Got Hay to make today so I don't have time to respond to everything now. And may be burnt tonight.

But here ( from memory and it's been 20 + years ) are the numbers on a P-3 engine

The turbine makes 10,000 hp
6000 are used to turn the compressor on the ground
40 in the gear box
so 4600 hp gets into the prop in flight
And there's 500 lb. of thrust at full power.
JFOI

And the lag time is so short power is there Right Now! Not so with a pure jet. You have a life time of delay. ( same with a turbo charged recip. if you let RPM's fall) And this has made more than one jet buy the farm.

500lbs thrust? That can't be Sl static? I believe a 0-360 with a fixed pitch prop puts about that out at 140 mph.

5000lbs thrust would be about right.

Pukin dog, would you deploy spoilers and keep the engines spooled up on a 777 if you were to be low and slow? Seems like that would take care of the spool up argument.

Also, isn't flight idle on most HB turbofans about 20% thrust?

Does 16K thp sound about right for sl static? That would assume %85 prop eff.
