基于欧拉方程的机翼设计方法及应用

Wing design method and application based on Euler equations

摘要: 以Takanashi提出的三维机翼设计理论为基础,研究与发展了一个基于欧拉方程和“正-反迭代、余量修正原理”的机翼设计方法。用改进的无限插值方法生成绕机翼的O-O贴体网格,采用三维欧拉方程作为流动分析计算的基本方程,该设计方法已用于某无人机机翼和一个超临界机翼设计，设计结果达到了预期的目标。

Abstract: In this thesis, Based on three dimensional wing inverse designtheory proposed by Takanashi, a wing inverse design method based on Euler equation and “direct-inverse iteration，residual-correction “concept is presented. The O-O mesh around wing is generated
