Thanks for the input. I see. So seems the microturbine used in
generators have inherent problems to be converted to use on aircraft.
Thank you.

the thing that kills these as an idea is the fuel consumption.
a continental O-200 burns about 20 litres per hour.
a jabiru 2200 burns about 13 litres per hour.

the small fadec turbine that aeromodellers use burns about 60 litres
per hour for just 15lbs thrust.

afaik the KR2 powered by a turbine was built wet everywhere (fuel
tanks placed everywhere) and had an endurance of just 18 minutes.

not a practical idea without some serious reengineering.

I guess my math is wrong they spec 350ml per minute for the 30lb thrust
unit
which works out to 21 litres and hour. Sounds a bit fishy but who knows.
5.5 gal/hour for 30lbs thrust, maybe!

If that works out to 1.1 lb/lbf/hr sfc that does sound a bit fishy. Kinda
low for one of these little screamers, IMO. I talked to Bob Carlton a couple
of weeks ago, he does the Silent Wings air show act with the two AMT engines
on the Silent motorglider. _Very_ cool stuff. He's got two 45 lbf AMT-USA's
and he's burning 20 gals/hr total (both engines) at 100% N1.

Does he have a website with the plane on it?
