本文介绍一种采用外部推力箱的潜艇武器发射系统。潜艇全少有一个圆筒形鱼雷发射管，发射管的尾向部分位于潜艇的密封壳体内，而其口向部分则位于密封壳体之外。潜艇密封壳体之外装设一个推力箱，可向鱼雷管的尾向部分提供推力水。在鱼雷管的尾向部分和口向部分的周围，有一隔离插件围起一块空间，该隔离插件可以确保封闭空间与密封壳体之外的推力箱柏通，也可保证封闭空间与密封壳之内的尾向部分相通。该插件还可保护鱼雷管不受密封壳体变形的影响，而封闭空间则可把推力水从推力箱输送到鱼雷管的尾向部分。
This article describes a submarine weapon launch system that uses an external thrust box. The submarine has a very small cylindrical torpedo tube, the tail part of the launch tube is located in the submarine sealed housing, and its mouth portion is located outside the sealed housing. A thrust tank is fitted outside the hermetically sealed shell of the submarine to provide thrust water to the rearward portion of the torpedo tube. Around the tail and mouth of the torpedo tube, there is a space around the isolating insert which ensures that the enclosed space is sealed from the thrust box outside the sealed housing and also ensures that the enclosed space and the sealed housing Within the tail part of the interlinked. The insert also protects the torpedo tube from the deformation of the hermetically sealed housing, while the enclosed space delivers thrust water from the thrust box to the rear of the torpedo tube.
