Pauls has anyone tried this engine wiith tracys redrive? I've seen alot
of these in the Rotorway Turbo Exec. 160hp not bad. How thirsty is it
though? and can it be throttled up and down without a bunch of frequency
issues?

Tony

Not that I know of. BSFC could be as high as 1 or 160 pounds per hour or
26.6 gallons an hour for 160 HP.


Paul Lamar ...No rotor no motor.



There is a fellow here in Austin that has a 1 set helicopter with one of
these engines. I think he said it idles at 12 gph and 14 gph WOT.

He is dreaming :) That is a BSFC of .525 no way in hell will that happen
with a small turbine.

Derated to 90hp


Modified Solar T62 turbine 160 derated to 90 hp
Single Seat 220 lbs max
Gross Weight 850 lbs
Empty Weight 500 lbs
Fuel Capacity   (Note: Optional +5 only for 180lb & Less pilot weight)
21 (16 + 5 reserve) US gal
Range with reserve 160 miles

He is getting about 1:15 flight.

Bobby

If he is only using 90 HP he is burning less fuel.

BSFC is a measure of how much fuel is burned for each HP.

A piston engine would burn 40.5 pounds per hour or 6.75 GPH
at 90 HP.
