摘　　要：无人机飞行试验的故障和事故分析需要完整记录无人机飞行状态及环境信息,为此设计了能够记录无人机遥测/遥控、飞行图像和发动机噪声的机载综合记录仪,并解决了各种信息的同步记录和回放问题,提供了一套完整的解决方案。同时为满足无人机特殊的使用环境,对记录仪进行了小型化、减重设计及电磁兼容设计,结果表明,此记录仪适用于无人机系统,为无人机飞行性能分析及故障事故分析诊断提供了一种有效的支持手段。Complete recording of UAV flight state and environment information is crucial for fault and accident anal- ysis in UAV flight tests. A comprehensive onboard information recorder is designed to record UAV telemetry and tele- control information, flight image and engine noise. A complete solution is provided to record and replay the information synchronously. Also measures are taken to reduce the size and weight of the recorder, and to enhance the electro- mag- netic compatibility. Test result shows that the recorder is applicable for UAV system and it strongly supports the flight per- formance analysis ,fault and accident analysis for UAV system.
