机场快速出口平面设计是机场规划设计的重要组成内容之一,但供小型飞机使用的机场快速出口平面设计目前尚无系统规范的方法。为建立系统的机场快速出口平面设计方法,本文对典型机场快速出口平面组成进行了系统分析,确定了决定快速出口平面形式的设计参数。以飞机弯道运行安全为准则,确立了快速出口的弯道半径、出口角度和增补面的设计方法。以典型飞机为对象,采用相应参数对飞机的转弯规律进行了模拟计算,得到了5种不同飞机以10、15、20、25和30m/s速度转弯时,出口角度与跑滑间距、出口距离和转弯偏移量之间的关系,为军用机场快速出口设计提供了重要参考。

The design of speedy exit runways for an airfield is an important problem in airport engineering. For the civil aviation, the specifications of FAA and ICAO can be used. But for an airfield used by small airplanes, some problems will crop up. From an analysis of the representative plane of the speedy exit, it is shown that it can be divided into two segments: the turnoff and the fillet. The part of the turnoff can be described by the turning radius and the turning angle, the other part of the fillet can be described by the offset of the airplane. So these are the parameters to be studied. Through analyzing the landing track of the airplane on the runway, the relations between the exit angle and the distance of the runway to the taxiway, and between the offset in the fillets and the distance of the exit are obtained for 5 types of airplanes making swerves at the speeds of 10,15,20m/s,25 and 30. In the end, the paper put forward a new design method for the radii R, the exit angle and the fillet, for the design of speedy exit runways of military airfields.
