| 摘 要： | 介绍潜艇水压式计程仪的使用原理和方法,分别对SUBOFF潜艇在水面和水下两种航行状态进行了三维粘性数值模拟,获得潜艇计程仪相关部位的流场信息,利用这些信息仿效计程仪的测速过程,得出潜艇水压式计程仪"水上标定,水下用"将会使潜艇测速结果低于实际航速的结论.

| Abstract: | The theory and means of pressure log used in the submarine are introduced.Numerical calculation of the 3D viscous flow over a main hull of SUBOFF is made,and flow field data relative to submarine log are got by calculation.The result shows that the test speed of the submarine would be lower than the actual speed of the submarine if the pressure log is corrected during sail-up and used under water. |

| Keywords: | submarine pressure log speed trial error numerical calculation |
