<<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. A small gas turbine is my number one
choice, a piston diesel is second and a rotary is third. Two choices for
the turbine are an Allison 250 series T63 (250 to 300 hp) and the newly
under development ATP (Affordable Turbine Power 200+ hp) I have done a lot
of product research and selected several vendors for the Allison at around
$13k for a basic engine. My request is to make contact with any of you who
have a similar desire and/or experience. I'm not trying to push the RV to
the limits of the envelope just I just love turbines and want to be a
little different. Thanks

I would think the Allison would be an excellent choice in view of its
operating history in helicopters (that is the engine in the Jetranger?).
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 wanted to wish you well (and cheer you on) in your search for a
turbine. I will be following your progress with interest because that
is what I had always wanted to do.
Please keep us posted,

What would your range be - turbines like fuel even at idle - it could
severely limit the airplanes usefulness. 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.

I have seen this topic come up quite a bit. 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.

The EZ Hanger is building a jet powered cozy. 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.

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