第一次世界大战以来,各国海军主要水面舰艇的最高航速,一直保持在30～40节之间,没有什么新的突破。但这一期间飞机的航速已从时速150公里左右,提高到现在的超音速了。在这科学技术突飞猛进的时代,常规水面舰艇的航速为什么提不高呢?以美国7800吨的导弹驱逐舰斯普鲁恩斯号的航速来说,也仅在30节左右。因此引起了人们的一些非难。他们总认为军事舰艇应该是越快越好,而不去考虑其是否可能和是否需要。大家知道主要影响着常规水面舰艇航速的阻力有两种:摩擦阻力和兴波阻力。对于一艘快速常规水面舰艇,后者是更为主要的。摩擦阻力与船体水下面积成正比;
Since the First World War, the maximum navigational speed of major naval vessels of various countries and naval vessels has remained at between 30 and 40 knots, with no new breakthroughs. However, the speed of the aircraft during this period has increased from about 150 kilometers per hour to the current supersonic speed. In this era of rapid scientific and technological advances, the conventional surface ships why not mention the speed it? The U.S. 7,800-ton missile destroyer Spruance number of speed, it is only 30 or so. Therefore caused some of the people’s censure. They always think that military ships should be as fast as possible, regardless of whether it is possible and needed or not. We all know that there are mainly two kinds of resistance that affect the normal surface ship speed: friction resistance and wave resistance. The latter is more important for a fast conventional surface ship. Frictional resistance and the hull is proportional to the underwater area;
