摘要
潜艇前置导叶螺旋桨系统是中国船舶科学研究中心最近开发出的一种潜艇增效降噪的新装置。文中描述了它的组成和布局形式，阐述了其增效降噪原理，并对试验研究和开发的情况进行了介绍。
Submarine Guide Vane Propeller is a new device developed by CSSRC for improving poweringPerformance and reducing noisiness of submarine. It is composed of propeller and guide vanes,the latter areinstalled at an appropriate position between stern appendages and propeller.Because the guide vanes in front of propeller can provide a pre-swirl inflow to downstream propeller andregulate radial load distribution on propeller blades, so that the energy losses in propeller wake and the unsteady forces and cavitation on blades can be reduced.Development and model experiment results of Submarine Guide Vane Propeller are presented in thispaper. It is shown that the new device can save energy by 5-10 percent and reduce noise by 2-3 dB.
