You need to reduce the size a bit:

QuoteThat looks like some good work you did there. What type of applications are you planning on using this for...other than making your house smell like jet fuel.
You could use it to get TrophyHusband's siphon started.

Here is a website which goes through testing procedures etc of one which he built. It might help you out with your problems http://www.powerlabs.org/turbine.htm

Well right now it is just a test stand engine, my oil pump and ignition (a ballast for a neon sign, works great!) both run on 120v, so I would have to convert them to 12v to make it mobile. Some people put them on go carts with decent results.
My turbo is fairly small, and I only expect about 10-15lbs of thrust, which is barely enough to drive a vehicle of some sort. Some of the larger turbos like the ones off of Mac trucks can produce much more power, but they cost a fair bit.
I just tried running it again, using the exhaust from a in house vacuum, which provided ample thrust. Unfortunately, it wouldn't start, I think I have a problem with the combustor or something, I am going to remove it from the engine and test it by itself, to see what is up. I may need to make a new injector, or modify the flame tube.
Regardless of troubles, it is still a fun project, and should make it that much more rewarding when I finally get it running.
Thanks for that link, lots of good info!

I am wheelchair bound for the next month, after ankle surgery a few days ago. A few of my friends have advocated that I attach the jet to my wheelchair, although I think steering would be an issue hahaha.

"Friends"?
Maybe they are telling you something!

Meh, steering is overrated.
It's a jet, right?

This is So cool - nice work.
Have you tried different fuels? .... Bio/recycled cooking oil etc,,,,? What works best? .... Can you start on one fuel then switch to a different one?

QuoteHow much thrust do you get out of it?
Screw getting any thrust. Getting the thing to run, even slowly, is a win.

Success! I got the thing running tonight. It sure makes one heck of a noise. There was an issue with some pulsing, I think I know what the problem is. Inside the flame tube, one of the holes that allows air into the center of the combustor is right next to the main air inlet, and I think that it is causing some flame front problems. I will weld up the hole tomorrow and try again. Also, my fuel regulator only needs about an 1/8 of a turn to get about full throttle, so I will install a needle valve instead to get better control.
I am running on gaseous propane, but a number of liquid fuels are possible, including liquid propane, diesel, kerosene, Jet-A, etc. Propane is the easiest, because it quickly vaporizes, and doesn't require a fuel pump. I may try other fuels in the future, but for these early stages I would like to get it running well on propane first, before I make it more complicated. Afterburners are usually run on liquid fuels, and I would like to put one one eventually, so I will be looking for a high pressure pump sometime soon.

You should get started on your engine! This thing has been allot of fun. I am using an oil pump from a Volkswagen bug, because I had it laying around, but I hear that power steering pumps work well. The pump I have doesn't have a seal on the output shaft, so I installed a O-ring and applied some gasket maker to the pump body where the shaft goes in, and it only leaks a little bit while running.
The oil system has been the biggest issue, everything else is pretty simple. I built the combustor out of steel, the oil tank out of a paint can, bought an oil pressure gauge from an auto parts store for about 25 bucks, and used a tire pressure gauge for the inlet pressure gauge.
About running slowly, these things haul ass! Even a slight increase in throttle makes that thing start really accelerating, and produce lots of heat.

Still no pictures or video? Yer slippin!
Here is one for you from last night. You can see the glow of the turbine blades, they sure get warm.
I should have my flame tube rebuilt tomorrow, and I will try to run it again tomorrow night.

I'd rather play with the buel in the background!
Me too. Why do you think I needed ankle surgery?
