大型民机试飞测试发展与挑战

飞行试验是对飞机的性能进行验证和确认的关键阶段,试飞测试是保障该阶段工作的重要内容；国内目前对于军机已拥有了成熟的测试技术、测试方法和可靠的测试设备,而对于民用飞机特别是大型民机的试飞测试目前还处在起步阶段；随着国家大飞机研制专项的不断推近,大型客机试飞测试需求逐步明确；从大型民机试飞测试需求和测试工作特点出发,对机载测试技术变革、遥测和数据处理技术等键技术在国外的最新发展和国内大型飞机的现状进行对比分析,可以看出我国民机试飞测试在网络化机载测试系统应用、遥测传输链路带宽、大数据快速处理等方面存在较大的挑战；在此基础上对应对挑战的发展策略和后续攻关的方向进行研究,可以为我国大型飞机特别是民机试飞测试技术的发展提供参考。 

Development and Challenge of FTI for Large Civil Aircraft[JZ)][HS)]

Flight test is the key stage to verify and confirm the performance of the aircraft. The Flight Test Instrumentation is an important part of this stage. But the current test equipment depends heavily on foreign suppliers.In response to the call for the innovation of science and technology, to develop the civil aircraft flight test technologysystematically and to improve the civil aircraft flight test ability fundamentally, based on the analysis of characteristics of the flight test instrumentation, also the analysis of the development of foreign test technology and the present situation of domestic technology, this paper presents an overview of the current challenges in the development of technology and the source of the problem. It also puts forward the development strategy to deal with the challenge.And follow-up the research direction.
