摘要
针对紧密编队飞行过程中产生的尾涡流场对空中加油机产生扰动影响的问题,建立了受油机扰动运动模型。将风扰动主要分解为大气紊流和加油机尾涡,分别建立工程化的Dryden大气紊流模型和尾涡模型,将叠加的2个扰动加入到受油机的非线性刚体运动方程中,并对受油机扰动运动进行仿真分析。仿真结果表明:该叠加的方法能够简单有效地模拟反映复杂的气流扰动,为进一步研究空中加油控制系统提供参考。
Trailing vortex is come into being during the close formation flight, which will truly influence the aerial refueling. The receiver aircraft disturbance modeling is aimed for solving this problem. One account of the wind influence of both atmosphere disturbance and trailing vortex of tanker aircraft, the engineering Dryden atmospheric disturbance model and trailing vortex model were built. Then the two superposed turbulences were introduced into the nonlinear rigid body equations of motion to simulate the perturbation motion of receiver aircraft. The result shows that the superposition method can easily and effectively simulate the complicated wind disturbance. The study can provide reference for further research of the aerial refueling control system.
