  • Won't you need an internal ignition source?

  • how much is it? where can i buy it?

  • 1:31 boom in da face

  • I think it would be worth trying to turn it over with compressed air as suggested by someone else and using butane as a fuel. You could try igniting it using a sparker held in front of the intake. The sort of thing you light acetylene with. This is how they used to start up the early model jet engines. Have a fire extinguisher to hand! Best luck with your amazing efforts.

  • Lol have you tried measuring the thrust

  • nice work

  • Puffffffff

  • your doing it wrong

  • excellent teaching aid -great video

  • Comment removed

  • Houston, temos problemas!

  • I have the urge to put somthing like this on a small car that we're making in my science class...But purposely rig it to catch on fire :3

  • I love these things!

  • Looks like a noisy lighter that doesnt function properly

  • You actually get what is known as a shock diamond. That's kind of impressive.

  • Awesome!!!

  • THATS AMAZING

  • So how is this a jet engine if an electric motor is turning the fan and moving air through and your simply lighting whats coming out the exhaust.

  • i know this sounds silly, but that little engine looked kinda cute

  • Can you please put a schematic of the inside workings of it? more like a blue print? I'm really interested in this. Thanks in advance!

  • You would also need to ignite the fuel inside the engine... or from the front... lighting the fuel vapor rolling out the back isnt going to help.

  • This is propelled by an electric motor and it's just burning gas. Not a jet engine...

  • External combustion.

  • I just don't think that little jet will ever work, but it sure makes a nice blow torch.

  • Just a noisy lighter

  • All you are doing is lighting the fumes coming out of the back. There is no way the engine will run that way. You need to get a spark inside the engine! Good luck!

  • u built that?? thats amazing!!... unfortunatly i dont have a machine shop to build something like that... nice work =)

  • Hey, i am no jet engine expert but i think that the electric motor will prevent the turbine from axelerating when it ignites, what i think you should do is to use compressed air, in that way the turbine can spin freely.

  • @hanheeer only problem with that is, because the ignition system is from the back chances (might work but chances) are that it will prevent the flame from burning back into the combustion chamber

  • You have very low speed from this electro starter, to start so small jet engine you will need to rotate turbine at about 360000 rpm to get optimal compresion to start engine. :)

  • loose compression?

  • How much will it be to get one from you?

  • Can it light a cigarette?

  • dude ive seen loads of gadgets,,, i would buy this kit... mass produce dude ? im amazed how small it is,,, smallest ive seen, i will now search for smaller though :)

    good skills

  • Dude, this is simply amazing! I'm so impressed that you almost made this tiny little think work properly. Excellent job :D

  • Fancy lighter you have there ..

  • put on a RC-plane :p

  • That is the most adorable jet engine ever.

  • more of abutane space heator

    

  • Cool model. Though your obviously an expert, my suggestion for startup would be to put a wheel on one end, and use a variable speed dremel with the sanding drum attachment (but no sandpaper) pressed against the wheel on he turbine. Then use a butane lighter or butane soldering iron to make it a one handed operation. Sure would be neat to have a tiny r/c jet powered by one of these.

  • that electric motor you were using to start it has way too much friction in it to get that engine started... should've used compressed air

  • The electric starter motor is the problem. Its spinning too fast and the flame is on the outside. Even if you spun it at the right speed, the magnetism in the electric motor would be working against the torque created from the turbine at spool up, thus, it will never spin on its own. If you got a very small electric motor, it might work.

  • Neat..!

  • interesting combustion like a toroidal doughnut, might be worth further investigation

  • Now we just need hamsters to fly that thing.

  • i dont think you should use butane, i would recomend diesel for a tiny engine like that.

  • Use a tiny bit of compressed air to blow the gas out of the exhaust , then light it , turn off the air and the flame will shrink up into the combustion chamber ,, then spool it up.

    That's how I got mine running without an internal ignitor.

  • hey that electric light you have in you hands... take the ignitor out of that lighter and wire it into you build.. for the spark.. if you are just lighting the gas on the outside with it all you have their is a fan blown cigerate lighter.... you need to lite the gas in the chamber not the exaust outlet!!!!!!!! hook a ground to the spring side of the clicker.. and have the tip of the spark shooter for the clicker near the ground...... and lets see you wide up that little turbine...

  • Needs longer combustor??

  • I think a better way to start it with compressed air instead of the electrical motor You use.

  • So, will it work WITHOUT the electric motor?

  • ther's a lot of friction inside,,, and i think you should get better fuel

  • @BreakingBucharest1 I know that it sounds like the rotor barely rotates, but beleive me it's because of the electric motor.. Without it, with a single spin by hand, the turbine rotates for more than 10 seconds..

  • @BreakingBucharest1 agree I mean you gotta be kiddng use atleast High Octane!

  • I know its a static model, but you can get those air powered pencil-style die grinders for cheap, and some are rated for 500,000 rpm. They have low torque. We use them to radius and detail tooling. It would be interesting if nothing else. Can't vouch for the safety of such a starter setup, but in case sometime you're bored. Fascinating model and machine work you have done.

  • @arnold02000 Thank you. Actually that's not a bad idea, because i had in my mind the dentist's drills that use air turbines, but they must be much more expensive than your solution.. I might try in the future my new microturbine that i made as a starter, it spins pretty fast so i guess it should work..

  • @arnold02000 I made a typo. It's supposed to be 50,000rpm with more expensive ones around 100,000. There are used dentist drills that have the 250,000-500,000 range though. When you think about it, air powered drills and grinders use turbines like yours, so it might be possible to spool yours up with a high pressure air port or throught the intake. Even a cheap walmart die grinder goes to 25,000. Something to try sometime if your curiosity gets the best of you.

  • looks like the propane is just too fast. you should rework the combustion chamber. make it wider.

  • if you make two that work i will buy them from you! but they would need to have decent thrust

  • This is verry sophisticated cigaro lighter no the jet engine

  • it*

  • @johnnyq90 I Really think you should TRY to make it work, i could be really cool

  • Any luck in getting it to work yet?

  • @Zappyguy111 To be honest with you i'm not trying to make it work, because it was not made to work from the beggining.. It is just a static model.. The reason i made this video was due to a lot of people asking to see it work.. Anyway thank you for your comment and merry christmas!

  • @johnnyq90 hey how much thrust does it put out

    

  • you should pre heat the butane, so when it comes in contact with the air it egnites instantly.

  • you cant just scale down a turbojet. it needs to be specifically designed to work at whatever displacement it is. air is more viscus the smaller you go and the laws of fluid dynamics need to be applied to a design to even make it viable in theory.

  • I can see this been used by the ARMY in future drone planes.

  • Looks not easy to work.

  • doesnt matter what fuel he uses it just wont work. you cant break the rules of physics!

  • To make a turbine like this work at 100% you need to use heliun or hydrogen gaz.....

  • @MsMartinsguilherme helium as fuel *pffffff*

  • Well i see that you understant of fuels, by the wey i was joking, but i think the most powerfull gaz is hydrogen ...

  • ive seen dozens of working homemade turbojets and turbofans and in one case a turboshaft built from plans for a heli. all of these engines were 6-7 inches from compressor to turbine and ive seen a few small jobs like the colibri. They dont get smaller without sacrificing practicality!

  • and I realize it must be started with an outside powersourse but a starting motor cant stay directly connected to the shaft. even if it could start to fire up. that elec. motor deffinately woulnt spin fast enough would need stronger one geared. and what about bearings? lube system??

  • but dont get me wrong. this is an awesome model.

  • @harrier331 a new engine bulit by chinese scientists at a cost of 7million is twice the size and spins at 700000rpms. m.i.t. engine on a chip is 1 square cm and if it would have worked it would have ran at 3million rpms. the smallest commercially available engine is the colibri(size of a pop can). as engine size decreases it must spin faster to maintain combustion this is the hurdle that keeps them from getting smaller. do some research yourself.

  • rpm?

    

  • that model engine cant function even if it has little combustion chambers and its perfectly to scale. you have just made a fancy lighter it will never run under its own power(notice the electric motor spinning it) it wasent designed to. a turbine engine that size would need to spin at 1 million rpms to sustain. simple physics, read up on how jet engines work. I mean you diddnt think that ten dollar keychain was a real jet engine did you?

  • @AndyTrampke listen you idiot this isnt a keychain watch some of his other videos he built all of the parts himself to scale it also has a combustion chamber a flame holder and a compressor ring the electric motor was there to start if if you read up on rc turbines you would realise that they need an electric motor is needed or compressed air to start it and all of the bullshit you were talking about having to spin at a million rpm how could you possibly think that

  • 0.5 hp... ill take 1500

  • What you need is some liquid gas for it. Regular lighter gas will not be sufficient enough because with that little DC motor, too much air is going in and not enough gas. Also, for the combustion chamber, you need more little fans all along the main stem of the engine. The ones on the front and back are good, but there are hundreds more on a regular scale model throughout the whole engine.

  • you're doing it wrong

  • Nice effects!

    The noise is principally due to the dc motor I think.

    Good job but a little dangerous.

  • if you want any (major) propulsion, you're going to have to increase the air intake somehow...

    and watch the fuel/oxygen ratio, youll blow it up

  • Could be easier to put the turbine aside and let the e-motor do its work properly...

  • @Firelwithoutlwire - I think this is the key reason it would not fire. No air compression. The while he cut slits into to make the compressor blades would not actually compress the air. Maybe with more stages it might work.

  • actualy this could be a nice invention it look's like a very efficent lighter

  • I see shock diamond? But what the purpose when your starting motor would have more power than this engine.

  • nice lighter that has to be lit by another lighter

  • why dont use a highspeed brushless motor?

  • Yes, if only everybody had one, there would be no more war, no more worrying about anything. We could all lie in, no more work etc. 

  • boy its a good thing real jet engines don't need an electric starting motor that big!

  • Hmm. You should stick this on a small toy car (Probably would be small for a R/C

    car, but if you remove the propelling electric motor, and instead connect it to a throttle

    control solenoid (You would probably have to fabricate, but it seems you're already good

    at that anyway) and keep the steering circuit, you could make the world's first small R/C

    car powered by a jet engine! (AKA JATO toy - and yes i know this is not a jato rocket,

    just a catchy name for a car powered by a jet engine.)

  • Great model. I don't get how people are still commenting on how this isn't working properly as a jet engine, considering you built it as.... a model. I think it went above and beyond since you plumbed it and everything.

  • wow

  • Keep in mind that your reynolds number must be consistent with the scale of your model/engine/anything!! Smaller you go, the faster it needs to spin! You should get a really high KV motor from hobbyking for cheap! I'd say 3200kv with a 4cell lipo battery,

  • Woah, thats awesome. This is how sniper bullets should be propelled xD

  • the electric motor is powering it

  • its so cool its almost cuta haha, nice job!! atleast you got flames from it

  • but seriously, really cool idea

  • aaaaaaawwwwwwwwwww, it's so precious.

  • Combustion on the OUTSIDEof the "jet engine"? Sort of like a cigar lighter, eh?

  • I know you didn't aim to make it run but I think that perhaps if you started it by blowing compressed air into it, it might actually run. I'm no expert though haha, just something you could try

  • that was kinda like a jet with no jet engine just an after burner

  • The future car engine, only 600 of these and you will start going...

  • rpm ??

  • Nice work! I love the concept and your ability to use a dremel!

  • have you tried blowing compressed air through the compressor inlet?

    that should give you much more RPM to try to go in sustained operation.

    The flame ring at the nozzle looks pretty uniform, nice!

  • U should blow compressed air in it and see if itl run

  • @johnnyq90 Normally, the fuel would combust at the head or inner chamber and make enough thrust and heat to keep it going without the help of a motor. You should look in to this.

  • o thare is a test haha.

  • Ha! that's awesome. Imagine that on a tiny Batmobile.

  • can it operate without the external motor??

  • does it create the thrust??

  • you could fit it to a 747! :D

  • epic..!!!

  • Awesome !work I am a big fan of stuff like making rc models for the real and big engines so I am just wondering would a real jet engine has a motor running infront all the time or just to start what was the real process?

  • -hahaha, it's not a jet engine,it's a lighter.you're just blowing off a lighter fluid, hahaha

  • only one top comment.. nows my chance!!

  • @bugaboy02 youll have it when you contribute somethign regarding the video, and it stays top, youll be there for life Eh? lol :P

  • hav u thought of running it on hydrogen

  • wow......

  • that thing would make a cool lighter! XD

  • How many pounds of thrust?

  • what can you do with it?

  • get the marshmallows!

  • time to put this in a paper airplane

    =D

  • Can anyone help please! how big a jet engine is enough to lift a 140 pound person? please reply!

  • @Celis215 i think 2 one foot long jet engines

  • @SpetsnazHell thank you very much! anyway, I've discovered the pulse jet engine and it has stronger thrust and better cuz it does not need fuel at all.Just a good craftmanship. Anyway, thank you!!!!!

  • that'd make a pretty awesome lighter lol

  • you should hook that up2 to something to measure thrust, maybe susspend it from lighter springs n see if it moves

  • can it use to fly tiny rc jet?

  • Super lighter! that's awesome!

  • Great idea, but you have to have the fire burning in the combustion chamber, lighting it from the exhaust end will do no good. Keep trying though.

  • I took a dump about an hour ago.......it was nice...very relaxing.

  • Not quite a jet but it would be a sweet crack lighter! Shit, now I'm jonesing for an 8 ball!

  • You need to install a glow plug in the engine so it will ignite inside the turbine.

  • I want one for my park flyer.

  • That is not a gas turbine engine. It's a DC motor powered blower with a fuel inlet so that it burns at the end. My Bernz-O-Matic propane torch does the same thing... without a motor. Cute video though.

  • Jet engine?!! Why then does it need to be powered by an electric motor? It's a battery operated flame thrower!

  • It might work better if you use a high quality high speed electric motor, instead of this cheap motor with poor bearings. This ia a cheap Mabuchi. Try a more expensive Mabuchi: RS-755VC/WC or try the RC-280SA . These motors are more up to the task and have better bearings. The small one you are using now will soon melt under maximum performance. Just a hint...! ;-)

  • secondo me dovresti pre-riscaldare il metallo del motore, altrimenti la fiammella si spenge mentre le ventole girano a freddo.

  • you need to use hydrogen.:)

  • you need to get ot at least 250000 rpms for it to lite and run (just saying).

  • i really like wht you did, thanks for sharing it, if you wanna increase the compressing ability for better combustion you should you static rotors and makes stages of compression . static rotors in a diffrent angle of attack can be attached to the casing .. good luck

  • What the fuck? This is NOT jet engine.

  • thats no engine. its a very loud bunsen burner.

  • You need a better fuel source so the engine can be self sustaining

  • Too small to actually provide useable thrust because air molecules are much too large for this to intake. That thing's also gonna melt eventually.

  • Too bad it didn't work...

  • I think, if this will be little bit bigger not more, just a little, this will work!

  • Fantastic project! Tempted to have a go :) Did you use photo-lithography to make some of the parts? (No probs if you're fed up with this and want to move on, i'm just curious).

    All the best to you.

  • @NuguSmedley Thank for your kind words.. I didn't use any high tech method to build it, just some regular tools.. The most complicated tool i used, was a dremel rotary tool ;)

  • @johnnyq90

    In that case you must be a master with the dremel!

  • @johnnyq90 can you send me some sort of instructions on how to make this PLEASE

  • @johnnyq90 but how the hack did you get those comppressor wheels and vanes done with some easy tools :O?

  • That's fuckin' mad man

  • Very nice work so far, but I dont think the combustion was happening in the combustion chamber, but at the exhaust. It needs to burn before it hits the turbine blades, or else you got yourself a gas burner, not a jet engine.

  • @misium That is what I was thinking myself

  • @misium indeed, this was nice but it wasnt self propelling or self lighting, it was just burning gas

  • nice lighter

  • Now all you have to do is complete some tiny jets train an army of aints, and take over the world!!!!!

  • put on a office chair :D

  • does it produce thrust?

  • EPIC!

  • @json2040 Thanks!

  • @johnnyq90 is it me or did it actually kick in and work for a short while? This is pretty cool :)

  • you seem to be having trouble with blow outs, perhaps a better flame holder? is there even one in there?
