飞行试验机载关键参数快速处理系统设计

Design of rapid processing system of flight test airborne key parameters

飞行试验过程中,关键参数的快速处理已成为国内外试飞机构争相解决的重要技术。在试验机的机载实时系统中增加关键参数快速处理单元,不需经过地面原始数据下载及位流分析等操作,利用空中飞行时间,在机上完成部分数据预处理及结果分组存盘,确保试飞工程师在飞行结束后可以直接对数据处理结果进行二次分析。关键参数快速处理单元解决了海量试飞数据处理的技术难题,对提高单次试飞效率及缩短型号试飞周期具有重要意义。

In the flight test course, rapid processing of key parameters is a key technology that remains to be solved in do- mestic and overseas. The rapid processing unit added in airborne real-time systems of a testing flight preprocesses part of data and saves group data by utilizing the time of flight without raw data download and bit stream analysis on ground, ensuring that flight test engineers can directly makes a secondary analysis of data processing results after the flight. The rapid key parameters processing unit solves the technical problem of mass of flight test data processing, and is of great significance for the improve- ment of single test flight efficiency and the shortening of model flight test cycle.
