摘　　要：本文针对航行体水下喷管摆动推力矢量控制动态过程,建立了流体动力与弹道耦合数值仿真计算模型,采用CFD手段分析了航行体水下运动过程中喷管尾部喷流流场与尾空泡相互作用流场的发展演化过程,获得了航行体摆动喷管推力矢量控制下非定常流场动态特性,为航行体水下运动控制方式的深入论证及应用提供了研究方法和手段支撑。The numerical model which could consider the swing of a nozzle and the hydrodynamic calculation of a vehicle was established. The features of the surrounding flow field and underwater trajectory of the vehicle were investigated based on the multiphase model, dynamic mesh and UDF(user-defined function) technique. After realizing the swing of the nozzle in a moving object and stable calculation in deep-water simulation, the control process of the pitching angle and the interaction between the gas jet and the base cavity of the vehicle were analyzed.
