I do not really know anything about the Turbine 8E project  but  very little
of the information in the article passes the "sanity test".    To my
knowledge, Ross does not make a drive with a ratio higher than 3.17 - 1.  I
will also go out on a limb and say that none of them would survive longer
than a few minutes at 66,000 rpm.   Even with clipped wings, the old
Luscombe would take a lot more than 150 HP to get to 172 mph at sea level.
(maybe they meant at 20,000 ft?)    No offence, but  when you consider the
very burdensome FAA requirements when operating a certified aircraft in the
experimental category, the whole thing sounds like a bad joke.  Or an
ingenious publicity stunt.

What about the heat factor, Tracy ????,  Jeff???,  Paul???

After getting past the BS factor, then worry about the heat factor.  Sorry,
that wasn't nice.  Did you mean heat factor of the turbine or the rotary?
Cooling the rotary is not the insurmountable problem that you might imagine.
Just takes attention to the basics of thermo and aero-dynamics.  Been a lot
of good discussion here on that subject.
