Power device, aircraft and aircraft control method

Abstract

The invention provides a power device with multiple tilting degrees of freedom, an aircraft whose power device can be tilted with multiple degrees of freedom, and an aircraft control method that makes the aircraft easy to control. The power device provided by the present invention includes a ducted power unit, a mounting arm, a connecting arm and a support frame, the support frame is supported on the outside of the ducted power unit, and a first steering gear is arranged on it, and the first steering gear makes the duct power The unit rotates around a first rotation axis perpendicular to the rotation axis of the ducted power unit; the connecting arm is connected to the support frame, and the connection arm is provided with a second steering gear, and the second steering gear makes the support frame rotate around a shaft perpendicular to the first rotation axis. The second rotating shaft rotates; the connecting arm is connected with the mounting arm, and a third steering gear is arranged on the mounting arm, and the third steering gear makes the connecting arm rotate around a third rotating shaft perpendicular to the second rotating shaft. The ducted power unit can be tilted in all directions, thereby quickly realizing the advantages of steering in all directions of the aircraft. The control of the power unit is more flexible and the maneuverability is good.

Description

technical field [0001] The invention relates to the field of aircraft, in particular to a power device for the aircraft, an aircraft with the power device and a flight control method for the aircraft. Background technique [0002] A ducted power unit is a device that provides power for an aircraft, and generally includes a ducted tube, a rotor located in the ducted tube, and a driving motor thereof. Multi-rotor aircraft generally have multiple ducted power units to provide flight power for it. [0003] Most of the existing multi-rotor aircraft are controlled by the counter torque of the rotor when turning, because the rotor generates counter torque to the rotating shaft when it rotates. Usually, there are even number of rotors, and the reaction torque generated by half of the rotors makes the multi-rotor aircraft rotate in a clockwise direction, and the reaction torque generated by the other half of the rotors makes the multi-rotor aircraft rotate in a counterclockwise dire...

AI Technical Summary

Problems solved by technology

However, the existing multi-rotor aircraft generally only have one tilting degree of freedom, and the flexibility and maneuverability of the aircraft are still insufficient.

Moreover, when the aircraft encounters severe weather such as strong winds, the fuselage may be blown into a rollover posture, making the flight of the aircraft even more difficult to control
