Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicles, in particular to a multi-rotor unmanned aerial vehicle with a coaxial double propeller structure. Background technique [0002] Unmanned aircraft, referred to as "UAV", is an unmanned aircraft controlled by radio remote control equipment and its own program control device. There is no cockpit on board, but it is equipped with autopilot, program control device, information collection device and other equipment. The personnel on the ground, on the ship, or at the remote control station of the parent aircraft track, locate, remotely control, telemeter and digitally transmit it through radar and other equipment. Under the radio control, it can take off like an ordinary aircraft or be launched into the air with a booster rocket, and it can also be taken into the air by the parent aircraft for flight. [0003] The UAV in the prior art includes a fuselage and a rotor shaft, one end of...
