摘　　要：在飞机着陆性能分析问题的研究中,为了有效分析飞机在遭遇微下击暴流情形下的飞行特性以及研究飞机进场着陆轨迹的变化规律,在分析微下击暴流水平风和垂直风特点的基础上,建立了微下击暴流的风切变模型,根据理想化的飞机质点运动方程,提出了运动方程的求解算法;仿真结果表明,不同的风场强度会使飞机着陆轨迹不同程度的改变且飞机受垂直风的影响较明显,在离地高度不同时飞机进场着陆的危险程度也不一样,当处于微下击暴流中心时对飞机的影响最大,同时验证了微下击暴流风切变模型的合理性。In order to analyze the flight characteristics of the airplane in the case of microburst and research the change rule of the airplane landing effectively, a micraburst wind shear model is established based on the characteris- tics of the horizontal wind and the vertical wind. According to the particle motion equation of the idealized airplane, the solve algorithm of the motion equation is proposed. The simulation resuhs show that the different strength of wind field can make the airplane different landing trajectory and the influence of the vertical wind is obvious. The danger degree of landing approach is not the same because of the different altitudes, the danger degree of landing approach biggest value when in the microburst center. At the same time, it is also verified the rationality of the microburst wind shear model and the solve algorithm of the motion equation.
