This is a run-up of my home built turbocharger turbojet engine. Long, but maybe of some interest to other engine builders. It is quite old now and dated somewhat and I now know far more about jet engines than I did then. Please go easy on me guys… It is my first video! I would like to issue a challenge to all fellow Do it Yourself Turbojet engine builders and brushless electric R/C park flyer hobbiests/manufacturers out there. Please comment and discuss the feasibility of mounting a small “outrunner” style permanent magnet brushless electric motor to the compressor side of this and similar engines. I realize that shaft harmonics and bearing limitations will play a very significant role in whether or not such a motor/generator combination would hang together at 140000 RPM or more. Of course, associated power electronics with the ability to switch from starter motor to DC generator would need to be designed as well to efficiently (relatively speaking) produce electricity at these ultra high speeds. Such a device would mimic some of the hybrid turbocharger or “electrically assisted turbochargers” that have been developed by Garrett and others in recent years. These have been designed, developed and built to reduce “turbo lag” and recover wasted energy in the form of electricity with the intention of supplementing the charging system in vehicles. They have not quite made it to market yet in any production vehicles that I know of. I am crossing my fingers! A hybrid …
@crafter2u once i bet
Why all the smoke on shutdown?
Congratulations for reducing radius of exhaust turbine wheel in seconds by burning it with excessive temperature. This is also common failure with these “science projects”. I have old disassembled Garrett T04 that I have planned for years for this kind of application, but haven’t had time for it… I was thinking about using diesel from the beginning. More difficult, but more awarding as well.
Will the combustion continue without continuous spark?
I can see you have a value to make the right Gas and air mixture, i got 2 questions.
How is it possible to give more power, like in a car when you step on the speeder
And also
The real Jet egnines is running on fuel, there is in lc, not as gas. How will you be able to make it run on lc fuel?
@SuperSwampfoot The problem is, you have to know what to do!! o.O
collect energy from it. propane is a natural gas
beatifull
put it on a scooter!
@willharris1000 yes, if there is enough heat and pressure. but i think it would gradually lose heat/ pressure and eventually cut off
@Aratixwrx Thanks ! Ill have to try it out and play with it.
Its on fire!!!
LOVE the smoke…amazing how much smoke came out from that thing
what amount of thrust would you get on something like that?
The best turbo vid ive seen yet. Very informative and makes things alot clearer for me to attempt my own project!!! would love to see more!! Thanlks
Anyone can post a video on youtube and boast about it,but its not everyday that i feel i’ve learned something by watching one.SIr,i salute you
Unlimited energy sources are out there!But the Oil coporations life depends on covering this up,Check this free energy magnet motor at LT-MAGNET-MOTORdotCOM ,Join the revolution!
please fasen your seat belts and prepare for take off
any idea how many RPM’s?
this is cool but there is no way this could propel an aircraft.. at least this size, even with a nozzle on the output
@Designandrew
A UAV, an RC jet. Space would have to be optimized, but why not.
@Jimmy81691 Because these types of jet engines made from turbo chargers are really if-efficient, and have a really bad power to weight ration, ESPECIALLY for an RC jet!
I cringed every time the camera man walked in the exhaust stream, hoping there wasn’t any mechanical failure on the fins.
@SmalltownTractors a turbo on a regular car, like the one he is using will have aprox 80 000 – 120 000 rpm. this is limited because the turbo propeller shaft has no bearings. oilpressure is making a thin oilfilm that the saft is gliding on. if this was a ballbearing turbo (often used on raceengines) you would see up to 200 000 rpm, and even more if things where optimalised. there have been recorded over 250 000 rpm on race turbos wich i know of
hope you understand 
@TheRsemil oh wow, thats crazy numbers, thanks, i had no idea they went that fast!
