| 在潜艇航行过程中，指挥台围壳部分的阻力在潜艇总阻力中占有较大的比重。同时，由于指挥台围壳引起的潜艇尾部伴流场的不均匀性和不稳定性，使得螺旋桨产生较高的低频离散噪声、低频宽带噪声。因此指挥台围壳对潜艇的阻力和螺旋桨噪声具有重大影响。 尽量优化围壳型线，减少围壳带来的不利影响，是潜艇设计者追求的目标。当前对指挥塔线型的设计与优化，主要是采用求解 RANS 方程的 CFD 软件的数值计算方法，对不同方案模型进行数值计算，综合比较后得到最优的围壳设计方案。本文不同于传统研究中将潜艇指挥塔看作为横剖面是椭圆形的柱体，而是利用垂向函数，研究了指挥塔剖面的弦长与半宽都随高度而变化时横剖面为翼型的指挥塔的数学线型。针对梯形指挥塔和填角弧形指挥塔，通过求解超越方程组，得到指挥塔线型。根据对SUBOFF潜艇的算例，验证了本文提出的数学线型方法的有效性。 |

| In the process of submarine voyage, podium circumference shell part of resistance in submarine occupies a large proportion in total resistance.At the same time, due to the podium shell around submarine tail with the nonuniformity of flow field and instability, makes the low-frequency discrete noise of the propeller to produce high and low frequency broadband noise.Therefore podium confining shell has a significant influence on the resistance of the submarine and the propeller noise.Optimization of confining shell mold line as far as possible, reduce the negative influence of confining shell, is the goal of the submarine designer.The current design and optimization of control tower lines, mainly using solving RANS equation numerical method of CFD software, numerical calculation of different schemes model, after the comprehensive comparison get optimal shell design.This paper will be different from the traditional research submarine control tower as an elliptic section cylinder, but USES vertical function, studies the control tower section of the chord length and a half wide and change section with height for profile control tower of linear mathematics.In view of the trapezoidal control tower control tower and fillet arc, by solving equations, linear get the control tower.According to the SUBOFF submarine case to verify the effectiveness of the proposed mathematical linear method. |
