Title
(EN) Aerial vehicle including autonomous rotor speed control
Abstract
(EN)

A rotary aerial vehicle (AV) includes an engine configured to rotate at least one rotor at a variable rotor speed, a full authority electronic microcontroller (FAEM) in electrical communication with the engine. The FAEM is configured to output at least one electronic engine control signal that controls operation of the engine. An electronic rotor speed microcontroller (ERSM) is in electrical communication with the FAEM, and the ERSM is configured to dynamically determine at least one mission objective of the rotary AV, and outputs an electronic rotor speed control signal that commands the FAEM to adjust the rotor speed of the at least one rotor.
