1) You are sooo correct Vance, according to everthing I have always been taught.1) In my opinion the airflow directed downward by the driven region in the vertical descent is what slows the descent.
2) Significant how?
3) In my opinion the horsepower consumed by the rotor goes down as the indicated airspeed increases.
3) That is true up to the ideal autorotation speed (best L/D). Above that speed induced drag goes up significantly and to keep RPM up, the rotor uses
more HP. The "HorsepoweSeconds Needed Curve looks like an upside down "U" if airspeed is the x axis and power required is the y axis.
