Description

A vector quadcopter with the ability to keep the body level

technical field

The invention relates to the field of aircraft design, in particular to a vector quadcopter capable of keeping the body level.

Background technique

In recent years, with the development of power electronics technology and the demand for increased productivity, quadrotor unmanned aerial vehicles have been the focus of close attention by the military and service industries. Compared with traditional aircraft, quadrotor UAV has good flight characteristics such as vertical take-off and landing, hovering, vertical flight and side flight. Due to its good maneuverability, quadrotor drones have been widely used in aerial photography, power inspection and agricultural production.

Conventional quadrotor UAVs have no forward thrust in a horizontal attitude, and the body must be tilted forward to decompose the lift generated by the four rotors to the horizontal direction to generate thrust. The forward tilt of the quadrotor UAV body will increase the wind resistance area of the fuselage and increase battery consumption. At the same time, the increase in the wind resistance area will also increase the influence of airflow factors on the quadrotor UAV, and the fuselage will easily lose balance. At the same time, due to the overall forward tilt of the drone, when the flight speed changes, the adjustment of the tilt angle of the body is slow, and the response of the body is slow.
