PROBELESS AIRSPEED AND ANGLE OF ATTACK MEASUREMENTS FOR PROPELLER DRIVEN VEHICLES

Abstract:

An exemplary method to determine an airspeed and an angle of attack of a propeller powered vehicle includes determining the power delivered to the propeller, the air density, a propeller power coefficient, an advance ratio for the propeller, and the airspeed using the advance ratio and determining the angle of attack using the airspeed.
