阿姆斯特朗巡洋舰上的齐射装置
本帖最后由 STG44突击步枪 于 2015-8-1 23:53 编辑【前部舰桥内设有装甲司令塔，钢制装甲的厚度达51毫米，内有液压助力的舵轮、通往轮机舱的传话筒、通过电击发进行齐射的指挥仪，以及通往各个部门/舱位的传声筒等设备。】
【“致远”级军舰这5门大口径火炮可以用特殊的电发装置实现齐射，司令塔内的军官只需按一下按钮，就能出现“万炮齐发”的壮观场面】
最近看到有人在吹这玩意，实际上此齐射（Broadside firing）非彼齐射（Salvo），不过是帆船时代的遗物罢了
和我在http://www.warships.com.cn/thread-6763-1-1.html 说的一样，齐射的前提，是将各炮的方位角和高低角，相对同一个参照系进行统一。
斯科特的回忆录中，对此射法的描述。
The principle of laying guns parallel and firing them simultaneously is not new ; I was taught it in the first ship in which I went to sea. She was an old sailing frigate, armed with 64-pounder truck guns, but we could parallel our guns although the method used was somewhat primitive. When this description of firing was to be used, the captain of the gun stretched a line (called the convergence line) from the centre of the port to the rear, and held it vertically over a mark on the deck. Then the men, with handspikes and tackles, hove the gun round until the sights were parallel to the line. In this way all the guns of the broadside were placed fairly correctly for direction, and the allowance for convergence was introduced. For elevation a wooden batten was used, marked in degrees with a good open reading ; the guns were laid by it and fired simultaneously by word of command.
简单来说，方位角设定：炮长从船舷的炮门中央牵一根绳子，垂直通过甲板上的一个刻度标记，然后炮手用撬杠和拉绳移动炮车使炮管对准这根绳子。
高低角是通过一个木楔来设置
号炮一响，万炮齐发
与无畏舰的指挥仪不同的是，这个汇聚点是事先调校固定死的，指挥仪不能实时去调整每门炮的方位角瞄准敌舰，而是需要不断操控调整航向保持敌舰在瞄准具内，通过舰体来瞄准，比较类似战斗机。所以随着敌舰机动性的提高，这东西作为帆船时代的遗物，基本就是聋子耳朵——摆设了。

望我熊族反乱拨正{:17:} 陈悦先生写的估计是为了说明可以一同开火，不过那个年代实战中估计用不上
