摘　　要：随着通用航空的快速发展,通航飞行器数量不断增加,空域容量的有限性使得空中交通运行风险增大,因此评估航空器碰撞风险至关重要。论文基于拼接四棱锥碰撞盒建立不同高度交叉航路改进Event碰撞风险模型,并类比推导基于椭球体碰撞盒、圆柱体与长方体组合碰撞盒在不同高度交叉航路的碰撞风险。之后采用广义帕累托分布计算其侧向重叠概率。最终采用塞斯纳172和运5B两种机型作为算例计算并与其他模型进行对比分析,结果表明论文所提模型计算得到的碰撞风险值最小,在满足安全目标水平的前提下具有更高的精度。With the rapid development of general aviation,the number of navigable aircraft continues to increase,and the limited airspace capacity increases the operational risk of air traffic.Therefore,assessing aircraft collision risk is crucial.This article establishes an improved Event collision risk model for cross flight routes at different heights based on the concatenated pyramid collision box,and analogically deduces the collision risk of cross flight routes at different heights based on ellipsoidal collision boxes and cylindrical and rectangular combination collision boxes.Afterwards,the generalized Pareto distribution is used to calculate its lateral overlap probability.Finally,two types,Cessna 172 and Yun 5B,are used as examples for calculation and compared with other models.The results show that the collision risk value calculated by the proposed model in this paper is the smallest,and it has higher accuracy while meeting the safety target level.
