Calculation of reliability index based on mission completion probability for UAV system

摘要: 为计算无人机系统的可靠性指标,论述了现代无人机系统的组成,利用可以收集到的国外无人机外场使用数据,结合无人机系统的不同工作模式,建立了系统的任务可靠性模型,以任务成功概率(MCP)计算为出发点,对无人机系统的平均致命性故障间隔时间(MTBCF)和平均无故障工作时间(MTBF)进行了初步分析计算.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 probability of UAV system was presented, in which the modes and the field statistics data of the UAV system were considered to build the reliability block diagram of the system. Finally, the UAV system's MTBCF (mission time between critical failure) and MTBF (mean time between failure) were calculated and analyzed.
