不同的自航发射装置管体结构参数对鱼雷内弹道的影响不同,综合分析了鱼雷在变截面自航式发射管中的受力情况,建立了自航鱼雷发射的内弹道模型,并对不同结构参数的自航发射管内鱼雷内弹道进行计算机仿真,仿真结果表明,后端管内径大小主要影响鱼雷的出管时间,而前端管管口内径的大小对鱼雷的出管速度和出管时间影响都比较大,前端管内径大小应是自航发射管设计的重点。

Different parameters of swim-out torpedo launcher have different effect on the interior trajectory of torpedo. Based on analyzing the strength condition of the torpedo in variable section swim-out launcher, the interior trajectory of torpedo was modeled. Then, the interior trajectories of torpedo were simulated under the condition of different structural parameters. The result shows that the inner diameter of back section mainly affects time of torpedo swimming out, and the inner diameter of front section affects it's time and speed much. So, the inner diameter of front section should be given much consideration in design.
