摘　　要：针对传统机桨匹配设计的局限性,提出将计算流体动力学(Computational Fluid Dynamics,CFD)技术应用到机桨匹配初步设计计算中。应用Fluent软件计算螺旋桨性能参数,在一定进速系数范围内进行机桨匹配。运用CFD技术预报螺旋桨性能参数,结果表明试验值与预报值的吻合度较高,该CFD技术可应用到机桨匹配实际设计中。将CFD技术应用到机桨匹配初步设计中进行实例计算比较,结果表明该设计思路具有一定的可行性。In view of the limitation of traditional engine-propeller matching process,to perform preliminary matching between the propeller and the engine with Computational Fulid Dynamics(CFD)technology is proposed.The propeller performance parameters are calculated by Fluent software,and the engine-propeller matching is carried out within a given speed coefficient range.Tests show that the test values are in good agreement with the predicted values,and the method can be applied to the practical matching process.The method has also been used in practical design and proved to be feasible.
