摘　　要：为了优化设计适用于深海潜水器姿态调整的新型双转子对转螺旋桨,在经典的CRP4对转桨基础上,用CFD方法改变对转桨的桨型组合,得到较优的桨参数。为了提高对转桨的功率裕度,提出了一种新型CRP-Kappel对转桨,完成了系柱状态下系列对转桨的试验,得到的螺旋桨组合在电机功率低于3 kW时推力达到800 N。CRP-Kappel对转桨的创新点在于将具有端板效应的非常规Kappel系列桨型应用到传统的对转桨设计中。在系柱状态和低进流速度下它比常规桨型性能更优异。完成了不同转速下的系柱试验和仿真计算,两者最大偏差在5%以内。In this paper,a new type of counter-rotating propeller for adjusting attitude of deep-sea submersible is designed.In order to achieve engineering indicators,with the classical CRP4 counter-rotating propeller taken as the prototype,a new type of contra-rotating propeller CRP-Kappel is proposed,and a series of experiments in bollard state is completed.This new CRP-Kappel meets the target of reaching thrust 800 N within 3 kW of motor power.Main innovation of this study is applying unconventional propeller Kappel series with end-plate effect to the counter-rotating propellers.Results of the CFD simulation show that the CRP-Kappel at low advance velocity is better than conventional counter-rotating propeller CRP4,and results of the experiment and simulation are in good agreement with the error in 5%.The propeller with strong end-plate effect has better performance than convention counter-rotating propeller in terms of thrust,torque and power under bollard state and low advance ratio,which can be used as the configuration design of a special propeller for deep-sea submersibles with high hydrodynamic performance,low speed and heavy load.
