Abstract
In this article, we propose an innovation method of airfoil shape optimization, on the premise of ensuring the fitting accuracy; try to improve the smoothness of the airfoil. Non Uniform Rational B-Spline and quadratic penalty function are employed to parametric modelling and smoothness optimization. The monotone curvature variation is used to design smooth curves and least squares method ensuring high fitting accuracy. This program has been tested for a standard NACA 2415 and S825 airfoil and optimized to improve its smoothness. The results of optimization examples show that this method has high efficiency and precision.
