Of course, high speed cruise is more to show off. Long range cruise would be more practical.



In the PT6 applications I've flown, high-speed cruise was the most economical once you took the (hours-based) engine reserves into account. Of course with $6 Jet-A that may be changing.

Curt:

Did you look at the fuel flow amounts Darwin provided? In light of that, and the cost of fuel, why would high speed cruise be more economical? Is it because of engine time replacements?
I don't have any time behind -21s. The turbine time I do have was courtesy of Uncle Sam.

Best,

Dave

I'll add one data point: Having your glider towed by a sprayer with a PT-6 is eye-opening <g>.

Yessir! Even with my heavy as #=!!, water laiden open class bird at Uvalde in August - moved up right smart I'd say.

The log book says that according to the recording GPS, the tow lasted 41 seconds from start of roll to release at 2130' AGL. It is the only tow I remember where the only reference I had to staying in position behind the tow plane was the wing-tips poking out on either side of my nose - I probably had a deck angle of 15 degrees or so, even with full flaps. No way I could see him over the nose. Flew the whole tow with one hand on the release, just in case.

OOPS! Make that 101 seconds, or 1:41 minutes (someday I'll learn to type, or at least proof-read my posts.)

Still mighty impressive from my perspective.

Here's the latest from Darwin at Rocket Engineering.

Best,

Dave

David, We are pleased to announce the first flight of the Turbine Cougar Baron.

The first flight was September 16,2008 and since then it has flown 4 more times.

The performance is better than expected and the flight and handling qualities are

very docile, much, much better than the original. Takeoff is awesome, power up to

500# torque, release brakes and in 6 seconds the aircraft is passing through 80 kias

with smooth rotation up to 140 kias and at full power (500 hp/side) the climb rate is

between 4000 to 5000 fpm. We have only been to 13,500 so far and 200 kias is

achieved on only 24 gallons per side.



We will have more data to send you in the next few weeks but I though you would

appreciate this info. I have flight tested for the FAA many aircraft and this is by far

the highest performance aircraft I have ever flown, the Ferrari of aircraft.

"only" 24 gph per side????

To my knowledge they can't put tip tanks on that wing.

Dave,

Next time you speak/write to Darwin, please say "hello" to him for me.

Scott,

>>>I thought there weren't any rich people left after this week?! <<<

I talked to someone today that said Lehman had a G450 for sale..

They have a delivery for next month on a new G550..

I wonder who will buy that position, from what I hear that's no problem.

Jeff

nothing clever to say right now...
