摘　　要：对最小离地速度试飞方法进行了介绍,对试飞数据处理方法进行了研究,总结了最小离地速度试验条件向标准条件换算方法、最小离地速度与推重比的关系以及双发试验向单发状态的换算方法。最后以某型飞机最小离地速度模拟器实验为例,对所给出的方法进行了验证。结果表明,数据处理方法可行有效,可以用于运输类飞机最小离地速度试飞。Describe the flight test process of minimum unstick speed,study on data processing methods,summarize the data reduction means of minimum unstick speed from test conditions to standard conditions,the relationship between minimum unstick speed and thrust-weight ratio,and the method of transferring the two-engine-operating flight test result to the one-engine-operating condition.By performing the minimum unstick speed simulator test of certain type aircraft,it proves that the data processing methods given are feasible and operative,these methods can be used for minimum unstick speed flight test of transport aircraft.
