Abstract

The invention relates to a control technology of a rotor unmanned aerial vehicle, belonging to the technical field of aircraft design. A kind of double-rotor unmanned aerial vehicle, comprises upper rotor, lower rotor and equipment cabin, is provided with yaw angle adjustment device between upper rotor, lower rotor and equipment cabin; Said yaw angle adjustment device includes power unit, transmission device And connectors, power device and transmission device are two groups; the power device is used to provide power support for the rotation of the upper rotor and the lower rotor, one end of which is connected and fixed with the equipment cabin through the connecting device, and the other end is connected with the transmission device; the transmission device The other ends of the shafts are respectively connected to the ends of shaft I and shaft II; the connectors are arranged between shaft I, shaft II and the transmission device to realize the rotational connection between the upper rotor, the lower rotor and the power unit; the upper rotor, the lower rotor The direction of rotation is opposite. Beneficial effects of the invention: 1. Double rotors are adopted, and the structure is more compact. 2. Simplified structure and lighter weight. 3. Less affected by the external environment. 4 Strong practicability, easy popularization and application, and great value.

Description

technical field [0001] The invention relates to a control technology of a rotor unmanned aerial vehicle, belonging to the technical field of aircraft design. Background technique [0002] Aircraft generally use aerodynamic control, such as adjusting the rudder surface of a fixed-wing aircraft and adjusting the blades of a rotorcraft, all of which use aerodynamic force to change the attitude and flight direction of the aircraft. However, if the aircraft is controlled by aerodynamic force, it will be difficult to control the aircraft when encountering turbulence. In addition to the aerodynamic force, the aircraft is also affected by other loads such as inertial force. When the aircraft changes the center of gravity of the aircraft during flight, the attitude of the aircraft will also change. For example, on a small business jet, when passengers walk from the nose to the tail, the plane will pitch accordingly. Therefore, controlling the center of gravity of the plane can also ...
