Hi italia458,
Thanks for the concise explanation.
NAVAVSCOLSCOM-SG-111 Page 4 at the top: (my bolding.)
"Thrust horsepower (THP) is propeller output, or the power that is converted to
usable thrust by the propeller."
We all agree.
A jet engine makes thrust a propeller engine makes power.
Please explain oggers' helicopter hover (when ias = zero) using your concept of the thrust horsepower of the blades (behaving like a big propeller).
