摘要
本文基于Bezier曲线,采用MATLAB软件,对翼型的参数化展开研究。同时,针对翼型的前缘、尾缘在参数化过程中出现的尖点问题提出了平行点处理方法,以提高参数化精度,准确地表达翼型的几何特征。本文对几种翼型在不同阶次下的参数化曲线结果进行了误差分析,通过与原始数据的对比,进一步证明了本文提出的翼型参数化方法具有精度高,实用性强的特点。
An approach based on Bezier-curve is proposed for the parameterizing of various types of airfoils by using of MATLAB software. Specially, a simple and convenient method is discussed, which can be adopted to smooth the leading and the trailing edges. Comparing with some traditional parametrized curve results in different orders, the method described in this paper is proved to be correct and effective in the process of parametrization.
