Feathering the propeller

The purpose of varying pitch angle is to maintain an optimal angle of attack for the propeller blades, giving maximum efficiency throughout the flight regime. This reduces fuel usage. Only by maximising propeller efficiency at high speeds can the highest possible speed be achieved. Effective angle of attack decreases as airspeed increases, so a coarser pitch is required at high airspeeds. WebReverse – Feathering vs Fixed: One of the most important benefits of a feathering prop is the reverse performance. The blades rotate 180 degrees in ¾ turn of the shaft, so we get the same efficiency in reverse as in forward with the Max-Prop, (about 80% better than a fixed propeller according to the mfr).
