飞机着陆进近穿越风切变的轨迹响应

大气紊流和风切变对飞行活动影响较大，尤以低空风切变危害最大，严重威胁着民航飞行的安全。鉴于飞行器对抗大气扰动的实际能力有限，正确的飞行对策是回避或改出危险的大气扰动区。本文对某训练飞机着陆进近遭遇风切变时飞机轨迹的变化进行了模拟仿真计算。结果表明，采用恒定迎角策略，即采用最大允许迎角（抖动迎角）和最大油门时，改出效果最佳。同时计算出了某训练飞机在水平风为0时，所能抵抗的最大垂直阵风强度；以及在垂直阵风为0时，所能抵抗的最大水平风强度。

Trajectory Response of Aircraft Approaching and Landing When Encountering Wind Shear

Atmospheric turbulence and wind shear, especially, low-level wind shear, impact the civil flight safety severely. Because of the limitation of turbulence that flying vehicles can resist, the right choice is to avoid or parry the dangerous turbulence. This dissertation simulates and calculates the trajectory changes of an aircraft in the condition of a trainer encountering wind-shear during ap-proach and landing. As a result, using Constant-Angle-of-Attack Rule which combines maximum an-gle of attack （buffeting angle of attack） with maximum power setting is the best solution of an aircraft to recover from wind-shear. At the same time it calculates the maximum vertical gust the trainers can resist when the horizontal wind is zero and the maximum horizontal gust the trainers can resist when the vertical wind is zero.
