Abstract

Abstract: 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.Key
