摘　　要：潜艇做水平面转向运动时,指挥室围壳处于有漂角的斜流之中,受主艇体与围壳干扰后的流场作用于艇上产生的水动力与力矩,使潜艇常伴随出现另外2个坐标平面上的耦合运动,即横倾、纵倾和潜浮运动,而围壳的高度与外形特征对耦合运动的幅度有直接的影响.文中对一近似常规潜艇模型的指挥室围壳进行优化,得到了低矮化、流线型化的3种围壳模型,采用CFD方法计算比较了这几种模型在漂角β(0,°10°)内与耦合运动有关的水动力性能及表面压力分布,计算表明低矮化、后缘流线型化的围壳能有效降低艇体水平转向时的横倾与纵倾幅度,为潜艇指挥室围壳的外形优化设计提供参考.When a submarine executes a horizontal turning,the sail experiences a crossflow velocity component.The forces induced by the composite flow-field act on submarine and lead to coupled motions in another two coordinate planes,such as roll,pitch,and depth-changed motions.The height and hull of the sail are extremely important to the amplitude of coupled motions.By reducing sail height of conventional submarine and streamlining it,three sail models were obtained.The pressure distributions around the hull and the hydrodynamic forces related with roll and pitch motions were computed with varying drift angles β（0°,10°）.It indicates that shorted,streamlined sails can reduce the amplitude of roll and pitch motion during a horizontal turning.The conclusion can give some reference to submarine sail′s design.
