那Friedman这个“In any case, it appears that the construction of the new battleships was too urgent to allow for caisson tests until all four were well under construction. Then, in 1939, C&R discovered that its new system was considerably less effective than earlier ones. The best it could do was to fill the outboard spaces, which in earlier systems had been left empty, on the theory that what really counted in underwater protection was an inboard void and the deepest possible liquid layer. Note that these developments occurred not only after four ships were under construction but also after the next design, the Iowa, was substantially complete.”怎么说呢
从这个实验的时间(1938,明显早于印第安纳开工)的确有可能是设计初期时(这个主装还是内倾的,应该比较早了)已经确定了外侧载液布局然后再做的实验验证,这样的话“earlier systems”可以说是指北卡那样的设计?但最后一句又显得是后面才提出外侧液体的理论,弗里德曼也弄错了? |
