Patent number: 11242142Abstract: An aircraft has a fuselage, and pivot wings pivotally connected with the fuselage, the pivot wings pivoting between a vertical orientation for vertical takeoff, and a horizontal orientation for horizontal flight. Ailerons on each of the pivot wings provide roll control for the aircraft in all phases of flight. A gimbal motor assembly is mounted on the fuselage to adjustably support a motor. An upper rotary pivot free wing is mounted on a mast driven by the motor. A vectored thrust mechanism is provided for forward movement of the aircraft.Type: GrantFiled: March 12, 2019Date of Patent: February 8, 2022Inventor: Stanley Gordon Sanders, II
