Sure would like to eventually tie about 500 hp to the front of my rocket.

Do I hear 550?

There is no way to make a high bypass turboprop! And a late design high bypass turbojet only mixes fuel with about 20% of the air that passes though it, and in reality it is a "ducted fan' engine. These are not as efficient as a piston engine with a prop, but far exceed a turboprop. I noticed in the Innodyn articles that I saw published, that no fuel consumption figures were included. (or only that it would burn about 10gph at very low horse power.) Fuel equals power, and with Jet A costing more than 100LL I believe that 500 hp would cost 40gph or more. A friend of mine has a Walter Turboprop (725 HP) on his Sukhoi 26 purely for vertical acceleration in his air show. He talks about fuel consumption in cruise flight of 46 to 48gph. Having said all of this, I just love my Lycoming IO-540 C4B5. I had the injection nozzles "tuned" by Don Rivera of Air Research Inc. in Spartanburg, and my cruise fuel consumption is 9.2 gph 53% power, smooth as a turbine, and the Rocket goes 186KTs. When I want to pay the bill, it goes the "N" number at 13.6 gph, 75% power. I believe I can climb to 7,500" on less fuel (2.5 gallons) than a turboprop uses on a long taxi out. Sorry, but the greatest minds in the world tried every source of power plants (i.e. steam, electricity, chicken manure, etc.) in the 19th Century, and all came to the conclusion that internal combustion engines "do the deed." Thanks for reading my diatribe! Be Happy! Go LYCO!

I thought (perhaps there lies the rub) a turboprop is nothing but an extended high bypass turbojet. The air doesn't pass through a duct but the principle remains the same. With variable pitch and other fancy stuff that a prop can do they still determined that a high bypass turbojet is more efficient than a turboprop? (It will be at high speed, I guess, but otherwise?) I ask because I don't know.

It's off of a Pitts S-2-B, so the spinner may be different. There is also a 3 blade Hartzell and a 3 blade counterweighted blade MT propeller on that page, also.
