鱼雷锚的方向稳定性研究

摘要

在鱼雷锚被释放到水中后的安装过程中，锚的方向稳定性是其贯穿海床性能的重要因素。本文中，用CFD的方法模拟锚的下降过程，并利用具体的参数研究分析其对方向稳定性的影响。研究结果表明，一些参数，如重量，重心，和尾翼的展弦比和锚体的长宽比对方向稳定性有着显著的影响。%After a torpedo anchor is released into water during its installation, the directional stability of the anchor will be an important factor for its penetration performance. In this paper, a CFD method is used to simulate the falling behavior of the anchor, and detailed parametric studies are conducted to analyze the effects of various parameters in the directional stability. The results show that the parameters such as weight, gravity center, aspect ratio of fin and length-width ratio of the anchor have significant influence on the directional stability.
