摘要 适航审定是大飞机研制中的关键环节,试飞测试是适航审定任务实施的重要基础;纵观国内外大飞机飞行试验均非常重视机载数据实时处理;在C919型号中对机载数据实时处理系统进行了研究,以VXWORKS嵌入式实时操作系统为平台,通过对现有机载实时处理系统功能模块进行整合以及软件优化设计来提高C919机载数据实时处理系统性能;经飞行验证,该系统能够实时完成110MB/S网络数据接收、存储、处理、转发和关键参数快速分组处理;对比传统设计能够更好地确保系统数据处理实时性,为保障大飞机试飞安全、提高试飞效率提供技术支撑。 Airworthiness certification is a key link in the development of large aircraft.Flight test is an important basis for the implementation of airworthiness certification tasks.Throughout the flight test of large aircraft at home and abroad,real-time processing of airborne data is very important.The real-time processing system of airborne data is studied in C919.Based on VXWORKS embedded real-time operating system,the performance of C919 airborne data real-time processing system is improved by integrating the function modules of the existing airborne real-time processing system and optimizing the software design.Flight validation shows that the system can receive,store,process,forward and process the 110 MB/S network data in real time.Compared with the traditional design,it can better ensure the real-time processing of system data,and provide technical support for ensuring the safety of large aircraft flight test and improving the efficiency of flight test.
