Publication number: 20250074586Abstract: A restructurable hybrid-wing VTOL aircraft includes a fuselage, two wings, two canard wings and a cabin door. The two wings are provided to opposite sides of the fuselage. Each the wing is provided vertically and symmetrically by two rotary wing modules, and thus an H configuration to the fuselage can be formed. While the lower rotary wing module rotates to align the corresponding wing, a change of relative position with respect to the upper rotary wing module can be generated. Through the rotation of the lower rotary wing module, the vertical surface thereof would be transformed into a lift surface for enlarging the aspect ratio of the wing to improve the corresponding lift-drag ratio. Thereupon, a disadvantage of hyper flight-directional stability to the H-configured tail seat-type aircraft caused by the vertical area of the aircraft can be reduced, and so the tail-seat type aircraft can slide to emergency land.Type: ApplicationFiled: October 25, 2022Publication date: March 6, 2025Inventors: YU-LIN ZHANG, LI FAN, JUN-HUA XIANG, YUN-HAN HE, GUANG-WEI WEN, WEI QIU
