Title:
UNMANNED AERIAL VEHICLE
Document Type and Number:
WIPO Patent Application WO/2019/104796
Kind Code:
A1
Abstract:
An unmanned aerial vehicle, comprising: a fuselage (1), a connecting mechanism (2) and at least one wing (3), wherein the wing (3) is rotatingly mounted on the fuselage (1) by means of the connecting mechanism (2); and during the flight process of the unmanned aerial vehicle, the wing (3) automatically adjusts the angle of attack under the action of incoming air. In the unmanned aerial vehicle, at least one wing (3) is rotatably connected to the fuselage (1), and the wing (3) may automatically adjust the angle of attack under the action of incoming air, so as to continuously produce stable lifting force during the flight process of the unmanned aerial vehicle, which greatly improves the lifting effect of the wing. The overall structure of the unmanned aerial vehicle is simple and convenient to mount, the energy consumption is reduced, and the flight efficiency of the unmanned aerial vehicle is improved.
