Abstract

The invention discloses a pitch changing type rotor wing set applied to an unmanned aerial vehicle and belongs to the technical field of unmanned aerial vehicles. The pitch changing type rotor wing set comprises a rotor wing set body and a pitch changing device, wherein the rotor wing set body includes multiple rotor wings. The multiple rotor wings are rotationally fixed to the pitch changing device, and the pitch changing device is movably connected with all the rotor wings in the rotor wing set body so that the pitch changing device can drive one or more rotor wings to rotate to control the pitch of the rotor wings. A center vertical shaft of the pitch changing device is perpendicular to the rotor wings. According to the pitch changing type rotor wing set, the pitch changing device is arranged so that the pitch changing device can be used for driving one or more rotor wings to rotate, and the pitch of the rotor wings is controlled; and the pitch changing type rotor wing set has the beneficial effects of being simple in structure and wide in applicability.

Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicles, and in particular relates to a pitch-variable rotor assembly applied to unmanned aerial vehicles. Background technique [0002] Unmanned Aerial Vehicle (English abbreviation: Unmanned Aerial Vehicle) is an unmanned aircraft that is controlled by radio remote control or by its own program. [0003] Most of the UAVs in the prior art are electric UAVs, which mainly use main components such as batteries, ESCs, motors, flight controllers, and propellers. The pitch control of the UAV rotor is realized by changing the speed of each propeller. However, due to the limitation of battery energy density, this type of electric UAV generally has a very short flight time and has the disadvantage of poor endurance performance, and the method of simply increasing the number of batteries to improve its flight time will also be greatly improved. reduce its load capacity. Therefore, it has become ...
