为降低泵喷推进器的横滚扭矩，采用正交模拟试验的方法对后置定子泵喷推进器进行分析，通过计算流体力学（CFD）对正交试验的不同组合后置定子泵喷推进器进行预报。以效率和扭矩系数为评价指标，分析定子叶片数量、定子安装角度、定转子安装距离、定子弦长对水动力性能的影响程度，并得出最优模型参数。最优模型相对原始模型横滚扭矩降低了76%，效率提升了4%，优化模型的尾部流场稳定性优于原始模型。后置定子的安装角度对平衡泵喷推进器的扭矩，提升推进器的效率具有重要作用。
In order to reduce the roll torque of the pump-jet propulsor, the orthogonal simulation test was used to analyze the rear-stator pump-jets, and the different combinations of the rear-stator pump-jets were predicted by computational fluid dynamics (CFD). Taking efficiency and torque coefficient as evaluation indexes, the influences of stator blade number, stator installation angle, fixed rotor installation distance and fixed chord length on hydrodynamic performance were analyzed, and the optimal model parameters were obtained. Compared with the original model, the roll torque of the optimal model is reduced by 76%, and the efficiency is improved by 4%. The stability of the tail flow field of the optimized model is better than that of the original model. The installation angle of the rear stator plays an important role in balancing the torque and improving the efficiency of the pump injection propeller.
