摘　　要：针对六旋翼城市物流无人机RA3在一个旋翼失效后继续巡航的性能参数变化问题进行了研究。综合考虑了无人机的飞行特点,建立了飞行任务剖面各阶段模型,包括悬停、爬升、降落和巡航阶段,通过搭建测试平台和进行试验获得动力参数。模型算例表明:当无人机的一个旋翼失效后继续飞行,剩余工作旋翼的转速和功率均会增大;虽然各个旋翼的功率和能耗有所增加,但是同样的电池电量提供的续航里程与无故障正常巡航时基本相同。In this paper,the problem of how to change the performance of RA3 six rotor urban logistics UAV after one rotor failure was studied.Considered the flight characteristics of UAV,the models of each phase of flight mission profile were established,including hovering,climbing,landing and cruise phases.The dynamic parameters were obtained by building a test platform and conducting tests.The results show that when one rotor of the UAV fails,the speed and power of the remaining rotors will increase.Although the power and energy consumption of each rotor have increased,the cruise range provided by the same battery power is basically the same as that of normal cruise without failure.
