摘　　要：为分析一体化推进器的推进及空泡性能,基于多特性平衡设计思想,采用势流理论面元法建立了一体化推进器设计方法。对不同舵球直径时的桨舵推进系统水动力性能进行了仿真分析,确定了舵球直径对推进性能的影响规律。以舵阻力及压力系数最小为设计目标,采用速度场的迭代计算考虑桨舵之间的相互干扰,开展了舵不同展向剖面的扭曲设计。模型试验结果表明:建立的一体化推进器多特性平衡设计方法是有效的,桨舵一体化推进器可减小舵的阻力,增加螺旋桨的推力,提高桨舵推进系统效率,并显著改善舵的空泡性能。To analyze the propulsion and cavitation performance of an integrative propulsor,we developed a multicharacteristic balanced design method for the integrative propulsor using the surface panel method based on potential flow theory. We calculated the performance of a propeller-rudder system with different rudder-ball diameters,and obtained the law of influence of these diameters on the propulsion performance. Then,we designed rudder sections with different span directions to minimize resistance and pressure. We determined the interaction between the propeller and rudder by iteratively calculating the induced velocity. Model test results indicate the effectiveness of the balanced design method for the integrative propulsor,which can reduce rudder resistance and increase propeller thrust. Therefore,it can increase the efficiency of the propeller-rudder system and significantly improve the cavitation performance of the rudder.
