气幕喷气环阻力性能实验研究

Experiment Research on the Resistance Performance of Bubble Screen Air Emitter Belt

气幕系统是目前降低舰艇水下辐射噪声的一种有效措施.通过在水筒中进行的气幕喷气环阻力性能试验,就喷气环的外形尺寸、截面形状和喷气流量对阻力的影响进行了研究,得到了所研究气幕喷气环的阻力数据.

It is a useful way to use bubble-screen to reduce the noise radiation of naval vessel underwater, though the resistance of a ship installed the bubble-screen air emitter belt will be larger. Through the experiment carried out in a water pot under conditions of different shape dimension, section figure of air emitter belt and the quantity of air, the research on how these conditions effect the resistance is done, and the actual resistance values of the bubble screen air emitter belt are also got.
