US Patent 11383823 Single-axis gimbal mounted propulsion systems for aircraft

An aircraft has an airframe with a distributed thrust array attached thereto that includes a plurality of propulsion assemblies each of which is independently controlled by a flight control system. Each propulsion assembly includes a housing with a single axis gimbal coupled thereto and operable to tilt about a single axis. A propulsion system is coupled to and operable to tilt with the gimbal. The propulsion system includes an electric motor having an output drive and a rotor assembly having a plurality of rotor blades that rotate in a rotational plane to generate thrust having a thrust vector with a direction. Actuation of each gimbal is operable to tilt the respective propulsion system including the electric motor and the rotor assembly relative to the airframe to change the rotational plane of the respective rotor assembly relative to the airframe, thereby controlling the direction of the respective thrust vector.
