摘　　要：为了提高近距平行跑道容量,针对配对进近中配对前机错误闯入配对后机航迹的情况,根据两机的相对运动关系设置速度、距离、角度等参数,建立平面直角坐标系,在此基础上构建了配对进近避让程序模型来计算配对进近安全前界。以上海虹桥国际机场为例,利用蒙特卡洛算法对避让程序模型进行仿真,计算了不同机型配对在多种闯入角度和避让角度组合下,不同跑道间距下的安全前界。仿真结果表明,配对两机的安全前界与跑道间距、闯入飞机的闯入角、两机的速度差有关。该方法可以准确计算近距平行跑道配对进近方式下配对两机的安全前界。This paper intends to briefly introduce the concept and the operation mode of the paired approach and collision-safety boundary of the paired two airplanes. On account of the situation in which the leading airplane intrudes the entering course of the rear one by mistake,the paper has built up a model known as the paired approaches’ avoidance procedure to work out the collision-safe boundary of the paired airplanes based on the 5 steps to set up the parameters to determine the boundary( e. g.,the speed,the distance,the angle,et. al.) according to the relative movement status-in-situ between the paired airplanes,which can help to increase the capacity of the closely spaced parallel runways. And,then,taking Shanghai Hongqiao airport as a case study sample,we have simulated the avoidance program model and calculated the collision-safe boundary of the different runway spacing under the different combination modes of the intrusion angles and avoidance angles at the different runway spacing in accordance with the Monte Carlo algorithm. The calculation above ends up at the distance between the paired airplanes being less than 500 feet. In other words,the paired airplanes are supposed to get close to the collision,with the corresponding space between the paired ones getting near to the collision-safe boundary. The results of our simulation show that the factors that affect the collision-safe boundary of the paired airplanes should be the runway spacing,the intrusion angle of the front airplane,and the velocity gap between the two. Actually,the smaller the runway spacing is,the greater the collision-safe boundary is required for the paired ones. And,in turn,the less the intrusion angle of the leading airplane,the less threat it would bring about to the following rear one,and,in turn,the less the collision-safe boundary of the paired airplanes are needed to keep up. And,in similar ways,the greater the speed difference between the 2 airplanes is needed,the greater the collision-safe boundary of the paired airplane need to
