Operating multirotor aircraft with enhanced yaw control

Abstract:

This disclosure describes a configuration of a multirotor aircraft that will facilitate enhanced yaw control. The multirotor aircraft includes one or more adjustable members that will twist the frame of the multirotor aircraft, thereby adjusting the orientation of the motors and propellers and enhance the yaw control of the multirotor aircraft. In some implementations, the adjustable member(s) are passive and twist in response to differential thrusts generated by the propellers. In other implementations, the adjustable members are active and twist in response to a yaw command from the multirotor aircraft control system.
