Abstract

The invention discloses a coaxial propeller UAV (Unmanned Aerial Vehicle). The coaxial propeller UAV comprises a rack, propellers, motors, supporting legs, a flight controller and connecting shafts, wherein the rack is at least provided with four shafts; the motors are arranged above the tail ends of the shafts; the supporting legs are arranged under the tail ends of the shafts; the supporting lesare used for supporting the rack; the rack is provided with the flight controller; the rack is also provided with lithium batteries for supplying power to electric components; the flight controller is used for controlling a multi-rotor UAV; two propellers are arranged above each motor, the two propellers are vertically distributed on one corresponding connecting shaft, a first propeller is arranged at the top part of the connecting shaft, and a second propeller is arranged at the middle part of the connecting shaft; the tail ends of the connecting shafts are connected with the motor. According to the coaxial propeller UAV disclosed by the invention, the maneuverability is good, and the lift force of two pairs of coaxial propellers is greater than that of a single propeller under the situation that the same motor is used.

Description

technical field [0001] A coaxial propeller unmanned aerial vehicle belongs to the technical field of unmanned aerial vehicles, and in particular relates to a multi-rotor unmanned aerial vehicle in which two propellers are arranged on the same motor. Background technique [0002] A drone is an unmanned aerial vehicle operated by a radio remote control device or its own program control device. It first appeared in the 1920s, when it was used as a target drone for training. is a term used by many countries to describe the latest generation of unmanned aircraft. Literally, the term can describe cruise missiles that have evolved from kites, radio-controlled aircraft, and V-1 missiles, but in military terms it is limited to reusable heavier-than-air vehicles. UAVs have a wide range of uses, low cost, good cost-effectiveness ratio; no risk of casualties; strong survivability, good maneuverability, and easy to use. They play an extremely important role in modern warfare and have b...
