Patent number: 11485488Abstract: A vertical take-off and landing aircraft includes a fixed wing airframe having opposed first and second wings extending from first and second sides, respectively, of a fuselage having opposed leading and trailing extremities, and a tail assembly located behind the trailing extremity. Vertical take-off and landing (VTOL) thrust rotors are mounted to the airframe providing vertical lift to the aircraft, and a forward thrust rotor is mounted to the airframe for providing forward thrust to the aircraft. At least one of VTOL thrust rotors is laterally tilted with respect to the airframe for providing vertical lift and yaw control authority to the aircraft.Type: GrantFiled: December 4, 2015Date of Patent: November 1, 2022Assignee: L3HARRIS LATITUDE LLCInventors: Justin Armer, Carlos Murphy, Jason Michael K.
