起飞飞机后侧穿越方式下后机抗侧风能力研究

Research on Anti Crosswind Capability of Rear Aircraft under Mode of Back Crossing of Takeoff Aircraft

为提升机场运行效率,合理减小飞机之间的安全运行间隔,基于起飞飞机后侧穿越方式对后侧穿越飞机的抗侧风能力进行研究。从后机机身受前机喷流影响角度出发,探究了飞机受侧风时最容易被影响的区域,综合考虑飞机几何尺寸、飞机中心位置和侧风速度等因素,构建飞机在低速滑行阶段抗侧风能力模型。并以重庆机场的五种典型机型为例进行实例验证,将实验结果与FCOM手册上的参考数据对比,验证了计算方法的可行性。同时,求解算法具有普适性和准确性,可以广泛运用在不同机型的求解计算中。

In order to improve the operational efficiency of the airport and reduce the safe operation interval between aircraft,the anti crosswind capability of rear side crossing aircraft is studied based on the rear side crossing mode of take-off aircraft.From the point of view that the rear fuselage is affected by the jet of the front aircraft,this paper explores the most easily affected area when the aircraft is affected by the crosswind,and comprehensively considers the geometric size of the aircraft,the position of the center of the aircraft,the crosswind speed and other factors,constructs the anti crosswind capability model of the aircraft in the low-speed taxiing stage.Five typical aircraft models of Chongqing airport are taken as examples to verify the feasibility of the calculation method.The experimental results are compared with the reference data in FCOM manual.At the same time,the algorithm has universality and accuracy,and can be widely used in different models.
