That’s not a fricking jet engine, it’s a series of fans blowing at a butane flame

the title should be " how to make a gas stove"

USB powered electrically blown dual tanked oversized cigarette lighter with external manual timber-sulfur type ignition. I believe that would be more suitable title.

Not even close to being a jet engine. It's a very poor electric blow torch.

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.

Whoah! This thing actually works. I glued mine to the back of my Toyota Corolla, and I got up to 250 mph! Then I ran out of lighter fluid.

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?

Nice, kids where I live are sucking on BIC lighters and making metal cones not turbines

1.2m views as of this post x 12 minutes is 27.4 years of humanity wasted.

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.

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.

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.

This is just a flamethrower and unfortunately not a successful one. I don't think you understand the principles of thrusting and engines.

Yeah sure. Let’s glue the turbine fans. Totally safe huh!

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.

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.

It’s just a fan with fire 🔥 😒

There's twelve minutes I'm never getting back.

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! 😐

I don't know when the definition of Jet engine had changed.

"At last. Marshmallow toaster is complete."

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

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!

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.

I knew something was wrong when the title said jet engine and the first thing he used is fevikwik....😆😆

That's not a jet engine, but still impressive and took time to make!

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..

Even though this video wasn't what I expected....It can't be considered a waste of time..Good jugaad👏🏼

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.

Come on guys, give the Dude some credits, this is a legit jet engine, working only on afterburners, he has the compressor, doesn't have the combustion chambers, has replaced the turbine with the electrical motor, he has the afterburner nozzles. You got to start from somewhere, the Dude is really creative, I'll give him thumbs up. Good job Man!!! After you study Thermodynamics and gas turbine cycles in college, you won't be that enthused to make jet engines.

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!

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

watch from 12:16 Thank me later for saving your time.

That was for a children to get the concept..... appreciate the kid effort....Bravo....

I'm skeptical that it's producing thrust though... It looks like a fancy torch TBH.

I like it when I got a video with the "How Jet Engines Work" title on my recommendation sidebar

You made a cool lighter, that jet engine title is just misleading

The title talks about making a jet engine. Me: sees cheap galvanized metal, goes to click out. This guy: *superglue* Me: *sits back down*

Random Iodine Namak advertisement in background 😂 Struggle of every youtuber in India

When I see it work without the electric motor connected to it I will believe it. 😂

Would make a pretty cool afterburner for a ducted fan. It looks cool as heck but doesn’t really produce any real thrust.

Yup it is an edf with a post burner ;) try changing the motor with a drone one, they're ac motors and they cost almost nothin'

in other words he could have just made a very simple flame holder to make it a whole lot more impressive

I can imagine an aircraft with a very long cable to the power supply.

more accurately called: "fire amplifier engine"

SUGGESTED TITLE : HOME MADE INEFFICIENT BLOW TORCH

The Sabji man shouting out side reminds me of Bhopal many years ago.

I'm so glad I skipped to the end... and saved 12 minutes of life.

Title How can i steal someone else's time? or This is a way to spend time when a person infected with corona is isolated.

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

definitely the right concept. as for how much thrust this particular engine outputs though....

Jet engine which works by electric engine, GENIUS

Colin Furze does some mad things with home mad jet engines.

come on guys ,its a young man having fun n hopefully young children will be inspired with some messing about crafts no need for the immature comments

That Background noise thou😂👌

Wow... May be not efficient, or useful at all, but still demonstrates the "jet" principle !

Second Video named " Windmills powered by Brushless motor"

The video should be named like "How to make a mini stove with mini fans in series"

Efforts are truly commendable than doing nothing..God Bless 🙌 such Efforts 👌

Cool, that's the first ever battery powered jet engine

Jet engine should suck&burn fuel between rotors to initiate a chain reaction.

Engine=thrust No thrust =no engine

that was amazing. How loud was that little thing? Looks pretty sweet. Drank that fuel quick!

"Thank you very much "I didn't thaught that this would be easy to create a jet engine

JET ENGINE! in ur imagination! Reality, gas stove powered by motor.

Why are the comments so negetive? I find this amazing

That is an just an Afterburner with no Combustion chamber. If you used metal spacers instead of plastic, and welded the pieces together instead of super glue, you can add in fuel injection ports between the fin pairs in the middle of the engine (Combustion Chamber) with their own fuel tanks (lighters) - not wide open like you did with the Afterburner fuel tanks. Then you run the motor as a starter as you ignite the Cumbustion Chamber fuel, then shut off the motor. The engine should run slowly on its own. Then if you press the Afterburner tank buttons the thrust will increase.

It actually works exactly like a jet engine. All he has to do is get rid of the motor, clip the fuel tank on, and throw it like a dart.

Absolute waste of my time... 😧 Jet engine..... Sure...

12 minutes of my life - Lost forever!

Be nice to see how much thrust that multi fan turbine produces. Electric jet basically

Better than the regular DC motor with a fan

Thats why i read comments first than start watching any videos 😂😂

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.

i hope he knows how much temp a jet engine reaches, that's enough to vaporise those glues and pretty much anything in it!

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.

There should be a compressor, combustion chamber and turbine. This is just an electric powered compressor, something that we could call a combustion chamber, but no turbine to spin the compressor. Please, take a look how jet engine works.

Nice stove ❤️..:

With an adjustable gate, you could tune the afterburner too 🤗

Muito bom Parabéns nota 10 Obrigado

damn son you know you're making the absolute most of that itty-bitty bottle of Super glue!😁

Wow, a multi-fan butane flame blower. Functions nothing like a jet engine.

Only thing super about this is the glue. I hope it is high temp. But still good to watch small things being made.

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!

If you clicked on this video actually expecting to see a real jet engine, I feel sorry for you. You should know by now that this stuff is never good.

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.

When i see oily skin and technical approach in video i first give the video a like than i watch the video❤

Hm, I think it is just an electrically driven fan burner. It would be interesting to measure the thrust without and with butane.

Outcome : 3 lighters , and one a4 size of steel foil wasted .....

It looks like an afterburner without frame tubes without a jet engine

You can make the engine bigger. The bigger the better (as long as it doesn't get too heavy lol)

Kompor jos . Yang biasa di pake penjual gorengan ..

"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.

Eu tava aqui triste ,mas parei pra assistir esse vídeo e até q me deu uma animada ,. Gostei do vídeo , não liga pra quem fica falando mal dizendo q desperdiçou alguns minutos das vidas insignificantes deles aqui. ...o vídeo foi bem legal , continua fazendo mais vídeo assim ,pois na vida sempre tem aqueles q querem desanimar a gente a desistir . é aí q as coisas vão começar a melhorar pra gente, pois quanto mais a gente evolui ,mas gente sem graça aparece pra desanimar a gente . Mas no final a gente sempre vence

That's an afterburner with no jet engine...can you make it self-sustaining?

最近有点失眠，这条视频确成功把我看困了，但我还是坚持看完了，万万没想到最后居然是自己点的火

"Jet Engine" ? I just smile
