| Abstract: | In order to solve the problem of the reliability index determination of the UAV (unmanned aerial vehicle) system, the function of the modern UAV system was described. And a practical calculating method for the mission completion probabi lity of UAV system was presented, in which the modes and the field statistics da ta of the UAV system were considered to build the reliability block diagram of t he system. Finally, the UAV system's MTBCF (mission time between critical failur e) and MTBF (mean time between failure) were calculated and analyzed. |
