TAILSITTING BIPLANE AIRCRAFT HAVING A COAXIAL ROTOR SYSTEM
An aircraft (10) operable to transition between thrust-borne lift in a VTOL orientation and wing-borne lift in a biplane orientation. The aircraft (10) has an airframe including first and second wings (14, 16) with a fuselage (18) extending therebetween. A propulsion assembly (22) is coupled to the...

| description | An aircraft (10) operable to transition between thrust-borne lift in a VTOL orientation and wing-borne lift in a biplane orientation. The aircraft (10) has an airframe including first and second wings (14, 16) with a fuselage (18) extending therebetween. A propulsion assembly (22) is coupled to the fuselage (18) and includes a counter-rotating coaxial rotor system (24) that is tiltable relative to the fuselage (18) to generate a thrust vector. A flight control system (20) is configured to direct the thrust vector. In the VTOL orientation, the first wing (14) is forward of the fuselage (18), the second wing (16) is aft of the fuselage (18) and the coaxial rotor system (24) is configured to provide thrust in line with a yaw axis of the aircraft (10). In the biplane orientation, the first wing (14) is below the fuselage (18), the second wing (16) is above the fuselage (18) and the coaxial rotor system (24) is configured to provide thrust in line with a roll axis (10a) of the aircraft (10). |
