水纳尔逊:奶油炮?

最近在翻战列舰论坛时,偶然发现了一段话:
owaii是dalao
owaii:
不要迷信Navweaps上面根据美国经验式算出来的英国炮穿深……英国人如果认真一点改进MkI的身管和膛线,使其达到823的设计初速,那么MkI的威力还能上一个台阶。

狮级的马克2,3,4动能301兆焦 和马克6差不多····1080重弹747就真得320了····这穿深也不算弱····这炮要是德国给力点就真能列装····威力比40.6cmC34弱些···
给乔5设计的15寸炮 879重弹初速836!!逆天了····动能307兆焦比16寸都狠····
就是穿深数据特别水····还没38cm C34高····
owaii:
15寸45口径那个836的初速,要么是写错了,要么是强装药数据。因为它与标准装药下2510fps的数据对不上。
至于穿深,那上面的英国炮穿深几乎全是常装药下的旧炮数据,而且是按美国经验式算的,普遍偏低。
网友:
MKI 15寸都有不小的上强装药的潜力,MKI上了强装药,威力可以达到甚至超过SKC/34。这种新炮肯定有,如果上了强装药,威力起码可以达到Model 1935的水平。(毕竟连MKI的药室容积都比Model 1934大,而众所周知,Model 1934威力比Model 1935更大)
我去其他地方看过很多帖子,不少人都认为英国舰炮有上强装药的潜力,但是那仅针对MKVII 14寸和MKI 15寸,几乎没人说老纳的MKI 16寸还有增加威力的潜力,不知为何。
owaii:
因为16寸本来设计初速是823,因为试射的时候炮管烧蚀严重,甚至有膛线剥离的倾向,才把初速降下来的。这要是强装药得是什么效果?
"British Battleships of World War Two" credits these guns as being originally designed with a muzzle velocity of 2,700 fps (823 mps) and a maximum range of 41,983 yards (38,389 m). The very first test firings of these guns found that they had a serious wear problem, with a barrel life of only 180 rounds. It was also found that there was a considerable loss of accuracy during continuous firing, as there was a tendency for the projectiles to strip the rifling out of the guns ". . . due to the hammering action of the short bodied, long headed projectile on its way down the bore . . ." As a result, the rifling in the liners was changed (known as Mark II rifling) for newer guns, the powder charge and chamber size were reduced to the figures shown in the tables above and the diameter of the projectile driving band was increased. Even with these changes, the barrel life and accuracy still compared poorly with the previous 15"/42 (38.1 cm) Mark I.
网友:
不得不说 这炮的药室容积超其他16寸炮至少100dm3 按理说绝对有强装药潜力····至少有考虑到强装药的可能性
有可能不是炮的原因,是老衲设计的问题,正常装药齐射都那个程度,更何况强装药 全主炮前置战舰的齐射会对上层建筑损伤很大 如果说真正搞强装药这炮初速上840应该不难····
神教:
看这话意思,膛线的问题主要是炮弹的形状造成的,脑袋很长,身体很短,而且问题产生于将炮弹推进弹膛的阶段,而不是发射阶段
所以,纳尔逊改进炮弹,改善内膛工艺,可以尝试达到Mk-6的水平?也就是说,我们看到的纳尔逊,实际上是减装药的模式?
