What are you going to do about a reduction unit? How much fuel are you going to build into the aircraft? The ATP engine is based on a Solar unit as far as I know, and an acquaintance that worked there (not associated with the design) said that it is designed for long life, not low fuel consumption. When I looked at that engine it appeared to be very well designed and I like the coaxial reduction unit. However, it is an all-electric engine, kind of a oxymoron for a turbine as all they usually need to keep running is a fuel supply - no ignition required. Also, I would think that you would want to be able to flat-rate the engine as the power will go down with altitude - that would give the Allison an advantage as it has more horsepower available. Do you have an idea of the fuel burn for either turbine powerplant?

I will be following your progress with interest because that is what I had always wanted to do.

If you have to increase fuel capacity, then you compromise the planes performance. What is the fuel consumption for the turbines of your choice? The diesel may be the better alternative. jerb At 12:04 AM 1/2/04 -0500, you wrote: >--> Engines-List message posted by: Doug Ritter > >Knowing how critical the participants of this list are I anticipate a >certain degree of criticism for my ideas so here goes I am dead-set on an >alternative engine for my RV8A project that does not include an "old >fashioned" gasoline piston engine.

It seems that the fuel burn is in the mid 20's GPH. I am building a plane with 120gal capacity and still think that I can't carry enough for turbine use.

They have done a lot of fuel/altitude calc's and show that the total range is not that significantly affected for a long trip at high altitudes. They are using a helicopter jet engine converted for pure thrust. Joe N64CB I have seen this topic come up quite a bit.

Yep, that Greg is always out there on the Edge : ) Can't wait to see what it does. Tracy Crook
