propeller RPM x torque x k = shaft hp
Torque is measured in PSI in these kiwi kites. For the PT6A-34AG in this formula k=0.00581
yr right, there does not seem to be a variable in this formula to account for bypass being open or not, which leads to the conclusion that if you can still get the same torque bypass open or closed, the engine is producing the same power and performance will be... the same.
Aerodynamic drag? Maybe. Still going underneath the radar for me
