加油机尾流场建模与仿真分析

提出了等效气动效应法,建立了加油机尾流场的等效扰动模型。等效气动效应法采用逐点积分方法和加权平均方法,将尾流的影响等效为受油机运动方程直接可用的平均风速度和风梯度。对不同状态下受油机所受尾流的扰动作用进行了仿真。结果表明,扰动模型与实际情况比较符合。

Modeling and Simulation of the Tanker's Wake Field

A computing method with principle of pneumatic effect equated is presented and then an equivalent disturbance model of the tanker's wake is developed.In the computing method,the techniques of point-by-point integration and averaging schemes with weight are employed,and the effects of the tanker's wake acting on the receiver aircraft are approximated with effective wind components and wind gradients which can be directly used in the receiver's standard motion equations.The simulation of the wake's affects on the receiver shows that the equivalent disturbance model accords with the facts well.
