不同交叉角度下的交叉跑道碰撞风险评估

Intersecting Runways Collision Risk Assessment Based on Different Intersection Angles

交叉跑道能灵活地面对强侧风的影响,从而提高机场的效率和通行能力。通过分析交叉跑道运行的特点,将交叉点作为冲突点进行模型研究,建立基于冲突点的碰撞风险区,构建基于冲突点的交叉跑道碰撞风险模型,并分别对地面与空中两种运行情况下的碰撞风险进行评估。算例结果表明:当交叉角为90°时,3种运行模式下的碰撞风险均小于规定的安全目标水平,当改变交叉角度进行分析,随着交叉角范围从15°~90°变化时,交叉跑道碰撞风险值随着夹角的增加,在30°时碰撞风险值达到最大,随后又减小,当交叉角为75°时碰撞风险达到最小值。

Intersecting runways can flexibly face the impact of strong crosswind,toimprove the capacity and efficiency of the airport. By analyzing the characteristics of intersecting runways operation,take the intersection as a conflict point for model research,established a collision risk zone based on the conflict point,a collision risk model of intersecting runways based on the conflict point is proposed,and the risk of collision both ground and air operations is evaluated. Numerical results prove that when the angle of intersecting runways is 90°,the collision risk under all three operating models are below the level of safety target,when changing the angle of intersecting runways for analysis,as the angle ranges from 15° to 90°,with the increase of intersection angle,the collision risk value of the intersecting runways reaches the maximum at 30°,and then decreases,when the intersection angle is 75°,the collision risk reaches the minimum.
