有没有懂军舰的朋友，知道战列舰的炮管末端的那个蒙皮一般是什么材质的吗？ 第1页

因炮而异。

*Blast Bags/Gun Ports这些词中文用词看个乐，前者似乎约定俗成做炮衣——约定俗成了就不需要理由了，用就行.jpg

Blast Bags, Bloomers or Gun Bucklers - Canvas, rubber or neoprene covers around the barrel of a gun where it enters the gun port. Gun ports by their nature represent holes in the glacis plate of a turret. When the guns are fired, these holes can allow overpressure or "blast" to enter the the turret, which can disrupt the operation of the turret and injure the gun crew. These holes may also permit water to enter the mounting. The use of blast bags over the gun ports provide some measure of protection from these hazards. Also see "Gun Port Shield" below.
防爆破袋/灯笼罩（炮衣）/火炮护罩-遮住一门火炮伸入炮门部分的帆布，橡胶或者合成橡胶（氯丁橡胶）制品。炮门显然代表了炮塔护墙上的开口。当火炮开火的时候，这些开口会导致超压或者“爆破”进入炮塔内，从而影响炮塔的运行或者导致成员受伤。这些开口同样会导致炮塔进水。使用放爆破袋覆盖炮门可以一定程度上提供对这些情况的保护。另见“炮盾”。
Gun Port Shield- Curved armor plate attached to a gun barrel such that it seals the gun port in the glacis plate, regardless of the elevation of the gun. Gun ports are by their very nature weak points in the armor protection of a gun mounting or turret. Gun shields seal these openings and are intended to provide at least some measure of protection from shell splinters. In addition, many gun shields are designed so as to keep water and weather out of the interior of the mounting or turret.
炮（门）盾-连接在炮管上，不计抬升角度总能够封闭护墙的弯曲的装甲板。炮门显然代表了火炮结构或者炮塔上的装甲防御弱点。炮盾封闭了这些开口，也被用于提供一定程度上的对破片的防护。在此之外，还有一些炮盾被设计用来保护炮塔内部不会进水或被天气影响。

评论有说到那么补充一点：

炮(口)塞（Tompion as in UK/Empire, Tampion in US/N.America，也做tampon）：

A block of wood inserted into the barrel of a gun on a 19th-century warship to keep out the sea spray. Also used for covers on the ends of the barrels of more modern ships' guns, the larger of which are often adorned with the ship's badge or other decoration. The term is often bastardized as "tampon".
一种··· ···插入炮管的木塞来避免海水进入。也用于现代战舰的火炮，多数都装饰有船只的舰徽或者其他修饰··· ···也做“tampon”
