Abstract
A plurality of port-side tilt rotors and a plurality of starboard-side tilt rotors are configured to rotate between a first rotor position and a second rotor position. The port-side tilt rotors are coupled to a trailing edge of the fixed and forward-swept wing on the port side and the starboard-side tilt rotors are coupled to the trailing edge of the fixed and forward-swept wing on the starboard side. The aircraft also includes a fuselage. When the port-side and starboard-side tilt rotors are in the first rotor position, at least some of a lift to keep the aircraft airborne comes from thrust output by the rotors at least some of the time. When in the second rotor position, at least some of the lift to keep the aircraft airborne comes from aerodynamic lift on the fixed and forward-swept wing at least some of the time.
