摘要
对三维机翼的优化设计方法进行了研究。采用基于梯度信息的优化搜索方法,以及参数化方法,三维欧拉方程和离散共轭方法,形成了一套对三维机翼的优化设计方法。根据该方法,选取升阻比为目标函数,对机翼进行了优化设计,并对这些结果进行分析。通过设计说明了运用该方法对三维机翼进行优化设计是切实可行的,并且总结了在实际工程应用中如何更加有效地使用该套设计方法。
An efficient gradient-based optimal method is presented for the design of wing, combined with Eular solver and optimization constraints which are enforces through a penalty formulation. The adjoint method is applied to solve the discrete-adjoint equation, leading a fast computation of accurate objective function gradient. The ratio of lift to drag is selected as the objective function. Several design examples are provided which demonstrate that this algorithm provides an effective and practical tool for the design of wing.
