| Abstract: | A finite difference scheme for solving second-order non-linear partial differentia! equation is presented and a numerical calculation method for solving the two-dimensional transonic small perturbation equation is also given. Transonic surface pressure distribution over two-dimensional symmetric airfoils at zero attack angle. The results of both calcuiation and expriment show a good agreement with eaqch others. |
