Columnar and coaxial double-propeller miniature unmanned aerial vehicle

Abstract

The invention discloses a columnar and coaxial double-propeller miniature unmanned aerial vehicle, comprising a load-carrying structure, wherein the load-carrying structure comprises a columnar vehicle body, a flight controller and a battery are arranged in the columnar vehicle body, a mission payload is arranged at one end of the columnar vehicle body, a coaxial reversing motor is mounted at the other end of the columnar vehicle body through an omni-directional suspension bracket, a double-propeller rotor wing head is mounted on the coaxial reversing motor, a rotor wing of the double-propeller rotor wing head can be folded to cling to the columnar vehicle body, and the double-propeller rotor wing head, the coaxial reversing motor and the columnar vehicle body are arranged coaxially. According to the columnar and coaxial double-propeller miniature unmanned aerial vehicle, as a rotor wing surface of the double-propeller rotor wing head can be inclined through the omni-directional suspension bracket, so that the attitude of the unmanned aerial vehicle is controlled; as the double-propeller rotor wing head can be folded to cling to the vehicle body, the unmanned aerial vehicle has a higher portability and usability; and the double-propeller rotor wing head can be stored in a launching tube after being folded, and therefore is easy to deploy and release.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a micro unmanned aerial vehicle with columnar coaxial double propeller layout. Background technique [0002] Rotor UAV is a kind of multi-purpose vertical take-off and landing aircraft. Compared with fixed-wing UAVs, rotary-wing UAVs can take off and land vertically, have low requirements for take-off and landing sites, and are convenient and efficient to use. Rotor UAVs are widely used and can perform tasks such as aerial photography, medical rescue, weather detection, and aerial inspection. [0003] The traditional helicopter layout is configured with a main rotor and a tail rotor. The transversely arranged tail rotor is used to counteract reactive torque and to control yaw. The traditional helicopter layout uses a set of very complicated swash plate and linkage mechanism to control the tilt of the rotor surface, and uses the free-wind or semi-free-wind roto...
