Yea, I used to have get out and spin the props on a B-100 king air once in a while. I didn't realize that there was a nozzle coking issue involved, thanks.belchfire said:FN, tormenting the fng's again! hehehe!
Kind of makes you respect the simpler and less efficient PT-6.Diesel said:Simcom has a cutaway garett that you can spin and see how everything works.
Alll i can say is holy crap look at all those gears.
MauleSkinner said:You do this basically in one of two ways...spin the prop to blow out residual heat, so that the temperature differential isn't so great,
or turn the prop enough to flip the engine 180 degrees, so that the hot (expanded) part is now on the bottom cooling and shrinking, and the cool (not expanded) part is now on top, heating and expanding, resulting in "un-bowing" the engine.

Question 1: Just spin it til you're tiredFL420 said:Since the engine is geared, do you happen to know how many "blades" you should turn to ensure you have released the residual heat?
Related question. How many "blades" to turn the shaft 180 degrees?

that if you reduced combustion chamber temp
by spinning the props within a minute or so of
shutdown you could significantly reduce the
buildups on the nozzels.
