摘　　要：为减小螺旋桨尾流能量耗散,提高桨舵系统的推进效率,开展桨舵组合式推进器设计研究。首先,基于适伴流设计思想结合面元法编制最大阻力减额的扭曲舵设计程序,获得桨后舵不同展向位置的扭曲角度,并通过与一前端削平的舵球及桨毂光顺连接形成桨舵组合式推进器的设计方案。然后,采用数值仿真分析获得均匀流场中桨舵组合式推进器的水动力性能、压力分布与流场特性等细节,初步验证设计方案的合理性。最后,开展船后桨舵组合式推进器的水动力性能试验,获得不同航速下螺旋桨和舵的水动力性能。试验结果表明,桨舵组合式推进器较原型桨舵推进器的效率在全航速段均有一定程度的提升,在设计工况点提升值达2.7%,证明设计方法正确,设计方案合理可行。In order to reduce the wake dissipation and improve the efficiency of the propulsion system,aresearch on the design of assembled propeller is carried out. The theory of optimum design of wake com-bined with max resistance reduction is first programmed to obtain the twist angle of the rudder at differentsections. The design scheme of the twist rudder is then obtained with a flap end rudder ball assembled be-fore the twist rudder,which smoothly connects with the propeller hub. Simulation results of hydrodynamicperformance,pressure distribution,and wake details are analyzed,which successfully validates the de-signed scheme. The experiment of propulsion hydrodynamic performance behind the ship is also carried outto obtain the efficiency improvement of the assembled propeller. The results show that the assembled pro-peller improves propulsion efficiency under all speed conditions,where the value at the designed point is2.7%,which further validates the correctness of the design method and the rationality of the designedscheme.
