According to the air trajectory of every rocket-assisted torpedo part, we establish an equation group of air vertical motion, improve the in-air trajectory model, and simulatively calculate the polynomials of firing distance and flight time,and firing distance and shut down time. Making use of the polynomials, we calculate the cooperative time of formation salvo of torpedoes, and determine command ways for different situations. The result may facilitate the research of operational application of rocket-assisted torpedo.

根据火箭助飞鱼雷空中运动各部分的特点，建立了其空中纵向运动方程组，完善了空中弹道模型，仿真计算了射程-飞行时间和射程-关机时间关系多项式，利用关系式计算了编队齐射火箭助飞鱼雷的协同时间，确定了不同态势下的指挥方式，为深入研究火箭助飞鱼雷编队作战使用问题提供了重要的参考数据和理论依据。

Then a dynamic inversion tracing control method and a dynamic inversion fuzzy integrated control method are used to design depth control systems for a torpedo respectively. The simulation results illustrate that dynamic inversion fuzzy integrated control method can solve the problem of torpedo depth control more satisfactorily than the dynamic inversion tracing control method can.

提出了基于动态逆的跟踪控制方法和动态逆模糊集成控制方法，并分别将这两种方法用于鱼雷深度控制中，通过仿真说明动态逆模糊集成控制方法比基于动态逆的跟踪控制方法更好地解决了鱼雷的深度控制问题。

When a torpedo or contact mine explodes under the bottom of the ship, the result is widespread serious damage to structure and machinery in the affected area, since it is impracticable to provide the necessary torpedo-protection layers underneath the ship to completely guard against this type of attack.

当鱼雷或是触发引信水雷在舰底爆炸时，损害将会广泛传播并对该区域的舰体结构和机械设备造成巨大的伤害，这是因为在舰底不可能布置所需的鱼雷防护系统来抵御伤害。

Torpedo Guidance and Control System is an important part of torpedo whose performance will directly influence torpedos battle performance.

鱼雷制导系统是鱼雷的重要组成部分，其性能的好坏直接影响到鱼雷的整体作战性能。

The double-color method and theory for stereodisplay of the torpedos trajectory are presented in this article. Program which is using the programming language of Visual C++6.0+MFC+OpenGL has been compiled. In this program, torpedo can be displayed in stereodisplay mode, which can be controlled adapting to the changing of time and space. The final data can easy be simulated and calculated. This method is meaningful to torpedo trajectory design and research.
