摘要(Abstract)：
为了降低飞机的碰撞风险、提高空域利用率,将碰撞模板优化为长方体与圆柱体的组合形状,更加贴近飞机的真实形态,并在经典EVENT碰撞模型的基础上,将改进后的碰撞模板与平面间隔层结合,分别建立纵向、侧向、垂直3个方向上的改进EVENT碰撞风险模型。最后,引入"翼龙"Ⅱ无人机的相关数据进行Matlab仿真验证,分别运用改进EVENT碰撞模型和经典EVENT碰撞模型对碰撞风险值进行评估对比。结果表明:改进模型能够有效降低计算冗余,减少飞机的碰撞风险;改进模型的碰撞概率约是经典模型碰撞概率的70%,改进模型对飞行碰撞概率的计算更符合实际。研究成果可在相同的安全目标风险条件下,得到更加准确的碰撞概率,为航路科学规划提供科学依据。
