潜艇自航发射鱼雷的若干问题

Some problems about self-propelled torpedo launching in submarine

潜艇自航发射鱼雷可以降低发射过程的辐射噪声,有利于提高发射艇的安全性。通过分析自航发射需具备的基本条件、现有533mm口径潜艇鱼雷发射管实现自航发射的可能性、后端补水的自航发射、有动力后端补水的自航发射等几个问题,得出了533mm口径的潜艇鱼雷发射管不可能实现自航发射的结论。另外,对降低潜艇发射鱼雷时的出管速度给鱼雷和发射艇带来的风险作了分析,得出了为保证潜艇发射鱼雷时的安全不能随意降低鱼雷出管速度的结论。

The self-propelled torpedo launching in a submarine can not only reduce noises emitted in the launching process, but also improve the safety of firing torpedoes from the submarine. Based on the analyses of essential conditions of self-propelled launching, the feasibility, back-end water reple- nishment and power-driven back-end water replenishment of self-propelled launching, a conclusion was drawn that the 533-calibre torpedo tube in the submarine cannot make a self-propelled launching. Besides, the analysis of the risk of reducing the velocity at which the torpedo is fired from the exit tube shows that the velocity at which the torpedo is launched from the exit tube can not be decreased at random to secure the submariners torpedo.
