Thanks! The T04E clone cost about $129.99. We knew it wasn't the best to use an eBay turbo, but for what we needed it for and how long it'd be running it's been fine so far. We can now get the engine to reach a stable RPM very quickly, and can fully attach the shop vac when starting, aiding in spin up time. Also no more fire shoots out of the turbine at start up (although it looks pretty damn cool) because we know the optimal fuel dump pressure.
Mike, what are you doing for oil pressure? If the compressor/combustion pressures exceed that of the oil pressure you're going to end up with blowby in the oil system and bearing failures. It happens a lot with these setups. really cool work!
Hi Mike it is a very good design. Fast start up. I made the same system and finished about 6 years ago. I added 2nd stage turbine from bigger turbocharger and coupled it to the electric generator. The problem came when I changed the fuel from propane to methane, the nozzle must be changed to comply with the Air to Fuel ratio. Good luck for the next development.
The thrust is controlled by how much the fuel valve is opened. You should NEVER have glow in the turbine because this indicates that combustion is taking place too close to the turbine blades and not in the combustion chamber like it should be. You can see the turbine briefly glow during start up as the engine stabilizes. I'm not sure what goop you're talking about, if you could give me a time to look at.
Looks great Mike, I'd toss on an exhaust pipe if you haven't already on that one... Your combustion chamber is huge, maybe you might want to try a ST50 with and afterburner next?..Stay safe..
I made quite a few, been a jet engine mechanic since the early 80's..Your idea's are spot on, Play around, experiment. Don't just stop with the little guy there. There's HUGE AiResearch Turbo's out there for example, like a TV 7101. You cant get 70lbs of thrust out of it, well over 100 with an afterburner, go have some fun!!
Stanley, no we haven't. Although we may be able to get this engine to run on kerosene by using the spray nozzle injector. It's easier to switch to kerosene once the engine is already running on propane. Thanks for watching
Great work! I am working on my own engine but I've been having a problem with sustaining a flame inside the combustion chamber, I think the leafblower is just extinguishing, do you think using a vacuum would be better than the leafblower?
Thank you! We were originally going to use a leaf blower, but the shop vac set to "blow" mode had a lot more upmh and got the engine spinning quite a bit faster. If you don't have your engine spinning fast enough, it won't be able to successfully reach a self-sustaining state once the air supply is removed. So if possible, I'd definitely recommend using a shop vac. When it comes to your flame extinguishing, that might be a problem with the initial, mixing stage/ignition stage of your combustion chamber.
hello, yes it runs on propane. the size of the combustion chamber has to be large enough to contain the flame to prevent it burning up the turbine. you can look into a program called JetSpecs for guidance on your combustion chamber size.
As Ryan C said, it was an achievement. This was a school project for our senior year engineering design project. Plus it's a hell of a lot of fun to see your neighbors reactions when you first start it up!
The bigger the combustion chamber, the longer the combustion gases have to mix with the bypass air which will lead to a lower turbine temperature, and a lower EGT. Too big though will cause the engine not to function properly. I recommend a program called JetSpecs for help sizing your combustion chamber
+Mike Lipani no sign of smoke means you made a killer engine :). I have one question, are you using a high-pressure propane regulator for your fuel supply? I have built a turbo jet with what looks like the same exact turbo you used and I also made a vertical combustion chamber (what a coincidence!). I cannot get my engine to run with a low pressure regulator and I am running out of ideas.
+TheNosyGamer Hello! thanks for the kind words. We did in fact use a high pressure regulator. There has to be lots of propane flowing for this engine to run. Here is the exact regulator we used: Goss EP-70G High Pressure Propane Regulator, LP CGA510 with Gauge B Hose www.amazon.com/dp/B00D2ZVTZK/ref=cm_sw_r_cp_apa_SE4lxbQ3NAWD4 Thanks for watching!
Actually, it's just one turbo. What you are seeing is the compressor and turbine sections. Together that makes one turbo. Making an engine this way is not much more than taking a turbo charged engine, remove the engine, and replace it with a combustion chamber.
Philip, I don't think you even know how difficult it would be to manufacture your own compressor. It isn't cheating, because a turbocharger isn't a jet engine on its own.
Finally someone uses a decent sized combustion chamber

that is probably the most successful one I have ever seen
1:50 - that mattress is in better shape than my current one.

can you send me construction plz
i wanna build one

Very very very nice running cranberry clean I wish there was a chance to see the combustion chamber setup
Great work!
Thank you!
2:28 lol. Nice job, it looks cool
Lol, thank you! Not one of my best moments...
it is highly advisable to have a intake screen
love the start up flame wprks perfect
Thank you, we loved the startup flame (although it isn't the best for the turbine :P)
Looks great Mike, I'd toss on an exhaust pipe if you haven't already on that one... Your combustion chamber is huge, maybe you might want to try a ST50 with and afterburner next?..Stay safe..
+CaptAmericaUSAF Thank you! That's an interesting idea

nice....
Ignition starts at about :50 and for a full view of the engine skip to 4:40
what's the fuel flow like?
It’s my dream. I will make a jet engine.
Amazing!
Have you tryed a smaller combustion chamber with a spray injection nozzel and liquid fuel
Stanley, no we haven't. Although we may be able to get this engine to run on kerosene by using the spray nozzle injector. It's easier to switch to kerosene once the engine is already running on propane. Thanks for watching

***** Great, thanks for the advice!
+dariusz87 i have seen an air compressor blow gun used to spin the turbine up. that seems to spin them up very quickly.
Do you have the blueprints to make that turbine?
Does this run off propane and would running it off propane mean that ot needs a larger combustion chamber?
hello, yes it runs on propane. the size of the combustion chamber has to be large enough to contain the flame to prevent it burning up the turbine. you can look into a program called JetSpecs for guidance on your combustion chamber size.
+Mike Lipani awesome thanks
Why are you running got with the combustion chamber below the turbo? All your doing is fighting gravity.
So what do these do exactly, besides make noise and never power anything?
Avalanche2 they look cool, it's an achievement when you make your own jet. Plus u could power a battery like the apu on plane
As Ryan C said, it was an achievement. This was a school project for our senior year engineering design project. Plus it's a hell of a lot of fun to see your neighbors reactions when you first start it up!
So what you saying the bigger the combustion chamber the cooler your turbine is that it wont melt in the heat
The bigger the combustion chamber, the longer the combustion gases have to mix with the bypass air which will lead to a lower turbine temperature, and a lower EGT. Too big though will cause the engine not to function properly. I recommend a program called JetSpecs for help sizing your combustion chamber
Mike Lipani thanks......you by any chance you know how the acceleration and deceleration works
Why is there no exhaust fumes or no sign of smoke. Is this a sham or for real?
+David Hoover David, I promise you it's real. Did you see the flames and glowing turbine during startup?
+Mike Lipani no sign of smoke means you made a killer engine :). I have one question, are you using a high-pressure propane regulator for your fuel supply? I have built a turbo jet with what looks like the same exact turbo you used and I also made a vertical combustion chamber (what a coincidence!).

Thanks for watching!
***** Yes I still have a chance to make this work! Thank you SO much for replying. Great build!
***** Do you think that a 30 PSI regulator will work?
Now leach power from it to do some thing.
That's the goal. I will be hopefully be releasing a video soon about the revisions to the engine
so simple its just 2 turbo's
Actually, it's just one turbo. What you are seeing is the compressor and turbine sections. Together that makes one turbo. Making an engine this way is not much more than taking a turbo charged engine, remove the engine, and replace it with a combustion chamber.
You are exactly right!
y this shit not even move so that we say yes to it?
What are you talking about?
Using turbocharger = cheating
May I ask, but how is that cheating? They made a jet engine. Nothing more, nothing less.
Philip, I don't think you even know how difficult it would be to manufacture your own compressor.
It isn't cheating, because a turbocharger isn't a jet engine on its own.
