Abstract: To improve runway utilization, the problem of building runway high-speed exit on old airfield which flight area shape like “目”has been studied systematically. Through analysis the process that airplane taxing in the runway high-speed exit，influencing factors which are distance between the runway and taxi way and between two mid-taxing way are founded. Based on this，the math model which for the distance that runway high-speed exit need is built and limiting condition that is distance along runway is demonstrated，then the curves between airplane taxing speed and distance from the runway to taxi way and runway high-speed exit need are obtained for representative airplane, when degree of runway high-speed exit angle is 30°，45°, and 60°. At last, using the paper’s result, the feasibility of building runway high-speed exit on a certain airfield is analysed, and the rebuilding scheme for runway high-speed exit is put forward.

摘要： 为提高跑道的利用率，对飞行区布局为“目”字形状的机场改建快速出口的问题进行了系统研究. 分析了飞机在快速出口中滑行的过程，得出了跑滑间距和中间联络道之间的可用距离为限制“目”字形机场改建快速出口的影响因素. 在此基础上，建立了快速出口距离的数学模型，分析了现有机场改建快速出口时沿跑道方向的限制条件，得出了典型飞机在不同机场运行时快速出口角度为30°、45°、60°条件下，飞机滑行速度和跑滑间距及快速出口距离之间的关系曲线. 最后应用本文所得的结果对某机场使用两种飞机情况下改建快速出口的可行性及限制条件进行了分析，提出了改建方案.
