摘要: 为研究近距平行跑道(CSPRs)配对进近的侧向碰撞风险,首先,建立运动学方程,描述配对进近飞机的运动过程,确定配对进近飞机之间的时变间隔;然后,通过大涡模拟的方法仿真尾流强度,分析前机尾涡流场特性和后机遭遇前机尾流后的响应机制,构建后机受尾流扰动时的力矩平衡模型,确定尾流安全区域;最后,考虑侧向定位误差,应用概率论基本原理计算和分析侧向碰撞风险。结果表明:CSPRs配对进近过程中前后机之间碰撞风险不断增大并在最后时刻取到最大值,且随初始间隔、正侧风的增大而增大。

Abstract: In order to study lateral collision risk of closely spaced parallel runways (CSPRs) paired approach, a kinematic equation was established to describe motion process of aircraft and to determine time-varying intervals between them. Then, wake strength was simulated through large eddy simulation, wake vortex field characteristics of front aircraft and response mechanism of rear one which was disturbed by wake were analyzed, thus a moment balance model was established to determine safety area of wake. Finally, with lateral positioning error taken into consideration, lateral collision risk was calculated and analyzed by using basic principles of probability theory. The results show that the risk grows continuously during paired approach process and reaches maximum value at the last moment, and it increases as initial interval and positive crosswind increases.

Key words: paired approach, collision risk, wake vortex field, safety separation, positioning error, moment balance
