The invention relates to an unmanned aerial vehicle power system and an unmanned aerial vehicle. The unmanned aerial vehicle power system comprises a plurality of ducts (1) containing rotor wings, thebottom end of each duct is connected with an airflow pipe (2); each airflow pipe comprises a main pipeline (21), a first branch (22) used for exhausting and a second branch (23) extending towards theother airflow pipes. Wherein an opening in the tail end of the first branch is downward, valves (231) capable of being opened and closed are arranged in the second branches, the multiple second branches are selectively communicated through the valves, and the unmanned aerial vehicle power system further comprises a control device used for controlling the valves to be opened or closed. In a normalworking state, each valve is in a closed state; when any duct breaks down, the control device controls all the valves to be opened, so that airflow generated by the ducts which do not break down is evenly distributed into all the airflow pipes, the posture of the unmanned aerial vehicle is stable until the unmanned aerial vehicle lands safely, and the situation that the unmanned aerial vehicle flies unstably and cannot land safely due to the fact that any rotor wing breaks down is avoided.

    本公开涉及一种无人机动力系统和无人机,无人机动力系统包括多个容纳有旋翼的涵道(1),每个涵道的底端分别连接有气流管(2),每个所述气流管包括主管路(21)、用于排气的第一支路(22)和朝向其他所述气流管延伸的第二支路(23),其中第一支路的末端开口向下,第二支路中设置有可开闭的阀门(231),多个第二支路通过阀门选择性连通,无人机动力系统还包括用于控制阀门开启或关闭的控制装置。正常工作状态下,各个阀门均处于闭合状态;任一涵道出现故障时,控制装置控制各个阀门开启、以使未发生故障的涵道产生的气流均布至各个气流管内,使无人机姿态稳定直至安全降落,避免因任何一个旋翼处的故障而导致无人机飞行不稳定、不能安全降落。
