Dual-flight mode tandem rotor wing

摘要

A vertical takeoff and landing aircraft (10) is provided including an aircraft fuselage (12). A plurality of hubs (20) are mechanically coupled to the fuselage (12) and are rotated by at least one engine (22). A plurality of tandem rotor/wings (14) are mechanically coupled to the plurality of hubs (20) and propel and lift the aircraft fuselage (12). A transitional lift wing (16) is mechanically coupled to the fuselage (12) and enables lift on the fuselage (12) during off-loading lift of the plurality of tandem rotor/wings (14). A main controller (24) is coupled to the plurality of tandem rotor/wings (14) and switches the plurality of tandem rotor/wings (14) between a vertical lift mode and a fixed wing mode. A method of performing the same is also provided.
