Vertical take-off and landing fixed-wing aircraft

Abstract

The invention relates to a vertical take-off and landing fixed-wing aircraft. The vertical take-off and landing fixed-wing aircraft comprises an aircraft body and semicircular wings, wherein the semicircular wings are symmetrically distributed relative to the aircraft body on the left and on the right; and propellers, which rotate around the axial directions of the semicircular wings, are arrangedin the semicircular wings. According to the vertical take-off and landing fixed-wing aircraft, as the semicircular wings are symmetrically arranged on the left and right sides of the aircraft body, the propellers, which rotate around the axial directions of the semicircular wings, are arranged in the semicircular wings, and the semicircular wings and the propellers integrally rotate around the axis perpendicular to the aircraft body, the vertical take-off and landing, hovering and cruising of an unmanned aerial vehicle are realized by adjusting postures of the semicircular wings and the propellers, the duration of flight of the unmanned aerial vehicle is prolonged, the volume and weight of the unmanned aerial vehicle are reduced by using the semicircular wings to replace the traditional fixed wings, the loading capacity and 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.

Description

technical field [0001] The invention relates to the field of aircraft, in particular to a vertical take-off and landing fixed-wing aircraft. Background technique [0002] With the rapid development of UAVs in various fields, the existing UAV models mainly include helicopters and fixed-wing aircraft. Among them, the helicopter can take off and land vertically and has strong maneuverability, but its endurance is weak and the load is small; the fixed-wing aircraft has strong endurance, but it needs a specific runway to take off and land, and has special requirements for the takeoff and landing environment. [0003] In addition, the prior art also records multi-rotor UAVs. Multi-rotor UAVs usually install multiple rotors on the fixed-wing fuselage, and use the rotors to achieve vertical take-off and landing. The operation is flexible and maneuverable, but the battery life is short. , weak load capacity. Contents of the invention [0004] In order to solve the above technical...
