论文摘要
我们逐步设计（DBM），这是一种新型设计方法，可用于创建搜索空间以优化2D机翼。大多数设计技术都会在设计空间本身上施加几何限制，有时是设计师的偏见，从而限制了创建的设计的新颖性，并且只允许局部小变化。我们表明，DBM方法论不会对设计空间施加任何此类限制，并允许从搜索空间推断，从而用一些设计参数授予真正的激进和大型搜索空间。与其他形状设计方法相比，我们应用DBM为2D机翼创建搜索空间。我们优化了这个机翼形状的设计空间，以最大程度地提高拖盘比率，$ cld_ {max} $和失速角度公差，$Δα$。使用双向目标遗传算法来优化DBM空间，发现我们创建了一个激进的翼型的帕累托前翼，这两个目标都表现出显着的特性。
We present Design-by-Morphing (DbM), a novel design methodology applicable to creating a search space for topology optimization of 2D airfoils. Most design techniques impose geometric constraints and sometimes designers' bias on the design space itself, thus restricting the novelty of the designs created, and only allowing for small local changes. We show that DbM methodology does not impose any such restrictions on the design space and allows for extrapolation from the search space, thus granting truly radical and large search space with a few design parameters. In comparison to other shape design methodologies, we apply DbM to create a search space for 2D airfoils. We optimize this airfoil shape design space for maximizing the lift-over-drag ratio, $CLD_{max}$, and stall angle tolerance, $Δα$. Using a bi-objective genetic algorithm to optimize the DbM space, it is found that we create a Pareto-front of radical airfoils exhibiting remarkable properties for both objectives.
