摘要
引起潜艇暴露的重要因素是它产生的声场,螺旋桨的空化噪声是潜艇辐射噪声高频部分的主要成分。航速和下潜深度对潜艇螺旋桨空化噪声影响显著。从螺旋桨升力面理论出发,建立了一种计算螺旋桨空化临界速度和空化临界深度的方法,并对潜艇螺旋桨空化临界特性进行了仿真分析。计算结果与测试结果的比较验证了该算法的有效性。
The important factor that causes the exposure of a submarine is the sound field produced by the submarine itself, the main part of the high frequency noise eradiated by a submarine is cavitating noise of the propeller. The speed and depth of submarine have notable impact on propeller-eavitating noise. Based on the lifmg-surface theory, a method of calculating propeller-cavitating critical speed and cavitating critical depth was established, and the cavitating critical characteristics of the propeller was analyzed The comparison of the conclusions drawn by calculating and testing proves that the method mentioned above is effective.
