Abstract

See full text

An aircraft includes a fuselage and a wing system having first and second oppositely disposed wings that extend laterally from the fuselage. A tiltable propulsion system is rotatably coupled to the fuselage between the first and second wings. The tiltable propulsion system includes a frame system having four diagonally extending arms each having a propulsion assembly coupled thereto. A flight control system is configured to independently control each of the propulsion assemblies and the orientation of the tiltable propulsion system. In a VTOL flight mode of the aircraft, the tiltable propulsion system is substantially perpendicular to the aircraft's yaw axis in a vertical thrust orientation such that the propulsion assemblies are configured to provide vertical thrust. In a forward cruise flight mode of the aircraft, the tiltable propulsion system is substantially perpendicular to the aircraft's roll axis in a forward thrust orientation such that the propulsion assemblies provide forward thrust.
