摘　　要：ARJ21-700飞机的最小离地速度测量是FAA适航取证的关键考察科目,属于高风险科目。首次采用光电测量技术对ARJ21-700飞机的最小离地速度试飞科目进行测量,对采集的数据进行判读、脱靶量修正、数据异常值识别、目标航迹参数解算、数据平滑滤波、目标速度参数解算等,并进行试验结果数据的误差分析。试验结果表明,采用的方法满足该试飞科目要求,并可在同类飞行试验课题中推广使用。ARJ21-700 minimum unstick speed flight test is a key subject in flight test for FAA airworthiness certification, belongs to high-risk subject. This is the first use of optical measurement technology for minimum unstick speed measurement of ARJ21-700 aircraft. The graph is judged, miss distance is corrected, outliers are identified, target track parameters are solved, data are smoothed, target speed parameters are solved. The errors of test results are analyzed. The test results show that above method can meet the requirements of minimum unstick speed flight test.
