一、引言鱼雷是一种能在水中自动推进、导引,用以攻击水面或水下目标的水中兵器。鱼雷速度则是鱼雷的一项重要战术技术指标,速度快,可以扩大使用范围并提高命中率。要想提高鱼雷速度首先遇到的问题是鱼雷在水中高速前进时所受到的巨大的流体阻力。由于水与空气在物理性能上有很大差别,如水的密度比空气大得多,在海平面上水的密度为空气的835倍。因此以同样速度航行时,在水中遇到的阻力将为空气中(海平面)的835倍。若与高空中
I. INTRODUCTION Torpedo is an underwater weapon that can automatically propel, guide and attack the water surface or underwater. Torpedo speed is an important tactical torpedo technical indicators, fast, you can expand the scope of use and increase the hit rate. The first problem encountered to speed up the torpedo was the huge fluid resistance that the torpedo was subjected to at high speeds in the water. Since water and air vary widely in physical properties, such as water, which is much denser than air, the density of water at sea level is 835 times that of air. Therefore, when navigating at the same speed, the resistance encountered in the water will be 835 times that of the air (sea level). If with high altitude
