摘　　要：针对小型无人机等典型"低慢小"航空器(LSS-UAV)在城区黑飞扰航事件频发的问题,开展纤维丝束软毁伤LSS-UAV动力系统效果研究。设计了一种电动机动力测试系统以及试验方案,以某型号电动机为试验对象,研究了纤维丝束对电动机的缠阻作用效应。试验结果表明:150D/3、210D/3、300D/3、20S/3、200D 5种规格纤维丝束对电动机作用的有效转速下降时间在0. 9～1. 5 s之间,1. 0 s内的电动机扭矩变化量在0. 021～0. 039 N·m之间,且拉力变化量在0. 608～1. 300 N之间。通过分析得到了所试材料软毁伤目标动力系统的最优材料参数。Focusing on the frequent occurrence of disruption events of low altitude, slow speed and small unmanned aerial vehicle (LSS-UAV) in the urban area, the effect of soft damage on power systems of LSS-UAV using fiber tow is studied. A motor power test system and a test scheme were designed. The intertwining-block effect of fiber tow on the motor is studied by using a certain type of motor as the test object. The test results show that the effective fall times of rotation speeds of five fiber tows, suck as 150D/3, 210D/3, 300D/3, 20S/3 and 200D, are between 0.9 s and 1.5 s, and the variable quantities of torque and tension within 1.0 s are between 0.021 N ·m and 0.039 N ·m, and 0.608 N and 1.3 N, respectively. The optimal material parameters of the soft damage on target dynamic system in the tested materials can be obtained through analysis.
