建立了加油机尾流场的等效扰动模型,分析了受油机在尾流场中的飞行安全性。提出的等效气动效应法采用逐点积分方法和加权平均方法,将尾流的非均匀扰动作用转化为受油机运动方程直接可用的平均风速度和等效角速度。给出了尾流作用于受油机的附加力和附加力矩,采用力和力矩平衡方法确定了不同状态下受油机的安全飞行区域。对受油机附加力和附加力矩的仿真结果表明尾流场等效扰动模型和受油机安全飞行区域较好的符合实际情况。
Equivalent perturbation model of the wake field of tanker was established, and the flight safety of oil receiver in the wake field was analyzed. The proposed equivalent aerodynamic effect method uses the point-by-point integral method and the weighted average method to transform the non-uniform perturbation effect of the wake into the average wind speed and the equivalent angular velocity that can be directly used by the receiver kinematics equation. The additional forces and additional torques acting on the oil receiver are given. The safe flight area of the oil receiver under different conditions is determined by the method of force and moment balance. The simulation results of additional force and additional torque on the oil receiver show that the equivalent disturbance model of the wake flow field and the safe flight area of the oil receiver are in good agreement with the actual situation.
