摘要
为找到可操作的空域规划碰撞风险计算方法,基于空域规划参数,改进原有模型,建立航段上每飞行小时飞机的碰撞风险模型。首先,分析空域规划过程中终端区空域和航路巡航阶段航迹夹角0~180°情况下的碰撞风险;然后,将碰撞风险表示为来源于一条航段上飞机的碰撞风险和来源于其他多条航段上飞机的碰撞风险之和,建立碰撞风险模型;最后,将终端区空域规划中的相关参数值输入到该模型,计算2种方案的碰撞风险,并分析碰撞风险随参数的变化趋势。研究结果表明:在已给定其他参数值的条件下,碰撞风险随所需导航性能(RNP)数值、航段起始点高度以及航段起始点的纵向标称距离的增加(垂直标称距离减少)而增加,随着航迹夹角和飞行梯度的增加而减小。因此,可利用该模型计算并分析不同方案的碰撞风险。
To provide an operational collision risk calculation method to be used in the process of airspace planning,the collision risk per flight hour on flight segment was researched.The existed models were improved based on airspace planning parameters.Firstly,collision risk was analyzed when the angle between two flight segments changes from zero degree to 180 degrees in terminal area airspace and on the air-ways.Secondly,the collision risk on flight segment was expressed by the sum of the collision risk stemming from this flight segment,the other risk stemming from other flight segments,and a collision risk model was built.Finally,when the values of the parameters related to terminal area airspace planning were input into the model,collision risks of two situations were calculated,and changing trends of collision riskwith parameters were analyzed.The results show that when other parameter values are given,the collision risk will increase with the increasing Required Navigation Performance value,altitude（decreasing nominal vertical distance） at different initial points of flight segment and nominal longitudinal distance（decreasing nominal vertical distance） at initial points respectively,and the collision risk will decrease with increasing angle between tracks and flight gradient respectively.In conclusion,by using the model the collision risks between aircraft for different airspace planning programs can be calculated and analyzed.
