This little engine has reliably powered the magnificent Bell Jet Ranger helicopter for over 50+ years and is one hell of a gem of an engine! So tough and dependable.
And the thousands of hughes /md 500's it also powered certain versions of the twin engine as109's it also was made into a turboprop tens of thousands of these were made
This little jet engine is an amazing piece of engineering. Simplicity and robust. Maybe not the most efficient in the world. But just a badass piece, my favorite. Would love to build a jet boat with this driving an impeller. As compared to most using a chinook 1200 -2000shp. I think the lighter weight and power would be great for a little 14-16ft boat. Or mini jet boat.
I'm just saying man, with vantablack being a possibility for someone to recreate I see a tiny AR500 armored cobra type RC helicopter of doom to be made.
Loved working with & running up this P/P in school. Have often thought about powering a riding mower for " mower racing ". Hell, if it will drive a bike, why the hell not??
No, not used as an apu, lol. It's a T-63 turbine. Made for the keawa oh-58 helicopter. I know, I worked on them in the Army... among several other types of helicopter engines. I served in an CH-47c\d model Chinook unit in Germany before the wall fell.
THE INSTRUMENTATION DESIGN AND CONTROL OF A T63-A-700 GAS TURBINE ENGINE .A T63-A-700 gas turbine engine has been instrumented to measure performance parameters. Pressure and temperature monitoring systems have been designed, fabricated, and installed to ensure accurate measurement of performance parameters. All measured parameters have been compared against predicted thermodynamic cycle analysis. Design and control of selected engine systems have been modified to incorporate more precise engine control and safety. All using labview and visual basic.
If I ever get to a point where I have a good amount of free time and a good stable job with a comfortable amount of spare cash, I'd buy a nice, little, lightly-used Rolls Royce 250-C20 and a barn find Corvette, preferably the C4 chassis, and I'd put the two together. Maybe see if I can get these future "blackfinger" hands of mine on a C30 or even a C40 if those would fit in the engine bay. Then of course I'd have to make a heat exchanger to preheat the intake so it doesn't drain the fuel tank in a singular minute, the C20 does have like 400 herspers while the C40 makes a cool 700 flaming ponies of fury. And the heat exchanger would be so I can avoid peeling the paint of the Lambos I'd leave in my dust, and a nice exhaust after that to dampen the noise so I don't reach like 20 tickets per hour of law-shattering momentums. I'm also tired so I might not be thinking straight XD
you realize what a big deal they make of the least little ding or dent in that combustor skin or those tubes on the side. They are supposed to leave the plant almost flawless. I inspected so many of these.
Know what I like about the Allison? It is small, light weight(about +\-200lbs), and it has the necessary power needed to overcome most stall maneuvers."
Sir, I have a question for you. There are several videos of the Allison/RR 250 C turbine being tested on a ground stand. In such condition, the power turbine isn't connected to any mechanical load (transmission, or a test brake). Since the 250 is a free-turbine design, doesn't the power turbine overspeed - even with the gas producer at idle - when left unloaded? Thank you.
@avonaero1 - Question for you, I don't know much about the design of that. Is the shaft PTO a separate turbine that free spools or it is driven from a common shaft. Appreciate the info and thank you for sharing this!
If you can fit and secure it you can use it. No problem with horsepower because it can deliver easy. The one I was taught with put out ~420 shaft horsepower with some insane amount of torque. Weighs around 400 pounds.
Bravo..........is that out of a car..........for a demo world trade fair ........they ran a turbine on Purfum .......channel #5......I dream .....cheers
