Problems solved by technology

[0003] However, as people have higher and higher functional requirements for the aircraft, there are still many problems in the existing aircraft. The single-blade aircraft has limited lift and poor stability, while the coaxial dual-blade aircraft has slow moving speed and slow attitude change. The combination of the two, switching during the flight involves the problem of difficult control of stability, and it is difficult to meet the multi-functional needs of users

Abstract

The invention discloses a multi-rotor aircraft using planetary gear to switch between a single-propeller and a coaxial twin-propeller, which comprises a frame, a control unit, a planetary gear, an electric motor, a main rotor and an aileron. The frame comprises a first circular frame of a top layer and a second circular frame of a bottom layer connected to each other. The control unit is connectedwith the rack. The planetary gear is arranged in a second circular frame, and the first circular frame is connected with a motor and a main rotor through a plurality of first support rods. The secondcircular frame is connected with an electric motor and an aileron through a second support bar and a third support bar; the number of main rotor and aileron is the same, and the number is even. By using the advantages of planetary gears, stable motion, strong shock resistance and vibration resistance, the single-rotor and coaxial double-rotor modes can be switched smoothly in the air. The advantages of the two modes are large lift, strong stability and flexible attitude change, and both of them have advantages.

Description

technical field [0001] The present invention relates to the field of aircraft technology, and more specifically relates to a multi-rotor aircraft that utilizes planetary gears to switch single propellers and coaxial dual propellers. Background technique [0002] At present, with the continuous development of science and technology, there are more and more types of rotorcraft. The existing aircraft on the market are generally single-blade aircraft or coaxial dual-blade aircraft, which can be controlled by wireless remote control. The single-blade aircraft is easy to control and mobile. Fast speed, flexible attitude change, large lift force, strong stability, and fast climbing speed of the coaxial scull aircraft have their own advantages. [0003] However, as people have higher and higher functional requirements for the aircraft, there are still many problems in the existing aircraft. The single-blade aircraft has limited lift and poor stability, while the coaxial dual-blade a...
