust to, firstly, heat the fuel before ignition, and secondly, it will act as a small radiator, so it will slightly reduce the temperature of the casing, just something similar like the raptor engines in SpaceX rockets are cooled. Finally, I will just add a few comments so that you remember, firstly, when you record, remember not to put it too close to the camera as you once melted it, the same applies to the wind meter, and secondly, remember about the final test with the tomato. Even if I don't win, I hope I helped
and I remembered it, but it's probably too complicated for such a small scale, you can use 2 or more propellers to increase the air pressure and speed, like in turboprop engines
Increase the power of this by Creating a nozzle which thins Towards the end of the ignition chamber and then widens out again this will give you more compressed air just before the already ignited Fuel and air this means all the fuel and air expands together giving the engine more draught and more power.
@Integza, All you need to do is put a nosle on the exit/front of the combustion chamber like they had in the original video. If ypou narow the escape of the flame it will burn up more oxigen.
Integza you dangerous madman, you made the dryer get hotter, and didnt change the plastic to something more fire resistant, you are creating a massive fire hazard.
Just a heads up. Propane tends to be used as an aerosol propellant. It is possible that the propane in the breaks cleaner is being ignited. If this is the case, the fuel-to-air mixture needs to be between 2.15% and 9.6%
@@Franklin_Johanessan sometimes youtubers have to re-upload and cut some of the content due to youtube's "policies", copyright and sometimes the yellow monetization, it's really complicated
Hey Integza! You need a flame shroud or tube. What you are building is a Turboramjet or Air turborocket. It is the very simple version of a jet engine. Also a company is using it for a SSTO type rocket, using the fanjet portion in atmosphere then using like a rocket out of the atmosphere. So you need a flame shroud to keep the flame protected and allow it to heat the air completely. Its close to what you did, just a tube with lots of holes in it. Longer tube, more holes, make power!! Good luck! Feel free to reach out and geek.
Hi integza, I'm a Brazilian fan and I always wanted to see you building a remote control plane. I have a simple but interesting idea, so you would build with foam, Balsa wood and 3D printed parts . With this you could insert a compressed air engine. I know it can be very complex but it would be very interesting to do this project. (sorry for my English) PS: the engine could be based on a tesla turbine.
Alright integza , here is my idea: your model reminded me of an afterburner rather than the turbo jet it self, so I come up with 3 main changes. 1st scratch the combustion tube and coil the copper fuel tube over the nicrom wire and drill tiny holes at the end of the copper tubing, Thus the fuel will get heaten up beforehand and we can let all the fuel get contact with the nicrom wire. 2nd change the fan desing on the electric motor and make it like a multi stage fan and add a 3d printed or acrylic funnel like desing behind of it, this way, I believe, we can divide the incoming air into 2 sections with one being in the free flow state to keep the system cool and rest of it to mix more oxygen into fuel. 3rd change is not even a change but more like keeping the first desing by keep adding fuel in the front so we can get a afterburner effect. Some extras might be adding a selenoid constraption with potantiometers to control the fuel flow and adding a exhaust cone to end. These are what I have come up with so far, I can try to draw a detailed model to explain all beter maybe. And it might be good idea to add that I have no experience with jet engines. Also I have used a lot of inspration from your older electric jet engine project and the EDF after burner one.
I think a suction would work, or something like what the SR71 blackbird uses. Or you could use a longer version of what you have now, pulling as much air as possible in and useing more time to accelerate it.
The hair dryer you were looking at was an older model where the heating element is in the back similar to a room floor heater. Electric element but it was in the rear and the blowers also sucking from the heat and pushing it forward
Id reccommend a clonical MIG shroud, its designed to take the maximum output of gas and force it into a tube shape. It could help you achive a better gas flow rate as they often run at 11 liters per minute
To improve the hairdryer engine, couldn't you use the same style as a typical jet engine? Multiple fans - 1 to bring air in and one to compress it? maybe using a belt fan/larger size for the first and a small server room fan for compression?
Better yet, use the fan systems from two different hair driers. You use the normal bladed fan to accelerate incoming air which is then fed to an impeller system to compress the high-speed air to a greater degree.
1. We can use a contra rotating propeller to produce more thrust and hence more power.(The propeller can have max. 4 blades and not more than that.) But it comes with its own issues. When thrust increases by so much there is a slight chance that the ignition might not work properly and might fail. Hence the best solution that I can think of is that you can improve the covering of the ignition and design it like a missile but with a small perforation at the initiation. This way we can produce more thrust without compromising the issue of ignition. 2. An afterburner might work as well. An afterburner means more space and hece some changes to the design. First issue is the issue of the fuel rail coming in between the ignition and the afterburner. For this you can just coil the tube on the outside of the ignition and then inject. Another sub tube will inject the fuel into the afterburner.This way a lot of more thrust will be generated and fuel efficiency will be maintained. 3. The exhaust diameter must be of a bit smaller so that the pressure is created inside the chamber and this way it theoretically could produce so much thrust that it should be able to propel your skateboard :) And yes, Tomatoes are bad!!! We hate tomatoes!!!!!
Great video, although at the moment its a glorified blowtorch and not a jet engine, but still, good job. A tip I have is that you could just use a convergent pathway right after the fan and get a more powerful motor. As you likely know, that's how air is compressed in the compressor in gas turbine engines, and I'm sure it'll work for you as I know a thing or two about gas turbines and worked on them in the past. Speaking about Gas Turbines, atlhough it would be a much more time-intensive project and would require some metal-working skills it would be great if you could do a version 2 of your Turbojet Engine on a larger scale and using less 3D-printed parts which are highly susceptible to melting. I'd gladly wait for a while for that.
Jet engine project Well I watched an 8 minute video on how a turbo fan jet engibe works. Got the general idea of it. Took a can, PVC pipe as the inner co pressor that directs airflow towards the rear inlet, placed a cap on the end and put aluminum flaps in that area for direction of airflow. The cap holds the fuel. I ignite it and ram air fliw into the front of the jet. Tje airfliw passes through the PVC tubing for airflow direction and over the ignited fuel whixh produces thrust and afterburn. At this point in time I didn't have a turbine/fan so I simulated the turbine with a hair dryer as air flow. Now, I am currently working on an electrect ducted fan blade for a bigger turbine system.
regarding this video, I would suggest using a car vacuum cleaner, but used upside down, that is, on the exhaust, it has more force.. and if you also printed some static steering paddles, it would be amazing because it wouldn't give the flame back...
I can’t use the 3D model but I would suggest that thru the acrylic tube make small holes and insert injection like needles. Thru these needles use O2 gas just before the ignition and use a gauge on O2 cylinder to control the thrust. This basically be like 4 holes on the tube and some needles with O2 flowing in them and solving the problem without having any issues with the fan speed. I may be wrong but you can try on a 3D model.
i am no expert but i have an idea, so maybe u can put the nichrome wires around the injector and put bunch of holes to the injection tube, that way it will have more time getting oxygen without fighting the wind. and also putting a narrow nozzle in the tip will make a more controlable and stronger thrust i guess.
Hey Integza, I had an idea for a future video, why don't you revisit your rotating detonation engine, and try making it using NASA's 3d printable GRCop-42 Copper that they used to test the RDE
Hello! As stated in the first video upload, I believe the issue with the « new » air drier is the air to fuel ratio (AFR) is out of the flammability range for the brake cleaner. Thus the brake cleaner may just dilute in the air without burning. If this theory is true, then decreasing the AFR by injecting brake cleaner by 2 bottles may be the solution to get a bigger flame than the current one with the broken air drier. Then, looking at the custom solution, adding a second injection ring along the internal wall of the tube, about 10cm behind the combustion chamber could be enough to use all the air available in the tube. Combustion would be launched by already burning gaz from the inner flame. This would work as a post combustion on a jet fighter aircraft. Hope this helps!
The obvious thing to do is to channel some of that air into the combustion chamber. Just some small tubes (with a flair at the end) directing some air into the combustion chamber. Some tweaking will have to be done to find the right size and flow of air (one, two, or three tubes) but it is an easy thing to think of what a jet engine can do.
A Jet engine requires Compression. So compressor blades which are spun up usually by electric motors but the motors are disengaged once combustion occurs and the combustion turns both the fan blade (pulling in air) and the compressor blades( holding back the combustion and compressing gases then expelling them out the rear.) the fan blade and compressor blade or blades are connected via single axle. Really to start a jet engine you only need the fan to turn with air intake so that the compressor blades also turn. Therefore you can take what you have add compressor blades, a restricted exhaust nozzle, your ignition source and use your hair dryer even on cold setting to spin up the blades. Would love a 3D printer. Love the great projects you have going.
13:00 "How to use all of the air without losing thrust" My answer is as boring as obvious... "Multiple fans on the axle, deviate some of the air flow, use spark igniters..." => Build a miniature jet engine... turbojet, ramjet,... with an AFTERBURNER ! 🔥🤘😎🤘🔥
Taper the end down and put a smaller double sided cone inside the end of it and it forces the air out a little fast and through slightly smaller hole so there will be more fire in contact with the unlit air or fuel and help combust a little more efficiently
Oh hey one thing that really matters is the distribution and mass of droplets of optimal diameter to get complete combustion. Although fuel injectors work they're not ideal for certain applications. For a good time check out a contraption called a 'spinning cup burner' that gets used to get a gnarly hot flame for flash boilers. These were popular with folks messing with high speed steam powered cars back in the '80s and '90s. :-)
they were using a salon hair dryer - besides the fact that it's clearly a salon, you can tell because they always come with much longer cables. they also have much better (hotter) heating coils and controls (if you haven't tried one at home, do it, it's a game changer if you can afford the splurge). I also think it was just hairspray being sprayed in, not brake cleaner, which is more volatile and flashes at a lower temp.
add a line that feeds the fuel into a small fan enclosed for pressure, with a second line the feeds back the liquid that didn't turn to gas yet, improved fuel efficiency. I hope i said that in a understand way. or create a two stage process for the liquid fuel heating up.
I think for maximum thrust with minimal waste, you should go for a high-bypass design that incorporates a turbine downstream, maybe five centimeters behind the ignitor. Put that rotational force back into the impeller, and then get as much liquid brake cleaner as possible to steadily drip onto your nicrome wire. The increased airflow should counter any resistance from the turbine, while also allowing you to use less fuel overall.
Have a fan that high produces high speed air which leads into a hallowed shock cone we're on the inside of the cone is the wire and behind the cone is a tube on the sidewall of the jet engine with holes that spray fuel upwind and towards the center of the shock cone where it is ignited and it's heat should preheat the air hitting the shock cone farther Downstream is the fuel tube in a coil the middle which goes into a straight line outwards and through the engine wall to go to the fuel Inlet then at the very end of the jet engine is another fan with metal blades to withstand the Heat speeds the hot air back up and if spinning fast enough and has enough blades depressurizes the air. (Sorry about my spelling I have not fully learned to spell)
You might be able to put the coanda effect to use by putting a sphere between the fan and the igniter. you might also make the sphere an ionic thruster to allow you have control over the airspeed.
you can atomize the air before igniting it using a makeshift carburetor before the fan and you can heat the fuel by coiling it around the diameter of the tube to make it ignite easier
Hahahaha! Asking me for advice on rocketry? No problem. First, fit a speed controller dial to your impeller to enable fine tuning of fan speed. Make two feed nozzles to turn liquid to vapour when pressurised. Place feed valves on the lines so you can adjust the amount of each liquid. Connect one to a supply of liquid brake cleaner (pro tip - you don't need to get it in spray cans). Connect the other to a supply of hydrogen peroxide. The two in combination should make your flame blue as you adjust the peroxide flow, and should make your burn more stable at higher fan speeds. If you want really good thrust, fit a stepped conical nozzle to the jet outlet so the thrust has something to push against. It works in zero gravity, and should be even better with atmospheric pressure to work against.
Have the copper coil tube sealed at the end, and make tiny holes around the last coil. This will increase the pressure it comes out at and mix it better with the air.
what i think you could do to make it use all the air at full power is to force the fuel out many tiny holes to increase surface area of the fuel in the engine, kinda like that one Mythbusters coffee creamer experament.
I say small 30degree angled holes behind the igniter angling towards the ignition coil. Air from behind and the fire should pull its own air current from the holes to provide extra air to combust
Drill some holes in the fuel line so it sprays fuel outwards. You will still get some onto the igniter which will create a pilot light. Then the radially sprayed fuel will be ignited by the pilot light and burn in the rest of the air in the chamber.
Here's an idea, pass the air through a CD nozzle and inject the fuel with one of your brass tubes at the throat and ignite there. The combustion is performed at the narrow throat where the air concentrates, allowing it to be used more thoroughly. Also the CD nozzle provides additional thrust. There are still quite some things that I'm afraid perhaps didn't propose, and I'm definitely not great at physics but I suppose it's not a bad idea.
Same spiral coil you already have but drill micro holes all the way around the coil so the fuel goes in all directions. More surface area of both fuel and air contacting and small holes might make very fine flows that burn very efficiently. Potentially need to plug the end to add pressure to push out the holes, or make the holes mist the fuel into the air on that coil.

"An example would be a workshop mechanic who uses brake cleaner aerosols routinely. In addition to the significant risks Tetrachloroethylene carries, the substance becomes an extremely poisonous gas called Phosgene when it is heated to temperatures above 315 degrees Celsius."
And

The simplest way I can think of that will probably allow you to use more of the air for combustion is to basically use an afterburner, which just injects more fuel in the hot, lean air after the engine core. But, and here's the part that makes this super simple, is that you inject the fuel in at the edges at the intake. The fuel would have time to mix and atomize with the incoming air, and the existing 'jet core' would act as an ignition source. Real afterburners aren't efficient because the core gains efficiency from igniting the fuel/air mixture under compression while the afterburner uses uncompressed mixture to burn, but you're using uncompressed fuel/air mix the whole way through so this is entirely bonus thrust for this design.
The whole system is already an afterburner though.
Essentially just add more injection points to spread out the fuel during combustion. I think the hard part is going to be protecting the acrylic though.
First don't use acrylic second make a ring of a aluminium pipe with some hole for injecting fuel. And why not use a bldc motor which automatically gets lower when fuel less burns? and tries to use more flammable Gus with high pressure..@@Antal-te6rj
I wonder if adding the fuel before the fan would help, All tho I wonder if the diluted fuel would be difficult to ignite and if it would melt the and bun out the fan.
Pseudo-intellectual attempting to explain what an afterburner is to someone who already knows.
13:30 if you had a pressurized air tube around the entire acrylic tube that allow more airflow in so then the engine could have. More or easier combustion. Plus thrust.
Use Dyson tech, Put additional holes on the side of the acrylic to let in more air. The fast airflow will suck in additional air into the pipe. If you want better mix add additional length to the pipe and put a nice cone shape funnel at the end of the tube/pipe.
To use the air and fuel mixture efficiently and take advantage of them u need more to pressure the air as u mentioned for the impeller
You are confusing detonation with expansion. Jet engines burn fuel then use the heat to expand air. You DON'T want a 100% air combustion. You want the least amount of fuel burnt to produce the most amount of thrust/work. You do this by creating a "flame can" to protect the fire from being blown out with inlet holes that allow for precise and controlled mixture of cool air to mix with hot air as it exits to the exhaust turbine. There are many books on turbojet operation that explain this process. Best of luck.
its not a turbojet its an electric fan with something akin to an afterburner there isnt any turbine which is part of why its not going to get high thrust and compression ratios its basically just a butane torch lighter at this point
Yeah use this exact set up with hydrogen 😂🎉 would be super awesome.
My best idea for improving the design is a better air to fuel mix.
Currently you have a lot of air and not so much fuel. If you make a spiral coil with the copper tube, you can make a bunch of tiny holes along it's length in order to pump more fuel into the stream, you can try both a simple spiral with a crimped/soldered end tube, or one with both ends of the tube getting fuel pumped in, and the spiral meets at the center, where there would be a the end point/mid point of the tubing. This design probably needs a pilot flame behind it, at least for ignition, but might need it in order to heat the fuel up before injection/ejection.
I would be more worried about getting more air into the middle of the flow first. Then add fuel.
But I do agree that more fuel equals more flame.
I'm just thinking of getting a more complete burn within the tube.
Thanks for the reupload Integza, I was just about to do this at home
Hey Integza , for improved propulsion, it's recommended to channel the air flow through the center while directing the fuel to the outer side. Utilizing a technique similar to the porous knife demonstrated in your video can facilitate better mixing of the fuel and air, enhancing overall efficiency and performance. And you forgot to destroy a tomato in this video.

Hello @SaraBryan-sw7ri congratulations
Still waiting for the turbojet v2! :)
2:18 hilarious moment 😂😂😂
I followed your RDE video here. Here’s my suggestion:
An automotive spark plug enters the tube from the side. Covering half of the sparky part is a partial cover which shields the spark from the fuel-air flow stream and initiates a radial rotation of the flame front. Upstream of the spark plug are two wire screens in parallel, which form a flame suppressor.
Also upstream is a Tesla check valve, to minimize the pressure waves going to your fresh air pressure source: a shop vac. Fuel and air are mixed after pressurizing.
Fuel, air, spark, rotational flame front. Adjust the exhaust tube length and spark frequency to get the right pressure for detonation.
Voila!
Thanks Integza!
Thank you so much for the support 😁

Hello @sidtheguy313 congratulations
the text is partly from the translator because I don't know some terms, I'm from Poland and I don't want to make a mistake and embarrass myself :D
my idea is to make a similar design to military jets, use multiple fuel injectors in a cylindrical shape as you did in previous videos, for example "I built an Electric Jet Engine from scratch" 6:07. Then the fuel you would use if you wanted it to be heated would have to use a separate heat source oooor, which is a better idea in my opinion, change the casing to a metal one, unfortunately it will no longer be ZE FLAMES but if you want to use as much air as possible for combustion you will not be able to use the outer layer air as an insulator. Returning to the fuel line, you will be able to wrap it around the exhaust to, firstly, heat the fuel before ignition, and secondly, it will act as a small radiator, so it will slightly reduce the temperature of the casing, just something similar like the raptor engines in SpaceX rockets are cooled.
Finally, I will just add a few comments so that you remember, firstly, when you record, remember not to put it too close to the camera as you once melted it, the same applies to the wind meter, and secondly, remember about the final test with the tomato.
Even if I don't win, I hope I helped
and I remembered it, but it's probably too complicated for such a small scale, you can use 2 or more propellers to increase the air pressure and speed, like in turboprop engines
Increase the power of this by Creating a nozzle which thins Towards the end of the ignition chamber and then widens out again this will give you more compressed air just before the already ignited Fuel and air this means all the fuel and air expands together giving the engine more draught and more power.
@Integza, All you need to do is put a nosle on the exit/front of the combustion chamber like they had in the original video. If ypou narow the escape of the flame it will burn up more oxigen.
Time to try this a home! I'm gonna attach this to my longboard!
Integza you dangerous madman, you made the dryer get hotter, and didnt change the plastic to something more fire resistant, you are creating a massive fire hazard.
Hi Rocket Man. I will watch it again.
Just a heads up. Propane tends to be used as an aerosol propellant. It is possible that the propane in the breaks cleaner is being ignited. If this is the case, the fuel-to-air mixture needs to be between 2.15% and 9.6%
You Could try using static mixers to mix the fuel and the air for combustion. Try using a Kenics Mixer or a Sulzer Mixer.

Hey Integza! You need a flame shroud or tube. What you are building is a Turboramjet or Air turborocket.
It is the very simple version of a jet engine. Also a company is using it for a SSTO type rocket, using the fanjet portion in atmosphere then using like a rocket out of the atmosphere.
So you need a flame shroud to keep the flame protected and allow it to heat the air completely. Its close to what you did, just a tube with lots of holes in it. Longer tube, more holes, make power!! Good luck! Feel free to reach out and geek.
Hi integza, I'm a Brazilian fan and I always wanted to see you building a remote control plane. I have a simple but interesting idea, so you would build with foam, Balsa wood and 3D printed parts . With this you could insert a compressed air engine. I know it can be very complex but it would be very interesting to do this project. (sorry for my English) PS: the engine could be based on a tesla turbine.
"Do not try this at home"
Also him: "I put the links to it in the comments for testing"
ad ends here ➡ 6:27
2:27 you can see it works like a jet engine but it doesnt have after burner
Alright integza , here is my idea: your model reminded me of an afterburner rather than the turbo jet it self, so I come up with 3 main changes.
1st scratch the combustion tube and coil the copper fuel tube over the nicrom wire and drill tiny holes at the end of the copper tubing,
Thus the fuel will get heaten up beforehand and we can let all the fuel get contact with the nicrom wire.
2nd change the fan desing on the electric motor and make it like a multi stage fan and add a 3d printed or acrylic funnel like desing behind of it, this way, I believe, we can divide the incoming air into 2 sections with one being in the free flow state to keep the system cool and rest of it to mix more oxygen into fuel.
3rd change is not even a change but more like keeping the first desing by keep adding fuel in the front so we can get a afterburner effect.
Some extras might be adding a selenoid constraption with potantiometers to control the fuel flow and adding a exhaust cone to end.
These are what I have come up with so far, I can try to draw a detailed model to explain all beter maybe. And it might be good idea to add that I have no experience with jet engines. Also I have used a lot of inspration from your older electric jet engine project and the EDF after burner one.
I think a suction would work, or something like what the SR71 blackbird uses.
Or you could use a longer version of what you have now, pulling as much air as possible in and useing more time to accelerate it.
If i remember correctly he didn't have that disclaimer at the start of the video, i supposed thats why he had to re-upload

in the description of this video, he explains that it was because the original was demonized.
The hair dryer you were looking at was an older model where the heating element is in the back similar to a room floor heater. Electric element but it was in the rear and the blowers also sucking from the heat and pushing it forward
Id reccommend a clonical MIG shroud, its designed to take the maximum output of gas and force it into a tube shape. It could help you achive a better gas flow rate as they often run at 11 liters per minute
Reupload?
Age restriction happened.
To improve the hairdryer engine, couldn't you use the same style as a typical jet engine? Multiple fans - 1 to bring air in and one to compress it? maybe using a belt fan/larger size for the first and a small server room fan for compression?
Better yet, use the fan systems from two different hair driers. You use the normal bladed fan to accelerate incoming air which is then fed to an impeller system to compress the high-speed air to a greater degree.
So, adding a supercharger on it. I might be wrong, but you guys could correct me on it.
the guy who had the most liked comment on the original video is gonna be so disapointed
What did he say?
1. We can use a contra rotating propeller to produce more thrust and hence more power.(The propeller can have max. 4 blades and not more than that.)
But it comes with its own issues. When thrust increases by so much there is a slight chance that the ignition might not work properly and might fail. Hence the best solution that I can think of is that you can improve the covering of the ignition and design it like a missile but with a small perforation at the initiation. This way we can produce more thrust without compromising the issue of ignition.
2. An afterburner might work as well.
An afterburner means more space and hece some changes to the design. First issue is the issue of the fuel rail coming in between the ignition and the afterburner. For this you can just coil the tube on the outside of the ignition and then inject. Another sub tube will inject the fuel into the afterburner.This way a lot of more thrust will be generated and fuel efficiency will be maintained.
3. The exhaust diameter must be of a bit smaller so that the pressure is created inside the chamber and this way it theoretically could produce so much thrust that it should be able to propel your skateboard :)
And yes, Tomatoes are bad!!!
We hate tomatoes!!!!!
Great video, although at the moment its a glorified blowtorch and not a jet engine, but still, good job. A tip I have is that you could just use a convergent pathway right after the fan and get a more powerful motor. As you likely know, that's how air is compressed in the compressor in gas turbine engines, and I'm sure it'll work for you as I know a thing or two about gas turbines and worked on them in the past. Speaking about Gas Turbines, atlhough it would be a much more time-intensive project and would require some metal-working skills it would be great if you could do a version 2 of your Turbojet Engine on a larger scale and using less 3D-printed parts which are highly susceptible to melting. I'd gladly wait for a while for that.
Now you can try it with a leaf blower
jetpack joyride

Having watched the video until 3:00, I guess it is sparks from the DC motor‘s brushes. Now continue watching.
Jet engine project
Well I watched an 8 minute video on how a turbo fan jet engibe works. Got the general idea of it. Took a can, PVC pipe as the inner co pressor that directs airflow towards the rear inlet, placed a cap on the end and put aluminum flaps in that area for direction of airflow. The cap holds the fuel. I ignite it and ram air fliw into the front of the jet. Tje airfliw passes through the PVC tubing for airflow direction and over the ignited fuel whixh produces thrust and afterburn. At this point in time I didn't have a turbine/fan so I simulated the turbine with a hair dryer as air flow. Now, I am currently working on an electrect ducted fan blade for a bigger turbine system.
Deja vu 😅
The unemployed homie on a Tuesday evening:
Hi kids! Don't try this at home. Also, here are the schematics, and the best do it at homer wins a 3D printer. 😂
Try it everywhere else but home
regarding this video, I would suggest using a car vacuum cleaner, but used upside down, that is, on the exhaust, it has more force.. and if you also printed some static steering paddles, it would be amazing because it wouldn't give the flame back...
I can’t use the 3D model but I would suggest that thru the acrylic tube make small holes and insert injection like needles. Thru these needles use O2 gas just before the ignition and use a gauge on O2 cylinder to control the thrust.
This basically be like 4 holes on the tube and some needles with O2 flowing in them and solving the problem without having any issues with the fan speed.
I may be wrong but you can try on a 3D model.

i am no expert but i have an idea, so maybe u can put the nichrome wires around the injector and put bunch of holes to the injection tube, that way it will have more time getting oxygen without fighting the wind. and also putting a narrow nozzle in the tip will make a more controlable and stronger thrust i guess.

Hey Integza, I had an idea for a future video, why don't you revisit your rotating detonation engine, and try making it using NASA's 3d printable GRCop-42 Copper that they used to test the RDE
Hello!
As stated in the first video upload, I believe the issue with the « new » air drier is the air to fuel ratio (AFR) is out of the flammability range for the brake cleaner. Thus the brake cleaner may just dilute in the air without burning. If this theory is true, then decreasing the AFR by injecting brake cleaner by 2 bottles may be the solution to get a bigger flame than the current one with the broken air drier.
Then, looking at the custom solution, adding a second injection ring along the internal wall of the tube, about 10cm behind the combustion chamber could be enough to use all the air available in the tube. Combustion would be launched by already burning gaz from the inner flame. This would work as a post combustion on a jet fighter aircraft.
Hope this helps!
2:19 yep IT wasnt conected
10:10 "If it sounds clever - it probably is" You have a very sharp-mineded grandfather with good sence of scientific humor.
The obvious thing to do is to channel some of that air into the combustion chamber. Just some small tubes (with a flair at the end) directing some air into the combustion chamber.
Some tweaking will have to be done to find the right size and flow of air (one, two, or three tubes) but it is an easy thing to think of what a jet engine can do.
A Jet engine requires Compression. So compressor blades which are spun up usually by electric motors but the motors are disengaged once combustion occurs and the combustion turns both the fan blade (pulling in air) and the compressor blades( holding back the combustion and compressing gases then expelling them out the rear.) the fan blade and compressor blade or blades are connected via single axle. Really to start a jet engine you only need the fan to turn with air intake so that the compressor blades also turn. Therefore you can take what you have add compressor blades, a restricted exhaust nozzle, your ignition source and use your hair dryer even on cold setting to spin up the blades.
Would love a 3D printer. Love the great projects you have going.
Video Idea : “Build a Functional Jetpack Using 3D-Printed Parts and try it out.”
13:00 "How to use all of the air without losing thrust" My answer is as boring as obvious... "Multiple fans on the axle, deviate some of the air flow, use spark igniters..." => Build a miniature jet engine... turbojet, ramjet,... with an AFTERBURNER ! 🔥🤘😎🤘🔥
Taper the end down and put a smaller double sided cone inside the end of it and it forces the air out a little fast and through slightly smaller hole so there will be more fire in contact with the unlit air or fuel and help combust a little more efficiently
Thanks integza, you always help me gain alot of knowlebge.
Oh hey one thing that really matters is the distribution and mass of droplets of optimal diameter to get complete combustion. Although fuel injectors work they're not ideal for certain applications. For a good time check out a contraption called a 'spinning cup burner' that gets used to get a gnarly hot flame for flash boilers. These were popular with folks messing with high speed steam powered cars back in the '80s and '90s. :-)
You could use the ionic tornado generator from Plasma Channel to get a better airflow (streamlined and compressed)
they were using a salon hair dryer - besides the fact that it's clearly a salon, you can tell because they always come with much longer cables. they also have much better (hotter) heating coils and controls (if you haven't tried one at home, do it, it's a game changer if you can afford the splurge). I also think it was just hairspray being sprayed in, not brake cleaner, which is more volatile and flashes at a lower temp.
add a line that feeds the fuel into a small fan enclosed for pressure, with a second line the feeds back the liquid that didn't turn to gas yet, improved fuel efficiency. I hope i said that in a understand way.
or create a two stage process for the liquid fuel heating up.
I think for maximum thrust with minimal waste, you should go for a high-bypass design that incorporates a turbine downstream, maybe five centimeters behind the ignitor. Put that rotational force back into the impeller, and then get as much liquid brake cleaner as possible to steadily drip onto your nicrome wire. The increased airflow should counter any resistance from the turbine, while also allowing you to use less fuel overall.
For extra air and speed you have to make gap between motor and acrylic tube . this technique is used to fill more air in less time
Have a fan that high produces high speed air which leads into a hallowed shock cone we're on the inside of the cone is the wire and behind the cone is a tube on the sidewall of the jet engine with holes that spray fuel upwind and towards the center of the shock cone where it is ignited and it's heat should preheat the air hitting the shock cone farther Downstream is the fuel tube in a coil the middle which goes into a straight line outwards and through the engine wall to go to the fuel Inlet then at the very end of the jet engine is another fan with metal blades to withstand the Heat speeds the hot air back up and if spinning fast enough and has enough blades depressurizes the air. (Sorry about my spelling I have not fully learned to spell)
You might be able to put the coanda effect to use by putting a sphere between the fan and the igniter. you might also make the sphere an ionic thruster to allow you have control over the airspeed.
you can atomize the air before igniting it using a makeshift carburetor before the fan and you can heat the fuel by coiling it around the diameter of the tube to make it ignite easier
W i n n e r
control the fan and fuel based on the ratio
also do a funnel going into the engine combustion chamber so you can condense air even more
Hahahaha! Asking me for advice on rocketry? No problem. First, fit a speed controller dial to your impeller to enable fine tuning of fan speed. Make two feed nozzles to turn liquid to vapour when pressurised. Place feed valves on the lines so you can adjust the amount of each liquid. Connect one to a supply of liquid brake cleaner (pro tip - you don't need to get it in spray cans). Connect the other to a supply of hydrogen peroxide. The two in combination should make your flame blue as you adjust the peroxide flow, and should make your burn more stable at higher fan speeds. If you want really good thrust, fit a stepped conical nozzle to the jet outlet so the thrust has something to push against. It works in zero gravity, and should be even better with atmospheric pressure to work against.
Have the copper coil tube sealed at the end, and make tiny holes around the last coil. This will increase the pressure it comes out at and mix it better with the air.
what i think you could do to make it use all the air at full power is to force the fuel out many tiny holes to increase surface area of the fuel in the engine, kinda like that one Mythbusters coffee creamer experament.
I say small 30degree angled holes behind the igniter angling towards the ignition coil. Air from behind and the fire should pull its own air current from the holes to provide extra air to combust
Drill some holes in the fuel line so it sprays fuel outwards. You will still get some onto the igniter which will create a pilot light. Then the radially sprayed fuel will be ignited by the pilot light and burn in the rest of the air in the chamber.
Here's an idea, pass the air through a CD nozzle and inject the fuel with one of your brass tubes at the throat and ignite there. The combustion is performed at the narrow throat where the air concentrates, allowing it to be used more thoroughly. Also the CD nozzle provides additional thrust. There are still quite some things that I'm afraid perhaps didn't propose, and I'm definitely not great at physics but I suppose it's not a bad idea.
Same spiral coil you already have but drill micro holes all the way around the coil so the fuel goes in all directions. More surface area of both fuel and air contacting and small holes might make very fine flows that burn very efficiently. Potentially need to plug the end to add pressure to push out the holes, or make the holes mist the fuel into the air on that coil.
