Abstract: A method for providing peak efficiency propeller control includes determining an optimal propeller blade angle via a control system having settings and readings including advance ratio, propeller RPM, and electric motor torque. If any limits, such as maximum propeller RPM, allowable blade angle, or motor torque are violated, then a non-optimal blade angle may be found which does not violate any of the limits. The controller connects to sensors to measure the speed and altitude of an aircraft, and using advance ratio, is able to determine thrust and power contours for a blade-angle domain such that the optimum blade angle is determined in real-time for a wide range of flight conditions.
