摘　　要：基于高原环境,详细分析了飞机高原机场着陆过程,将着陆过程分为下滑、拉平、接地和着陆滑跑四个阶段,建立飞机着陆性能模型。为满足模型精度要求,针对飞机飞行速度与综合摩擦系数的函数关系,对飞机着陆滑跑模型做进一步改进,通过仿真验证,表明改进后的模型能够满足模型精度要求。并针对所建立的基于高原机场飞机着陆滑跑距离模型,分析海拔高度、飞机着陆质量以及风速等影响因子对着陆滑跑距离的影响。仿真表明,所建立的飞机着陆模型适用于高原机场,模型精度较高,具有一定的参考价值。Based on the plateau environment, the landing process of the aircraft Plateau Alienort is analyzed in detail, and the landing process is divided into three stages, namely, approach, leveling and sliding. In order to meet the requirement of the model accuracy, the tunction relationship between the flight velocity and comprehensive coefficient of friction of aircraft landing slip stop segment model is further improved, through the simulation, the average relative error of the three roll stage running distance of the measured data and simulation results from down, show that the improved model can meet the requirements of the accuracy of the model. Plateau Airport Landing Distance Based on the model proposed in this paper for further analysis, the altitude, the aircraft landing quality and wind speed and other factors to influence the landing distance, the simulation found that the airport altitude of aircraft landing distance the influence of non-linear relationship, and the quality and speed of aircraft landing of aircraft landing taxiing impact there is a linear relationship between the distance. In this paper, the aircraft landing model is applicable to the Plateau Airport, the model has high precision, and has certain reference value.
