十字舵与X舵潜艇的水动力性能数值比较

现代潜艇尾操纵面建筑形式主要选择十字舵与X舵,这2种形式的舵各有其优缺点.在以往关于这2种舵形潜艇操纵性水动力的研究中,有研究者通过编制潜艇六自由度运动仿真程序,对十字舵与X舵在水平面和垂直面的水动力性能进行了综合比较,得出X舵的水动力性能优于十字舵.本文以十字舵和X舵Suboff为研究对象,通过CFD数值方法模拟了潜艇直航运动和垂直面变攻角运动这2种具有典型代表意义的运动情况,分别计算了2种舵形潜艇的操纵性水动力,通过分析计算结果,定量地比较了在舵面积相等的情况下十字舵与X舵潜艇的水动力性能,得出与编程仿真相同的结论:X舵的水动力性能优于十字舵.

Numerical comparison on hydrodynamic performance of cross rudder and X rudder submarine

Now submarine main cross rudder and tail control surfaces architectural form X rudder, the rudder have their advantages and disadvantages of these two forms. In the past about the two kinds of steering maneuverability hydrodynamic studies, researchers by submarine six degrees of freedom movement simulation program, the cross rudder and X rudder in the horizontal plane and vertical plane of hydrodynamic performance makes a comprehensive comparison, concludes that X rud-der hydrodynamic is better than cross rudder. Based on cross rudder and X rudder Suboff research object, through CFD nu-merical method to simulate the submarine direct movement and vertical angle of attack motion trajectory of these two kinds of typical significance, and separately calculated the two steering maneuverability hydrodynamic shape submarines, through analysis of calculation results, quantitatively compared under the condition of the rudder area equal cross rudder and the hy-drodynamic performance of X rudder submarine, and programing simulation the same conclusion: the hydrodynamic per-formance of X rudder is better than that of cross rudder.
