摘　　要：为了提高旋翼螺旋桨的综合气动性能,基于叶素-动量组合理论并耦合了计算流体力学(Computational fluid dynamics,CFD)方法,设计了一款旋翼螺旋桨,进行了螺旋桨巡航及悬停状态的气动特性计算及流场仿真,计算结果与风洞试验数据进行了对比分析。研究结果表明,在进行网格无关性研究基础上,数值计算与风洞试验的误差较小,设计点平均计算误差为3.0%左右,所采用的CFD计算方法具有较高准确性和可信度。设计的旋翼螺旋桨巡航效率高于80%,悬停效率高于70%,具备了较好的巡航及悬停的综合气动性能。In order to improve the aerodynamic performance of the rotor propeller,aerodynamic design of a rotor propeller based on the blade element momentum theory(BEMT)and computational fluid dynamic meth⁃od was implemented.The aerodynamic performance and flow field of the rotor propeller in the cruise and hover status was calculated using CFD method,and numerical results were compared with wind tunnel test data.The research conclusion show that the numerical results are in good agreement with the experimental data after con⁃sidering the grid independence study.The average calculation error of design point is about 3.0%,and the CFD method has high accuracy and reliability for practical engineering application.The designed rotor propel⁃ler has good comprehensive aerodynamic performance with higher than 80%cruise efficiency and 70%hover ef⁃ficiency.
