Problems solved by technology

However, since the rotor of the rotorcraft is stationary relative to the central axis of the rotor, the forward resistance is relatively large, so the energy consumption is large, the aerodynamic efficiency is low, and it is difficult to fly with high power and long endurance

Abstract

The present invention discloses a two -horizontal two -rotating four -wheel wing drone. It is characterized by the wheel wing, drive mechanism, cam, rotating shaft, reducer, motor and fuselage framework.The symmetrical layout on both sides of the fuselage frame has two vertical rotating shafts. The symmetrical layout of the front and back of the fuselage frame has two levels of rotating shafts. The installation of the fuselage frame is fixed with four cams. It is set on the fuselage framework.The four electric motors on the top of the fuselage are set up by the four reducers on the fuselage frame. The four rotating shafts are continuously rotated.The wing is used to generate thrust, and the two wheel wings are used to generate lift. The four transmission mechanisms connect four wheel wings and four cams respectively.The rotating blades, cam and transmission mechanisms are used to control the rotation and reset of the blades.

Description

technical field [0001] The invention relates to the field of movable-wing aircraft and flying robots, in particular to a two-horizontal, two-vertical blade rotatable four-wheeled movable-wing unmanned aerial vehicle. Background technique [0002] There are three flight types of aircraft: fixed wing, rotary wing and flapping wing, both of which are movable wings. [0003] Flapping wing flight is a flying method adopted by flying creatures in nature. It mainly uses the up and down flapping of the wings to generate lift and thrust at the same time. Flexibility, more suitable for performing flights around obstacles etc. For small-sized and low-speed aircraft flying under low Reynolds numbers, the unsteady lift generated by the flapping wing is much greater than the constant lift of the fixed wing; from the perspective of thrust, the propulsion efficiency of the flapping wing is higher than that of the propeller. At present, the research of flapping-wing aircraft mainly focuses...
