摘要
在新型飞机飞行试验任务中,遥测监控技术是保证试飞安全,提高试飞效率的重要手段;针对目前地面实时监控技术面临的问题和挑战,提出采用基于故障树的多类型告警技术、试飞任务的嵌入式准实时数据处理技术及应急处置辅助决策技术等先进监控技术,引入试飞安全决策库理念,建立应急处置辅助决策机制,构建飞行试验综合安全监控系统,实现飞机各系统试飞状态监控和综合故障告警、复杂试飞科目的准实时计算评估和应急处置决策支持;实际飞行试验结果表明,应用此技术开发的综合安全监控系统,可以使试飞指挥员和工程师在第一时间及时准确地获取试验机故障告警、试飞科目评估结果和应急处置决策方案,极大地提高了试飞效率和安全性。
In the new aircraft flight test mission,telemetry monitoring technology is an important means to ensure flight test safety and improve flight test efficiency.Aiming at the challenges and problems of terrestrial real-time monitoring technology,some advanced monitoring technology such as multi-type alarm technology based on fault tree,embedded quasi-real-time data processing technology and emergency treatment auxiliary decision technology are proposed.The flight safety decision library concept is introduced and the emergency treatment auxiliary decision mechanism is established to achieve the aircraft system test flight status monitoring and integrated fault alarm,complex flight test subjects quasi real-time calculation and evaluation and emergency response decision support.The results of the actual flight test show that the integrated monitoring system developed by this technology can make the test flight commander and engineers get the test aircraft fault alarm,the evaluation results of test flight subjects and the emergency decision-making plan in the first time,which greatly improves the test flight efficiency and safety.
