摘　　要：着陆是飞机在运行过程中的一个重要阶段,着陆分为手动着陆和自动着陆。具备自动着陆能力的飞机可以适应更多的运营场景,极大地增加了飞机的市场竞争力。经过调研,与自动着陆性能要求相关的适航标准大多为概率指标。为验证自动着陆系统是否满足适航条款中的性能要求概率指标,需要进行大数量级蒙特卡罗仿真,并且需要设置与实际飞行场景概率模型相一致的干扰因素概率模型。根据自动着陆相关适航要求捕获自动着陆需求,并采用QFD工具进行二次转化将需求转化为自动着陆仿真的三点功能要素,分别为概率分布拟合、仿真次数确定以及蒙特卡罗计算方法,针对这三点功能要素采用QFD亲和图等方法对解决方案进行整理分类,进而采用交叉验证法、正交试验法等方法确定最终的解决方案。针对最终方案进行自动着陆系统仿真,确认自动着陆蒙特卡罗仿真方法的可行性。Landing is a crucial phase during an aircraft's operation,which is divided into manual and automatic landing.Aircraft equipped with automatic landing capabilities can adapt to a wider range of operational scenarios,significantly enhancing their market competitiveness of the aircraft.Through research,it has been found that airworthiness standards related to automatic landing performance are mostly probabilistic indicators.To verify whether an automatic landing system meets the performance requirements of the airworthiness criteria's probabilistic indicators,extensive Monte Carlo simulations need to be conducted,and the probability model of interference factors needs to be set to be consistent with the actual flight scenario probability model.Capturing the requirements for automatic landing based on relevant airworthiness criteria,and using quality function deployment(QFD)tools,these requirements were transformed into three key functional elements for automatic landing simulation:probability distribution fitting,simulation iteration determination,and Monte Carlo calculation method.These three functional elements were organized and categorized using tools like QFD affinity diagrams.Further methods such as cross-validation and orthogonal experiments were employed to determine the final solution.The chosen solution was then applied in the simulation of an automatic landing system to confirm the feasibility of the Monte Carlo simulation method for automatic landings.
