中文摘要：

根据潜射战术导弹水下垂直运动的过程及特点,建立了导弹在水中及出水阶段的运动数学模型、推力矢量控制模型,分析了导弹水中和出水运动过程中5级海浪对导弹运动姿态的影响。通过仿真计算,得出了潜艇垂直发射战术导弹后,5级海况下导弹水中受控运动和无控运动时出水姿态的变化情况,为研究潜射导弹水中弹道提供了参考。

英文摘要：

The missile motion mathematical model and the thrust vector control model during the underwater state, which are established on the process of the SLTM vertical underwater movement, can be used to analysis the influence on the moving posture by the 5-class sea waves. According to the simulation calculation, the research can be beneficial to the study on SLTM underwater trajectory, respectively shows the variation of the missile exceeding water gesture on the controlled and uncontrolled conditions when the missile is launched by the submarine under the 5-class sea state.
