| 摘 要： | 典型尺度的雷暴低空风切变以长周期振动频率激励飞机,使其偏离预计下滑航迹.在正弦风切变假定下,利用计算机计算和飞行模拟器模拟研究了长周期振动频率上下的正弦波风切变对飞机着陆航迹的影响.结果表明,计算机计算与飞行模拟器模拟得到的飞行航迹并不完全一致,说明用现有模拟飞行器模拟模式训练飞行员处置雷暴低空风切变是不全面的.

| Abstract: | A typical low-level wind shear of thunderstorm activates long periodic oscillation of an aircraft, causing tracking deviation of the aircraft. On the assumption that the wind shear is sinusoidal, the effects of long periodic oscillation on the landing path of an aircraft were studied by computer calculation and with flight simulator. It is shown that the results obtained by calculation and simulation are not the same, implying that it might not be adequate to train pilots to manoeuvre the aircraft in low-level wind shear fully based on the available simulating modes of flight simulators. |
