起飞飞机后侧穿越方式下的滑行效率分析

为提高机场场面运行效率，以前侧跑道穿越方式为比较对象，对后侧穿越方式下的滑行效率进行分析。基于前后侧两种不同跑道穿越方式的机理，结合图论思想，将航空器的地面滑行速度、安全间隔及滑行道使用规则等作为约束条件，以总的地面滑行时间最短为目标函数，分别构建前侧穿越和后侧穿越两种不同穿越方式下的数学模型；根据前后侧穿越方式下的航空器地面滑行特点，设计面向前后侧穿越下航空器滑行路径的遗传算法对模型进行求解；选用重庆江北国际机场为例，统计目前在该机场运行的主要机型，从起飞滑跑距离、抗侧风能力及尾喷影响距离对其性能进行分析，计算江北机场某一天高峰小时内37架航班的地面滑行时间，比较两种穿越模式下的滑行效率。计算结果表明:单位小时内，前侧穿越结合后侧穿越模式比单独使用前侧穿越模式时的总地面滑行时间节省约9min，结合使用前侧穿越和后侧穿越的模式可以在前侧穿越延误较大的情况下提高场面滑行效率。

Taxiing Efficiency of the Way of Crossing the Runway at the Back Side of the Takeoff Aircraft

In order to improve the efficiency of airport surface operation, taking the front side runway crossing mode as a comparison, the taxiing efficiency under the back side crossing mode is analyzed. Firstly, based on the principle of two different runway crossing modes and the graph theory, the ground taxiing speed, safety interval and taxiway usage rules of the aircraft are taken as the constraint conditions, and the total ground taxiing time is regarded as the objective function. The two different crossing modes are designed. Then, according to the characteristics of aircraft ground taxiing under the front and back side crossing mode, and the genetic algorithm is designed to solve the model of the aircraft''s taxiway. Finally, Taking Chongqing Jiangbei International Airport as an example, the main types of planes operating at the airport are counted, and the performance of the take-off run distance, the anti-crosswind capability and the tail spray influenceperformance of the take-off run distance, the anti-crosswind capability and the tail spray influence distance is analyzed. The ground taxiing time of the flight is calculated at Jiangbei airport. And thetaxiing efficiency under the two crossing modes is compared. The calculation results show that the combination of front and rear crossing mode can save about 9 minutes compared with the front side crossing mode in one hour. The mode of front crossing and back crossing can be combined to improve the surface taxiing efficiency when the front crossing is delayed a lot.
