摘　　要：为实现潜射导弹出水姿态的快速精确计算,建立了海洋流场模型和潜射导弹出水动力学模型,分析了空化现象对弹体水动力特性的作用,研究了弹体速度,海流速度,波浪高度以及出水相位对导弹出水姿态的影响。研究结果表明,在速度不高于20 m/s的情况下,空化效应对出水过程中导弹姿态的影响较小;弹体速度直接影响导弹受波浪力的作用时间,弹速越低,潜射导弹受波浪力影响越长,出水姿态参数变化越明显;海流流速越大,导弹姿态受扰动越严重,侧向偏距越大;波高影响波浪力幅值大小,对出水姿态参数有着直接的影响,波高越大对出水姿态参数的影响越大;出水初相位和流速主要影响流体质点的运动方向,改变波浪附加惯性力,导弹在波谷和波峰位置出水对导弹姿态影响最大,波节介于两者之间。In order to achieve fast and accurate calculation of the exiting-water altitude of submarine launched missile,a model of ocean flow field and an exiting-water dynamics model of submarine launched missile were established in this paper.Based on which,the effect of cavitation phenomenon on the hydrodynamic characteristics of the missile was analyzed.The effects of missile velocity,ocean current velocity,wave height,and exiting-water phase on the missile exiting-water attitude were studied.The research results indicate that,the cavitation effect has a relatively minor impact on the missile attitude when the speed is less than 20 m/s during the exiting-water process.The action time of the wave forces on the missile is related to the launch velocity.The lower the missile velocity is,the more perturbation of the missile altitude is.The higher the ocean current velocity is,the more severe the disturbance to the missile attitude and the lateral deviation are.The wave height affects the amplitude of wave force and has a direct impact on the parameters of water outlet attitude.The larger the wave height,the greater the impact on the parameters of water outlet attitude.The initial phase and flow velocity of the outflow mainly affect the direction of motion of fluid particles,changing the additional inertial force of waves.The missile’s outflow at the trough and peak positions has the greatest impact on the missile’s attitude,and the wave node is between the two.
