The invention relates to an unmanned aerial vehicle rotor wing protection device and an unmanned aerial vehicle. The unmanned aerial vehicle rotor wing protection device comprises a protection cylinder and an air inlet adjusting assembly. The two ends of the protection cylinder are provided with communicating openings, the protection cylinder is used for being installed at a rotor wing of the unmanned aerial vehicle, and the rotor wing is located in the protection cylinder. An air inlet adjusting assembly is arranged at one end of the protection barrel, an air inlet channel is formed in the protection barrel, airflow in the protection barrel can enter the air inlet channel, the air inlet adjusting assembly communicates with the air inlet channel, and the air inlet adjusting assembly can stretch out and draw back under the action of air pressure so that the size of an opening in one end of the protection barrel can be adjusted. Airflow generated by the rotor wings is used as power to push the air inlet adjusting assembly to stretch out and draw back, then the size of an opening in one end of the protection barrel is adjusted, the lift force of all the rotor wings in the unmanned aerial vehicle can be adjusted, distribution of the lift force can be adjusted, the unmanned aerial vehicle obtains better flight stability, steering control is improved, and the unmanned aerial vehicle is more stable. And the unmanned aerial vehicle can conveniently fly under the condition of complex crosswind.
本发明或涉及一种无人机旋翼保护装置及无人机,无人机旋翼保护装置包括保护筒以及进风调节组件。保护筒的两端均设置有相连通的开口,保护筒用于安装在无人机的旋翼处,且旋翼位于保护筒内。保护筒的一端设置有进风调节组件,保护筒上设置有进风道,保护筒内的气流能够进入到进风道,进风调节组件与进风道连通,进风调节组件能够在气压的作用下伸缩,以实现调节保护筒一端开口的大小。利用旋翼产生的气流作为动力来推动进风调节组件来伸缩,进而实现调节保护筒一端开口的大小,就能够调节无人机中各个旋翼处升力的大小,调整升力的分布,让无人机获得更好的飞行稳定性,改善转向操控,便于无人机在侧风复杂的情况下进行飞行。
