多段翼型分析和反设计位流计算

Potential Calculation of Analysis and Inverse Design for MuItielement Airfoils

本文采用第二代低阶面元法给出了多段翼型分析和反设计位流计算方法。按照曲率变化情况划分板块可很好地提高计算效率。

In tlis paper,based on second generation low ordcr panelmethod,a computiounal method of mixed analysis and design for multiele-ment airfoils has been given. Each airfoil element is divided into analvsisregions of prescribed geometry and design regions of prescribed Dressuredistribution. Iteration between analysis and inversc geometry-pressurerelationship is employed. It Ieads to usually a good and rapid solutionconvergence that panels are generated in the light of variant curvatureconditions.
