Title:
VERTICAL TAKEOFF AND LANDING FIXED-WING AIRCRAFT
Document Type and Number:
WIPO Patent Application WO/2019/090999
Kind Code:
A1
Abstract:
A vertical takeoff and landing fixed-wing aircraft comprises a fuselage and semicircular wings (2) symmetrically distributed relative to the fuselage on the left and on the right. Propellers (3) rotating around the axial directions of the semicircular wings are disposed in the semicircular wings. The semicircular wings are symmetrically disposed on the left side and the right side of the fuselage, the propellers rotating around the axial directions of the semicircular wings are disposed in the semicircular wings, and the semicircular wings and the propellers integrally rotate around the axis perpendicular to the fuselage; an unmanned aerial vehicle vertically takes off and lands, hovers and cruises by adjusting the attitudes of the semicircular wings and the propellers, thereby reducing the duration of flight of the unmanned aerial vehicle; by replacing traditional fixed wings with the semicircular wings, the volume and the weight of the unmanned aerial vehicle are reduced, the loading capacity and the flexibility of the unmanned aerial vehicle are improved, the operation of the unmanned aerial vehicle is stable, and the aerodynamic performance of the unmanned aerial vehicle is good.
