Comprehensive Record Of The Flight Data Analysis Technique

With the development of aviation technology and the important of flight data gradually, FDMRS become the important technology of development in the next generation military aircraft. The Comprehensive Record and Analysis Technology of flight data is the important part of FDMRS. Also it is necessary to realize FDMRS.Incorporated with the tenth-five project of air force —The Intelligent Cabin Show Controlling and Flight Data Management Record Technology, the paper investigate the key technology of FDMRS that is the Comprehensive Record and Analysis Technology of flight data. Based on the analysis, the thesis designed the system that deal with all flight data and display these.The thesis firstly analyzed the requirement of new generation FDMRS and the system characteristics, which emphasized on its framework and data attributes. With the analysis, the paper designed the system framework and data structure.It is necessary to compress the data especially for AV data and radar image before its storage and transmitting because a great deal data were used in the system. For recording these data, the paper discussed flight data compress technology, which mainly focused on MPEG - 4 technology. Also the thesis discussed other compress algorithms for radar image.Owing to complexity and real-time of flight data, the thesis discussed the technology of distributed acquisition and concentrative storage. It achieved real-time request and general management.Also the paper researched data coding and analyze technology. Due to the deficiency of data management, the paper put forward the criterion database that can manage all data effectively. And on the basis of these technologies, the thesis gave the new application direction of flight data.The task that investigated FDMRS is very big. After all work had done, the paper focused on analyzing the flight data display technology, which was one part of the whole system.The research indicates the key technology has had the important meaning to realize the system, and has had stronger application value.
