Theres some good information in a lot of his posts that I'm going to post
here. Some of it not relevant, but most of it is very interesting. I had
emailed him asking for permission but never got a response. Since it's on a
public Yahoo serverm it available there anyway.
First, it appears that a large number of NACA papers are not in the
collection.

If someone has good bandwidth, and access to the local mirror, can you
verify if these reports are currently included in the local mirror.
Advice DW ( Internet Personality ) with the results and how to blend
them. Thanks.

A cross between a turbo-piston engine and a "jet" engine that at speeds
above 400 klicks is superior to a piston engine.
Basically, a radial engine drives a forward mounted centrifugal
compressor, with some air bleed for supercharging, and the rest blown
over the engine. This air mass is then injected with exhaust and
becomes an exhaust aided injector.
The waste energy from the engine is combined with the air stream, and
this energy is added to the air and ejected in a controllable exhaust
jet. This would be correctly called as adding heat, but, since there
are about 3 people that understand thermodynamic heat is not identical
to temperature, I will use the generic energy addition statement.
