Regarding Helos running full throttle -
A gas turbine engine runs like a constant speed prop
recip engine set up.
Run up the engine to performance RPM. You do the same
in a Cessna 182 or other constant speed prop.
Then increases the pitch of the blades. More fuel is
added, the governor holds the rpms at the same speed, but
more power comes out the shaft.
A chopper goes up, a plane goes forward.
What is seen in a gas turbine is that the compression blades operate at their own rpm, which is different from a recip. The later set of blades which captures the power is the one that stays constant.
So saying they run at full throttle is mis-leading as the compression stage changes rpm to maintain constant rpm on the output, thus power.
did that help?
Constant speed prop I know - learned on a ‘49 Ryan Navion in late 50’s! Then Commanche 180, then Twin Commanche, then Cessna 337.
Only makes sense.
Actually my Ford tractor is the same using the hand throttle: set RPM, regardless of work load, engine RPM is maintained by constant speed throttle. Foot throttle on the other hand operates like a car.
I’ve known several chopper pilots, and understand how the collective works and the stick, but missed the throttle part......my bro has flown a chopper too......
THANKS!
