摘要
通过建立飞机地面滑跑起飞全过程的运动方程,并结合适航条例规定,给出了一种确定民机最小离地速度的工程计算方法;参照失速速度修正方法给出了受俯仰操纵效能限制的飞机最小离地速度的修正方法;分析了单发失效及不同抬前轮时间对飞机起飞性能的影响。仿真计算表明,所给出的方法是合理的。
This paper presents an engineering method to determine the minimum unstick speed with the aircraft＇s take-off equations of motion and provides the emulational results, according to the Federal Aviation Regulations 25. The method of modifying the minimum unsticks speed for airplanes having the limited pitch control authority is also given referring to the method of modifying the stall speed. In addition, the effects of rotation speed and one engine failure on the take-off performances are also analyzed. The methods mentioned can serve as a reference for flight test researchers.
