Tiny jet engine test 1

UPDATE #3
Video of the initial testing of my little jet engine i made due to popular demand. Many improvements have been made in order to make it work better and look more realistic.
You can see in the pics, the front and back view of the combustion chamber. The diffuser and the ngv can be easily distinguished.
I must also mention that it uses two 2x5x2.5mm hybrid bearings. Always remember that my initial intention was not to make a fully working tiny jet engine, but to make a miniaturized version of a R/C model jet engine, so don't expect to self sustain... I know that you 'd really like to hear the sounds that a jet engine makes, but trust me with no calculations, nothing can happen..
IT IS NOT A WORKING ENGINE, JUST A STATIC MODEL
NO PLANS
NOT FOR SALE

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

[johnnyq90]

@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..

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..

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!

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.

I was hoping this would be a real combustion powered turbo jet. Still neat though.

Check My Video !! You Won't Regret to see my Turbine MINI !

HUZZAHS! You're quite an engineer...NASA could use your micro-tech abilities... going to Cal Tech or MIT in the near future?

@BreakingBucharest1 To me it looks like a blow lamp with a fan, I some how think the burning should be inside the thing not out the back being driven by the electric motor, Cheers, Pete

[JIZZZification]

whats wrong with the dynamo motor?

[givemetoast]

Great effort!!

@DestructoXxShaunxX

I did. It doesn't work. The electric motor does all the work. glorified lighter torch.

[TheSliekaStyle]

air/fuel ratio es wrong as hell with this fuel supply!

[jordan123089]

i wonder if its because theres too much friction for the turbine to spin the motor and whether its because the combustion is taking place outside of the engine. maybe if you can make an ignition system inside the combustion camber it'll work better.

Ok who disliked this, ill find out where u live!
