水弹道问题是水下发射技术着重研究的关键问题之一.模拟了全湿流状态下水下飞行器在铅垂面内的有控弹道,并就仿真结果与无控弹道进行了对比分析.分析结果表明,水下飞行器发射时,增加控制作用可以明显地减小俯仰角偏差.

Underwater trajectory is one of the key problems in the process of launching the vehicle.The controllable trajectory of underwater vehicle of no cavity flow on vertical surface is simulated and compared with the uncontrolled trajectory.The result of contrast and analysis shows that adding control can reduce the deviation of pitching angle obviously when the vehicle is launched.
