【摘要】 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。更多还原

【Abstract】 A method for measuring the takeoff performance of aircraft in flight test is presented.The configuration and aerodynamic shape are changed after the aircraft is refited.During takeoff,in case of single engine of the aircraft failure,two kinds of treatments(i.e.rejected takeoff and continued takeoff) are tested by means of establishing integrated test system based on ground photoelectric test and airborne video test.The aircraft motion parameters are accurately obtained.With the analysis of the actual measured parameters,motion video and airborne semaphore,the results are obtained.Additionally,the error analysis of the results is made.更多还原
