运输机进行局部改装后,其结构和气动外形发生了变化。起飞性能是飞行试验中一项重要考核项目,通过构建基于地面光电测试和机载影像测试的综合测试系统,对飞机起飞过程中一台发动机停车情况下的两种处理方式(即中断起飞和继续起飞)进行试飞测试,精确获取飞机的运动参数。通过对实测参数、运动影像以及机载信号量等信息比对分析,得出试验结果,并对测量结果进行了误差分析。
Transport aircraft for partial modification, the structure and aerodynamic shape has changed. Take-off performance is an important test item in flight test. By setting up a comprehensive test system based on ground-based photoelectric test and on-board image test, two kinds of handling modes of an engine during stopping process, that is, Take off) for flight test, accurate access to the aircraft’s movement parameters. Through the comparison and analysis of the measured parameters, moving images and airborne signals and other information, the test results are obtained, and the error of the measurement results is analyzed.
