为改善潜艇泵喷推进器转子盘面流场的不均匀性，降低潜艇噪声，提高潜艇的隐身性能。设计一种取消尾舵的潜艇矢量泵喷推进器，基于RANS方法对潜艇矢量泵喷推进器水动力性能进行数值计算，对潜艇尾流场特性、矢量泵喷推进器的推进性能和操纵性能进行研究，并与常规泵喷推进器作比较。计算结果显示，潜艇采用矢量泵喷推进器可取消尾舵的布置，降低转子盘面流场不均匀性，整体总阻力降低，推进器收到功率减小，推进效率提高19.9%；在0°~30°操舵舵角范围内，矢量推进器最大偏转力矩大于常规泵喷推进器+尾舵的偏转力矩。在相同的操舵角度下，矢量泵喷推进器偏转力矩大于常规泵喷推进器，说明潜艇安装矢量泵喷推进器可满足航行机动性的要求。这项研究为降低潜艇桨盘面不均匀性，提高潜艇声隐性能提供了新的途径。
In order to ameliorate inhomogeneity of flow field on rotor disk, reduce the noise of submarine and improve the stealth performance of submarine. This work mainly designed a submarine vector pump-jet propulsion without tail rudders, nd the hydrodynamic performance of the submarine vector pump-jet propulsion has been numerically calculated based RANS, the characteristics of the submarine wake field, the propulsion performance, and the maneuverability of the vector pump-jet propulsion have been studied, than compared with the conventional pump-jet propulsion. The calculation results show that the use of vector pump-jet propulsion on submarines without tail rudders can reduce the inhomogeneity of flow field on rotor disk, overall total drag, thruster power received, and improve propulsion efficiency. In the range of 0°~30° steering rudder angle, the maximum deflection moment of the vector thruster is larger than that of the conventional pump-jet thruster + tail rudder. Under the same steering angle, the deflection moment of the vector pump-jet propulsion is larger than that of the conventional pump-jet propulsion, indicating that the submarine-mounted vector-pump-jet propulsion can meet the requirements of navigation maneuverability. This research provides a new way to reduce the non-uniformity of submarine propeller disk and improve the acoustic concealment performance of submarines.
