How do you know the text is credible?
Because you told me it was "Fundamentals of Aerodynamics" produced by the US Naval Aviation Schools Command. That and the fact that drag x airspeed = power required is hardly controversial.
But you are waffling again. The bottom line is you believe:
You could be creating 200 BHP, at a steady RPM, while stopped on the ground and your thrust horsepower would be zero.
This is incorrect. If you are creating 200 BHP it's because you are moving a mass of air over a distance, and at a rate equivalent to 200 BHP x [efficiency of prop and transmission].
BTW I see Keith Williams has now posted exactly the same thing as morrissman. Would you make the same statement now to Keith as you did to morrissman? ie
What you're talking about is engine inertia which only produces a turning moment (torque) when the engine is accelerating (positive or negative).
