| 摘 要： | 为了拓展Leishman-Beddoes(L-B)动态失速模型的应用范围,以适应特定翼型的动态失速分析,在详细分析L-B动态失速模型特点的基础上,提出一种模型参数的识别方法。以SC-1095翼型为例,采用其静态升阻特性数据,对L-B动态失速模型中的参数进行了识别,并据此对该翼型的动态失速升阻特性进行了数值计算,计算结果与试验值吻合良好。

| Abstract: | On the basis of the characteristics of Leishman-Beddoes (L-B) dynamic stall model, the method of parametersidentification was put forward in order to expand the application range of L-B dynamic stall model and adapt to dynamicstall analysis of specific airfoil. The dynamic stall lift and drag were calculated with the parameters identified from the stat.ic stall lift and drag curves of SC-1095, the results agreed well with the experimental value. |
