A multi-rotor upright vehicle

Abstract

The invention relates to the technical field of aircraft, in particular to a multi-rotor upright aircraft. Comprises a frame, a driving device, a transmission mechanism, a rotor bracket, a plurality of rotors, a tail wing, a synchronizer, a protection device, a direction control device and a controller, wherein the rotor bracket is arranged on the frame, the plurality of rotors are arranged on therotor bracket, and the tail wing is connected with the frame; The driving device, the controller and the synchronizer are all arranged in the frame, the synchronizer is connected with the driving device, and the synchronizer is connected with a plurality of rotors through the driving mechanism; Adopt engine instead of electric motor to drive rotor, improve all-weather long-distance service ability; The synchronizer technology is used to drive the multi-rotor to rotate, so that the symmetrical rotor has the same rotational speed and input power, which ensures the symmetrical lift force. The automatic longitudinal and lateral trimming technology of aircraft uses a tail motor to achieve tilting and rotational speed changes, and to carry out longitudinal and lateral trimming of aircraft, thusachieving stable flight.

Description

technical field [0001] The invention relates to the technical field of aircraft, in particular to a multi-rotor helicopter aircraft. Background technique [0002] Most of the existing multi-rotor aircraft are driven by electric motors, which results in short flight time and light load. Some multi-rotor aircraft are driven by engines, but these multi-rotor aircraft are complex in structure, and they all adopt the pitch control method. The control and execution are integrated. In one body, the control is complicated, the failure rate is high, the reliability is poor, and the maintenance cost is high in the later period; secondly, there is no safety protection device on the multi-rotor aircraft. Once the aircraft loses control and falls, it will not only cause losses but also cause harm; When flying, it is inconvenient to control the direction, and it is not stable enough when turning the direction, and there is a hidden danger of easy loss of control.

Some multi-rotor aircraft are driven by engines, but these multi-rotor aircraft are complex in structure, and they all adopt the pitch control method. In one body, the control is complicated, the failure rate is high, the reliability is poor, and the maintenance cost is high in the later stage; secondly, there is no safety protection device on the multi-rotor aircraft. Once the aircraft loses control and falls, it will not only cause losses but also cause harm; When flying, it is inconvenient to control the direction, and it is not stable enough when turning the direction, and there is a hidden danger of easy loss of control
