Electric coaxial multi-rotor helicopter based on contra-rotating double-rotor motor

Abstract

The invention discloses an electric coaxial multi-rotor helicopter based on a contra-rotating double-rotor motor, which comprises a helicopter body; a main rotor wing system which is located in the center of the upper portion of the fuselage and comprises an upper rotor wing and a lower rotor wing which are coaxial, and a contra-rotating double-rotor motor which is arranged between the upper rotorwing and the lower rotor wing and used for enabling the upper rotor wing and the lower rotor wing to achieve coaxial reverse constant-speed rotation; the main rotor system is used for providing mainflight power for the helicopter; an auxiliary rotor wing system which is located below the main rotor wing system, the auxiliary rotor wing system comprises four control rotor wings, and the four control rotor wings are evenly distributed at the four corners, away from the gravity center of the fuselage by a certain distance, of the fuselage; and the auxiliary rotor system provides attitude control for the helicopter. The electric coaxial multi-rotor helicopter has the advantages of simple structure, strong cruising ability, low power consumption, low manufacturing and using cost and the like.

Description

technical field [0001] The invention relates to the technical field of aircraft design and manufacture, in particular to an electric coaxial multi-rotor helicopter based on counter-rotating double-rotor motors. Background technique [0002] Existing electric helicopters generally directly replace the engine as a power source with an electric motor, and its control mode has not changed, so there are still defects such as complex structure, high energy consumption, and poor endurance. At the same time, a multi-rotor can also be regarded as a multi-rotor helicopter, but the rotors of the multi-rotor will interfere with each other, resulting in more rotors and lower efficiency. [0003] Therefore, how to overcome the above-mentioned technical defects of the existing electric multi-rotor helicopters is a direction that those skilled in the art need to study. Contents of the invention [0004] The present invention aims to solve one of the above-mentioned technical problems in ...
