Your burner assembly needs to be placed inside the body of the engine along with a couple of baffles, one separating the 2nd & 3rd fan and another one behind the 4th to create the front wall of the combustion chamber. The first baffle should reduce the diameter of the air passage and the 2nd blade needs to have the tips trimmed to be just a wee bit larger in circumference than the pass through in 1st baffle. The hole in the 2nd baffle should be a little smaller than the pass through hole in the 1st baffle and the tips of blades 3 & 4 trimmed to be a wee bit larger than the pass through hole in the 2nd baffle. I suggest one more baffle at the end of the tube where the conical nozzle piece attaches. It should be about 75% the diameter of the outlet hole in the nozzle. Your fuel feed lines should be introduced about 1/4 of the length of the combustion chamber back from the 2nd fan blade baffle. Will your engine work like a proper air-breathing reaction motor? Maybe. Right now your design lacks any meaningful back pressure. The narrowing of the pass throughs will create a marginally better amount of compression and speed up the airflow due to the improvised Venturi effect that the first two baffles provide. The third baffle in the rear in concert with a defined combustion chamber will allow a modest amount of back pressure and as the combustion gas exits through the last baffle’s pass through, it’ll expand in the inside of the nozzle and push against the inside of the nozzle and the rear baffle as the gases are exiting through the nozzle; this in turn will create some modest amount of forward thrust according Newton’s 3rd law. As an aside, with the modifications I’ve suggested, the fuel ports into the bottom of the nozzle can be repurposed with a secondary fuel supply and potentially act as a weak afterburner stage. Good luck.
brother u forget to mention where is the combustion fusion there is no fuse/ spark plugs and the air is not even compressed enough nor the structure is strong enough to withstand that kind of air pressure which a real jet needs let along if it can even survive the combustion from the fuel similar to car engine and then use that torque to push air and also control the intake propeller in front to balance out the air speed aka u increase the fuel combustion u also increase air intake and also get more compressed air to get in the ... what im saying is this video has no clue about what and how a jet works or even how to build a proper one this is more like a 9 year old making a small town city with toy type show case of jet nothing more then a gimmick
@E Van wait ?? turbine ? engine ? ur addressing + comparing it to something that has no similarity. plus that has no shape of a turbine. u can call if a toy thats more better
Thats why i jumped right to 12 minutes right away after reading the first comment... It looks like thats how common people look at gas turbines... Dont they inform themselfes how turbines are working before they glue something like that together?
in the jet engine, the air is compressed and there the fuel is added then ignited in the compressed chamber, so the thrust is multiplied by the expanding air. And also the jet engine not necessary need turbine, as long it has continuous compressed air and fuel that exploded it can called a jet (turbinless jet is called ramjet engine) . But this video, fuel is at the end side of blade. Moreover it ignited at the outside. In conclusion, its just a rotor that bursting fire.
@@ketchuplover3197 what he built is a model of a ducted fan with an afterburner. Wich is not a jet. It's a ducted fan with pointless afterburner. That would not creat any trust because you can't expect to get any pressure to build up inside the duct. Trust comes from fuel mixed with compressed air. You can't create pressure in a civ.

Very Cool! Although like the naysayers said, it is not a true "jet engine", as the combustion is not occuring between a compressor, and turbine, (yours is after the fan), the principal is still somewhat similar for demo purposes to younger people. Great job! You would be a great educator to spark interest for those who might decide to pursue the science of it further in life.
I understand what you're trying to convey here and getting kids into science is something I'm ALL for. But my biggest bitch is our educational system in North America, mostly the United States, (sorry, truth doesn't care about feelings). We, in this educational system, have forgotten to teach our children how to think critically/rationally. And because of this people, don't mature with confidence in their own abilities to find truth in what's presented to them. Instead of maturing and growing up, people just get older and are easily moldable in their perceptions of sometimes what's right in front of them/us and obvious as things can be. But we have no tools to think in a rational/critical manner. THIS is why North Americans, score in the lower ends of first world countries in many, many areas.
It has an afterburner but no combustion chamber, the idea of a jet engine is to compress air, not really to just make many turbine, the air is not being compressed just fanned toward a flame (as someone else said). It is very cool but after consideration it really is not similar to a jet engine.
@@KanadMondal Yeah. Funny. It reminded me how when BBQing, I quickly get the flaming black coals red hot, ready to go in a matter of minutes simply by directing my leaf blower on full blast into the metal container. BBQing afterburners.
Nice job, but I see at least 2 big problems: - all your fans are on the same axle, which implies the air flow is at about a constant speed from the second fan. My works on propfan showed each step must be spinning at a higher speed than the previous one, which is essential with contra-rotating fans to avoid gyroscopic precession, but the idea is still the same whatever flow you're working on. - each subsequent step must be smaller than the previous one to increase air compression and thus speed at the output nozzle. To combine the two, the simplest is to have a single motor shaft with belts and each fan on its axis (all collinear) and proportional gear reduction. It's a tad more complicated than this one (because of the bets and the separate axes), but it makes it much more efficient. Also, how about soldering the pieces together (not even brazing or welding) once superglued to reduce the air leaks?
@@success_studio feel free to email me. What I'm saying is that all the work is done by the first fan. The second fan provides no acceleration -- or something very marginal due to the fact that the first fan is not physacally "perfect", theory and practice may differ. On the second (and all further other fans), the input speed and output speed are pretty much the same if both fans are the same size and speed, even contra-rotating. Now, contra-rotating is the reason for the extreme noise, which is mostly generated between the propellers: Since your fluid is spinning in one direction and you're trying to reverse that spinning direction, so, yeah, your air will go from -speed to +speed, it's just perpendicular to the axis you want:and has absolutely no effect on the propulsion force, or marginally by accumulating pressure at the tips of your fans (not where you want it, unless it's severely funneled). Also, the distance between propellers is very important to avoid unwanted turbulence. If the sound is what you want, then it's fine. If you're looking for any form of thrust, think again. Have a look to Integza's channel, he's trying for ages to make a working jet. Also, if you want to explore that domain, you can have a read of NASA's report about... propfans (id 19870019120). It explores the physics and fluid dynamics of 2 contra-rotating "special" propellers and all the tests made in different configurations. I know, 476 pages... unless you're trying to build one to create something even better, that's a pretty boring read of 476 pages, but totally worth it to figure out what's hidden behind it. Enjoy!
I'm just coming on here to point out for many of the people who are arguing below that it isn't a jet engine. This IS a jet, but it isn't an engine. What makes an engine an engine is the fact that on each cycle, more energy is released than is required for the next cycle. The next cycle gets the energy it needs, and the remainder of the energy is exhausted to the environment. Jet engines don't have cycles in the same sense as a piston engine, but they are analyzed the same way. For this to have been an engine, the energy released by burning the fuel would have to be captured in some way (turbines after the burn chamber) and put back into the input side for the next cycle -- to wit, if the prime mover (the electric motor) is removed and the jet doesn't self-sustain, it isn't an engine. As an aside, what this guy did was basically built a model salamander (those heaters that people have in their garages and on construction sites that look like a jet). Mind you, I'm using a practical definition of an engine, not the exact thermodynamic definition, though I've never seen anything to indicate that there's any such thing as a non-self-sustaining heat engine.
@@staticmode25 dude listen!!! for jet engine it requires turbine to drive the shaft again and again, and it is not simple as u think... even for a small jet engine rpm is 1lakh and u can hear super sonic sounds from engine.. heres I cannot see any turbines or internal combustion chambers, diving shafts etc.. and finally the engine in the video yes it is a jet engine (only for the people who have no idea on actual jet engine )😅
Dude back off I believe the kid did well just showing the simplicity of it. So yeah it was obvious never to use glue to bind it but this was to show others how simple something like this is to people who though otherwise the opposite. Give the kid a break will ya.

But im sure the kids aware never to use glue irl for real flight. That's common knowlage. Duh
It's just a Jet Kid Toy, unfortunately it's not a real mini turbine jet engine that I imagine before. I have seen full view 12 minute and regret. Wasted time
I think this is another one of those east indian video's trying to make them look smart... but alas, it always backfires and makes them look dumber. in fact if I knew how jet engines worked at 6 years old, I think these guys are going backwards in intelligence :-\
Chill guys , you seems like offended for no reason. Instead of saying his whole experiment wrong why don't you just say the title of the video is wrong and it should be flamethrower or something. Unlike you, english is not his first language and you should encourage people for what they are doing.
I’m only 12 (although all of my teachers say I am incredibly smart for my age) and I know that this is not at all a turbojet engine (which is what he was quote on quote “making”) although you did get the first 2 stages correct, there are 3 stages which is where the exhaust spins fans behind the flame which are connected to the “fans” in the front which causes it to suck in more air which causes it to burn faster which causes it to spin faster which causes it to suck in more air which causes it to burn more which causes it to spin faster and this cycle repeats and, ba da bing ba da boom you now know how a jet engine works. Thank you for your time.
this is not a jet, this is an ordinary nozzle, there is no need to make blades, but just make holes in the radius, the only engine in this design is the Chinese motor
Ah fevikwik... that brings back some memories XD And yes, JET engine. Held together with crazy glue... I think the 3D printed engines might even last a bit longer; since the blades actually spin???
it certainly won't break any sound barrier anytime soon, view it as a scaled down simplified but with a similar concept to that of a jet engine, because what jet engine is it's basically a bunch of high speed turbine sucking in air from the front, pressurize the air in the middle, and combust it with spraying fuel as the air were being forced out at the rear at a very high velocity, thus achieving the speed of sound. believe it or not, the concept of a jet engine is actually simpler to understand than that of a regular piston engine which a car uses, because it really is just a bunch of giant fan and some pipe that spew out fuel, the rest is physics.
At least Efforts taken Truly admirable here as above who does this in slums as we hear background noise in a country like India ,for Aeromodelling enthusiasts and other scientific platforms there is little or no space at all, only the glamour, rich and mighty with little or no knowledge, or interest just pushed in for photo pics..Thanks to this lad implementing his soul to the tech world.
In the beginning of the video, when I saw he was super gluing the little metal beam to the cylinder, I thought wow! That glue must be top tech that can resist jet engine heat! 😐
25 years ago before model jet engines were available commercially, folks were making them out of compaing gaz containers and using VCR head bearings. Someone was machining the compressors and selling them at flying events. This was pretty clever, but I doubt it can produce useful thrust.
Guys stop being rude, it might not be a jet engine but you don’t have to make fun of it, and what he made is an experimental turbine engine that a company made then they scrapped the project.
Err ... I'd call this a fan blowing lighter fluid out the back of a tube. It might produce barely non-zero thrust because it is basically a simple afterburner. The jet engine itself is missing, there's an electric motor with fan blades instead. All that being said, I liked this video!
I thought this was going to be a functional turbojet or something.. oh well it's a start. Got to have a compressor with tolerance so that proper compression takes place without pressure loss through intake, etc.. I define the jet by it's ability to self sustain,only use electric to start it up. I'd start with an old turbo or something.. I'm currently dissecting a Dyson for a small compressor wheel.. it is a start though sir..
OK, this is not a jet engine. But he had fun, and this is exactly the kind of thing I used to do when I was a kid. I didn't know what I was doing but I did my best, and learned a lot along the way. Eventually I got into the design and engineering of building systems. Kids, learn how to build things with your hands!
man, a jet engine is not so easy to manufacture, but if you had made a combustion chamber not between the turbines but between them, maybe something would have happened
When I was in school, I also made a jet engine based only on pictures from magazines, when there was no Internet yet, I did the same as you, for the sake of interest)
I built one of these in my 11th grade physics class. I had the VoTech school make the outer casing and my art department fired the compressor blades that I made out of clay. When we tested mine and used the after burner which moved 20 % of the fuel to the back, it tore off of the stand and went flying down the parking lot. It broke 2 10,000 pd bolts by shearing them off. I got my A in Physics.
Great effort and creativity in trying to explain a concept, Although not very accurate on the working principle of a jet engine .. Appreciate what you have done. Cheers.
this ain't a jet engine, although in fairness you did give me a few ideas there to miniaturize stuff, with a few mods on this design i think i can make a true mini jet engine. if nothing else, this design can take out a single robber's face if correctly-placed by the door at night (weapon of opportunity from household items; don't laugh at a steel spoon for being a steel spoon, in my hands i can stab that into someone's jugular or carotid attacking me while i'm eating), he'll still be alive, but now he has a real problem in his very face, his painful broken face is now his problem. thanks dude.

Very nice you did something from nothing! You shold try to redesign it do not listen to any one they expect to see titanium fans and other hi-tech things that they can't rebuild
"Jet engine" my ass! First, there are rotor stages, but no corresponding stators. Second, the rotor "stages" don't compress the incoming air. They merely accelerate it. Finally, the continued accelerated combustion of the butane is reliant upon the electric motor. If this were indeed a jet engine, a set of turbine stages being turned by the expanding combustion gasses would draw in air trough the compressor stages and sustain the combustion in the burner "can". This is about as much a "jet engine" as lighting a fart.

So yeah it was obvious never to use glue to bind it but this was to show others how simple something like this is to people who though otherwise the opposite. Give the kid a break will ya. I mean like when I started all I had were thouse materials that this kid used when I was like 5 years old making and tinkering with some stuff did it ever occur to u that this is a less the 10 year old. Huh. Trust me when I say cause I make a couple million a year with my career as a master maker that this kid did a great job for a beginner lesson. But im sure the kids aware never to use glue irl for real flight. That's common knowlage. Duh
idc whatever you people say but the work done by this man is still impressive. It's very cool dude keep the work going great job!
That's not a jet engine, but still impressive and took time to make!
this probably took 5 minute to make lol
@@yosltsum it took some time right?😅🤷♂️
It's just a Jet Kid Toy, unfortunately it's not a real mini turbine jet engine that I imagine before.
I have seen full view 12 minute and regret.
Wasted time
This is just a flamethrower and unfortunately not a successful one. I don't think you understand the principles of thrusting and engines.
I think this is another one of those east indian video's trying to make them look smart... but alas, it always backfires and makes them look dumber. in fact if I knew how jet engines worked at 6 years old, I think these guys are going backwards in intelligence :-\
it's more like a flame throwup!!! .. 🤮
@@harleyme3163 If they try they can raise a person like Bose. But I started to think they don't even try these times.
Chill guys , you seems like offended for no reason. Instead of saying his whole experiment wrong why don't you just say the title of the video is wrong and it should be flamethrower or something. Unlike you, english is not his first language and you should encourage people for what they are doing.
@@depinder he did it wrong.
I’m only 12 (although all of my teachers say I am incredibly smart for my age) and I know that this is not at all a turbojet engine (which is what he was quote on quote “making”) although you did get the first 2 stages correct, there are 3 stages which is where the exhaust spins fans behind the flame which are connected to the “fans” in the front which causes it to suck in more air which causes it to burn faster which causes it to spin faster which causes it to suck in more air which causes it to burn more which causes it to spin faster and this cycle repeats and, ba da bing ba da boom you now know how a jet engine works. Thank you for your time.
SUGGESTED TITLE :
HOME MADE INEFFICIENT BLOW TORCH
this is not a jet, this is an ordinary nozzle, there is no need to make blades, but just make holes in the radius, the only engine in this design is the Chinese motor
true very true

Ah fevikwik... that brings back some memories XD
And yes, JET engine. Held together with crazy glue...
I think the 3D printed engines might even last a bit longer; since the blades actually spin???
it certainly won't break any sound barrier anytime soon, view it as a scaled down simplified but with a similar concept to that of a jet engine, because what jet engine is it's basically a bunch of high speed turbine sucking in air from the front, pressurize the air in the middle, and combust it with spraying fuel as the air were being forced out at the rear at a very high velocity, thus achieving the speed of sound. believe it or not, the concept of a jet engine is actually simpler to understand than that of a regular piston engine which a car uses, because it really is just a bunch of giant fan and some pipe that spew out fuel, the rest is physics.
At least Efforts taken Truly admirable here as above who does this in slums as we hear background noise in a country like India ,for Aeromodelling enthusiasts and other scientific platforms there is little or no space at all, only the glamour, rich and mighty with little or no knowledge, or interest just pushed in for photo pics..Thanks to this lad implementing his soul to the tech world.

This video at least gives you the idea that there are compressors, fuel supply, ignition and combustion chamber in a jet engine. I liked the video
You made a cool lighter, that jet engine title is just misleading

Thank U Jesus !!!
In the beginning of the video, when I saw he was super gluing the little metal beam to the cylinder, I thought wow! That glue must be top tech that can resist jet engine heat! 😐
25 years ago before model jet engines were available commercially, folks were making them out of compaing gaz containers and using VCR head bearings. Someone was machining the compressors and selling them at flying events. This was pretty clever, but I doubt it can produce useful thrust.
Engine=thrust
No thrust =no engine
Guys stop being rude, it might not be a jet engine but you don’t have to make fun of it, and what he made is an experimental turbine engine that a company made then they scrapped the project.
Colin Furze does some mad things with home mad jet engines.
Colin is way better that this kid, he makes the a jet engine bigger than a real one, and hi make it in his home
Colin is better
Up
Irrelevant, this is a mini model of a blow dryer
Very interesting! With some refinement, I can see that someone could actually make a crude, but workable jet engine like this a better than a toy!
Err ... I'd call this a fan blowing lighter fluid out the back of a tube. It might produce barely non-zero thrust because it is basically a simple afterburner. The jet engine itself is missing, there's an electric motor with fan blades instead. All that being said, I liked this video!
Good one 👍, try making the glue and spacers heat resistant and put them in fan- flame tube- turbine arrangement. You will have a real jet engine.
I thought this was going to be a functional turbojet or something.. oh well it's a start. Got to have a compressor with tolerance so that proper compression takes place without pressure loss through intake, etc.. I define the jet by it's ability to self sustain,only use electric to start it up. I'd start with an old turbo or something.. I'm currently dissecting a Dyson for a small compressor wheel.. it is a start though sir..
OK, this is not a jet engine. But he had fun, and this is exactly the kind of thing I used to do when I was a kid. I didn't know what I was doing but I did my best, and learned a lot along the way. Eventually I got into the design and engineering of building systems. Kids, learn how to build things with your hands!
Second Video named " Windmills powered by Brushless motor"
It's not even a brushless motor
I don't know when the definition of Jet engine had changed.
Next video: DIY Dyson Sphere for kids craft project
Would make a pretty cool afterburner for a ducted fan. It looks cool as heck but doesn’t really produce any real thrust.
man, a jet engine is not so easy to manufacture, but if you had made a combustion chamber not between the turbines but between them, maybe something would have happened
We can build it Wait... not between them but... between them? What?
@@yellow13_ that google translate
He said not but yes
When I was in school, I also made a jet engine based only on pictures from magazines, when there was no Internet yet, I did the same as you, for the sake of interest)
The title talks about making a jet engine.
Me: sees cheap galvanized metal, goes to click out.

JET ENGINE! in ur imagination!
Reality, gas stove powered by motor.
Wow, 10 seconds jet engine in a 12 minutes video 😱
do you expect an fully working airplane running in lighter fluid?
At least a good attempt. A small step to towards realising a big dream ❤️🙏
I built one of these in my 11th grade physics class. I had the VoTech school make the outer casing and my art department fired the compressor blades that I made out of clay. When we tested mine and used the after burner which moved 20 % of the fuel to the back, it tore off of the stand and went flying down the parking lot. It broke 2 10,000 pd bolts by shearing them off. I got my A in Physics.
Holy shit this is how it's done 🤣
Good job that's so cool!
That sounds so cool! I wish that I could build something like that in my physics class
Congratulations, its a turbo fan? maybe a over complicated torch? Idk but its cool
Nice stove ❤️..:
Not an engine but still looked pretty cool I guess
(Edit spelling)
Exactly
definitely the right concept. as for how much thrust this particular engine outputs though....
damn son you know you're making the absolute most of that itty-bitty bottle of Super glue!😁
Great effort and creativity in trying to explain a concept, Although not very accurate on the working principle of a jet engine .. Appreciate what you have done. Cheers.
What concept is he trying to explain?
He said JET engine not motor controlled.
This is not jet engine my friend. . . You made a blower for the fire.

With a proper nozzle this thing is a monster
this ain't a jet engine, although in fairness you did give me a few ideas there to miniaturize stuff, with a few mods on this design i think i can make a true mini jet engine. if nothing else, this design can take out a single robber's face if correctly-placed by the door at night (weapon of opportunity from household items; don't laugh at a steel spoon for being a steel spoon, in my hands i can stab that into someone's jugular or carotid attacking me while i'm eating), he'll still be alive, but now he has a real problem in his very face, his painful broken face is now his problem. thanks dude.

Cool
Only thing super about this is the glue. I hope it is high temp.
But still good to watch small things being made.
Very professional using some super glue to construct a "jet engine"
Jet engine should suck&burn fuel between rotors to initiate a chain reaction.
Yeah this just sucks! 😝
NASA should learn something from this video...
Absolute waste of my time... 😧 Jet engine..... Sure...
I agree
royjeuring you try making something off scratch and uploading to RUclips
It is just waste of time
It looks like an afterburner without frame tubes without a jet engine
Efforts are truly commendable than doing nothing..God Bless 🙌 such Efforts 👌
Very nice you did something from nothing! You shold try to redesign it do not listen to any one they expect to see titanium fans and other hi-tech things that they can't rebuild
Outcome : 3 lighters , and one a4 size of steel foil wasted .....
Thechnically it's a blowing torch with a blowing turbofan.But it's cool.
Now make a small time machine so I can go back and tell my self not to watch it.
I can imagine an aircraft with a very long cable to the power supply.
When I see it work without the electric motor connected to it I will believe it. 😂
"Jet Engine" ? I just smile

Wow, a multi-fan butane flame blower. Functions nothing like a jet engine.
Title should be "How to possibly start a fire and hurt yourself"

Actually this is a Prank Video
Creativity has no borders, language or nationality, criticism ,jealousy and mediocrity’s make your own limitation, congratulations my friend
"Jet engine" my ass! First, there are rotor stages, but no corresponding stators. Second, the rotor "stages" don't compress the incoming air. They merely accelerate it. Finally, the continued accelerated combustion of the butane is reliant upon the electric motor. If this were indeed a jet engine, a set of turbine stages being turned by the expanding combustion gasses would draw in air trough the compressor stages and sustain the combustion in the burner "can".
This is about as much a "jet engine" as lighting a fart.
He almost set that thing on fire..🤣
He used an electric motor to turn a couple of fan blades to blow a gas flame. Not even close to jet engine. What a fool
can yall fucking chill out godam i would like to see you do better with the same tools and money he had
@@crunchysoup406- Nope. This isn't a jet engine. It's a fan blowing flames. I admit I couldn't do better with he tools and materials that he had, because jet engines are so precise that making one needs more than the tools and money he had.
