【摘要】 本文给出了求解多段翼型位流准确解的一种方法。采用求解拉普拉斯方程把多段翼型绕流区域变换成一个有限矩形域,然后把此矩形域变换成多个圆,从而通过求绕多个圆的准确位流解来求得绕多段翼型位流的准确解。本文提供的方法能广泛应用到任意外形的多段翼型位流计算。采用这种方法计算所得的位流压力分布与用其它方法求得的压力分布非常吻合。更多还原

【Abstract】 A new method is presented to calculate the exact analytic solution of potential flow about multi - element airfoils. The potential flow about multi -circles is calculated by the method of images, and multi-circles are transformed to multi-element airfoils by calculating the numerical solution of a partial differential system. This method can be applied to airfoils of arbitrary shape. Airfoils pressure distribution has been computed by this method and is in good agreement with independent results.更多还原
