Project help needed- Turbine engine

Hey Guys,

Fall is here and the drag engines are coming in for freshening and all. Needless to say, all the client's free cash is not being spent until Tax returns hit the mail so I am starting my project that has been a "to-do" for a while but I am in need of some subject matter experts or someone who has military or civilian turbine engine experience. I started this last year and it's been in the corner of one of the buildings. I am building a golf cart with a small turbine engine from an GSU/Huffer and I am not at all familiar with this platform. I totally understand the dangers involved. I want to convert from shaft drive to thrust with afterburner for show only (This is not the cart that pulls my dragster around from the pits and shutdown lane!) It will be painted and marked up identical to my puller but only powered by a rear mounted small turbine (Sun Solar or similar powerplant) This will not be shot down the track it's for show only(fire show and noise, minimal forward propulsion). I am pulling the engine and fuel tank to make room for the batteries and fuel cell and pumps. I will be putting Wilwood brakes on all four wheels and a weight box in front as well as a spare halon system from one of my wrecked cars (A few died this season) I will be fabricating the mounts out of moly and box tube (I have a good chassis welder- she is one of the best I have seen) That part is tackled. The engine is not. I have sources on buying the engine but do any of you have suggestions on where to look for a "how to" on the operation and thrust conversion for this doohickey? I saw some bar stool with a jet engine but the owner was a total prick and would not help. My friend who raced jet dragsters passed away last year and I am full of inspiration but I don't want to make an IED on accident. I will also be building a test stand for this. I see them on several projects via Google but no info. Any clues gents? Also any resources on finding a cheaper powerplant would be appreciated----- Iggy- see any at auction?

All the best,

As this is for show, a pulse jet may be better as it is louder. Perfect AMC project as it has minimual utility [bug fogger], and is loud and obnoxious.

hope these are of help/interst and let the group know/see what you come up with.

You should check this out, this guy has installed a jet engine in a VW Beatle.

Hey Rob,

Have a peek at the stuff on YouTube....such as:

Have fun. Take care.

Well, these small engines don't produce much thrust, you may not be able to even break static drag unless you change your golf cart to use bicycle tires. I think people have gotten something like 60 - 80 Lbs of static thrust out of them for microplanes. The GSU/Huffer engines don't generally produce much shaft power, anyway, just enough to turn an aircraft generator, so that's about 12 Hp. But, you have to load the power turbine, or just lock it in place, or it will overspeed and burst. Some of these engines the power turbine can be removed easily (and some of them don't have a power turbine as part of the basic engine section, it is just the gas generator.) Most of these engines don't have a throttle, all the controls are automatic, so mostly you have an on-off switch (assuming you DO get the engine control). Without the control unit, you would have to do a lot of work to even start the engine.

Nice reply, Jon. I think you let him down gently. The idea of using a gas turbine in a drag racer is almost as bizaar as the troll that wanted to put a steam engine and boiler in his pick-up.

RDF, I have never seen any turbine powerplants on auctions, never ever. A good issue of thrust was raised. I would love to stop by and have a look at whatever you are making when you have something of interest.

The big problem is that he's looking at it the entirely wrong way. He want's a turbine powered golf cart based on a turbine from a GPU... well, DUH!, that clearly points to turbine electric. Keep the turbine / generator combo from the CPU intact and use the generator to power the golf cart. For the afterburner effect, just have an ordinary auto fuel pump feeding an injector spraying into the turbine exhaust stream. Forget about useable thrust.

Duh !, indeed. The Pennsylvania RR came out with a very large, very powerful, turbine-electric locomotive back in the 1940's. From what I've read, it was only marginally successful. It basically only proved that "turbine-electric" is practical only in very large packages such as steam ships, etc. "Forget about useable thrust" is a good idea, esp. in smaller power plants.

successful. It

packages such as steam

It would be more successful today with better battery technology. In batteryless form it doesn't work real well since the turbine likes to run at a constant output level. With a suitable battery bank, a smaller turbine can provide the average power demand. They have a non turbine version of this as a yard switcher engine now where it spends a lot of time idling and recharging the batteries for the next use.

The OP's project of course doesn't care about efficiency. Just let the GPU turbo-generator provide cart power, and spit some useless flames out the back end.

An idea borrowed from the boilerless, compressed air locomotives of 100 years ago. No ? Call me old-fashioned but I don't see any modern innovations on the horizon that promise to contradict the immutable laws of thermodynamics.

Not a lot truly new these days, mostly just improvements on existing items. Still greatly improved operating efficiency for those yard engines from the old regular diesel-electric engines idling their big engines for hours between full power uses.

Ok. I start charcoal for my grill in a chimney starter... using a leaf blower for forced draft :) Try it at night, you'll like it.

I don't know about cheaper, bit I have seen APU's and GPU's as well as raw turbines for sale on ebay from time to time (I don't look that often). They are still in the real money category. I would suggest watching the government surplus sites. I used to be in the surplus business and saw a GPU's go through.

Good Luck, Bob

Some use 5 pound coffee can (metal) and a water pump pilers. Using a leaf blower is cheating. Gets a fire going before a beer is really started.

(Always soaked in lighter fluid in another 5 pound with a bottom.) dump into open ended sitting in the BBQ. Light, has draft - wait, then pilers out the can.

Has anyone mentioned "rolling your own" turbine engine using a junkyard turbocharger?
