摘　　要：作为叶片设计的基本组成单元,可逆翼型的选取对整机性能的影响起着重要的作用。以性能较好的R18可逆翼型作为初始翼型,通过翼型优化方法得到一款优化翼型。利用Numeca软件对R18翼型构建的叶片进行气动性能计算并与标准风机试验台的数据进行比对,验证该数值方法的可靠性。在此基础上采用两种翼型构建两种叶片模型并用Numeca软件计算气动性能,以此对翼型优化的设计效果作出评价。研究结果表明:在设计攻角范围内,优化翼型的升阻力特性均高于R18翼型;且在设计工况范围内,优化翼型设计出的风机全压提升5.43%,效率提升0.905%。表明该翼型优化设计方法确能提高设计出的可逆地铁风机气动性能。As a fundamental component of the blade,the reversible airfoil plays an important role in the overall performance of the fan.Using the R18 reversible airfoil with good performance as the initial airfoil,an optimized airfoil is obtained through the airfoil optimization method.Numeca software is used to calculate the aerodynamic performance of the blades constructed with R18 airfoil,and the reliability of this numerical method is verified by comparing it with the data from a standard fan test bench.Then,two blade models are constructed using two types of airfoils and their aerodynamic performance is calculated by using Numeca software to evaluate the design effectiveness of optimized airfoil.The research results indicate that within the designed range of the angle of attack,the lift and drag characteristics of the optimized airfoil are higher than the R18 airfoil;under the designed operation conditions,the optimized airfoil has increased the total pressure of the fan by 5.43%and the efficiency by 0.905%.In conclusion,the airfoil optimization method can indeed improve the aerodynamic performance of the designed reversible subway fan.
