| 摘 要： | 利用气流提高鱼雷螺旋桨叶片处的压力，减少螺旋桨的空泡，从而降低鱼雷辐射噪声，以及利用人工气幕屏蔽螺旋桨噪声，可以大大减小在鱼雷基阵处的自噪声。实验研究表明，在鱼雷自导工作的频率范围，可降低自噪声约１０ｄＢ以上。

| Abstract: | There are two methods to cut down the self noise of torpedo transducer array:reduce air-bubbles induced by propeller so as to decrease the radiated noise of torpedo by means of using air flow to increase the pressure at the place of torpedo propeller blade and screen the propeller noise by use of man-made air-bubble curtain. The experimental results show that more than 10 dB of self noise can be decreased in the frequency band which the torpedo homing head works at. |
