摘　　要：为解决空中交通拥塞,保证航空器在自由飞行环境下的飞行安全,综合考虑高空风、CNS性能和机载防撞系统等3种飞行环境因素,建立了基于概率的碰撞风险模型。根据给定安全目标水平,利用泰勒级数对碰撞风险模型进行有效展开,求解自由飞行条件下最小安全间距。算例验证表明,所建立的碰撞风险模型计算结果与现有数据结果相符,模型具有可行性。To reduce air traffic congestion and ensure flight safety, it is necessary to study the various factors influencing the air- craft flight safety. Thus, a collision risk model with three types of flight environment factors including wind, CNS performance, and collision avoidance system, was developed. Under the given level of route safety goal, the mathematical model was evaluated with Taylor series expansion. The minimum safety distance under free flight was also obtained. Numerical verification indicates that thecollision model matches well with the existing data, which proves the effectiveness of this model.
