民用运输类飞机最大可用速率抬前轮试飞技术研究

摘要

最大可用速率抬前轮试飞是验证抬前轮速度与起飞安全速度的重要依据，也是难度较大、风险较高的试验项目。以起飞动力学分析为基点，得出最大可用速率抬前轮试飞可能达到的最大迎角，并结合相应的适航审定条款，分析了影响该科目试飞的主要因素，给出了最大可用速率抬前轮试飞技术分析和数据处理方法。%Maximum practicable rotation rate lfight test is the base of verifying rotation speed and takeoff safety speed, and it is very hard to be conducted, and it is also a risky subject. Based on the takeoff dynamic theory, the potential maximum angle in the flight test for the maximun practicable rotation was gotten meanwhile, combined with the airworthiness provisions, the factors that can affect the test were analyzed, and the data processing method of lfight test for the maximun practicable rotation was provided.
