在翼型优化前首先要对翼型进行参数化处理,我们知道一般翼型都由一系列的点表示,这个方法的好处是足够精确,只要支持样条线的软件都可以精确将翼型形状复现出来,但是缺点在于参数太多,直接将点集作为优化的参数一方面对计算资源的消耗极大,一方面容易产生不光滑的翼型或者说无意义的翼型导致收敛速度减慢和计算资源的浪费。CST...
The invention discloses an improved CST (Class Function/Shape Function Transformation) airfoil profile parametric method, which comprises the following steps: firstly, preprocessing the outline of an airfoil profile; then, calculating the Ratio(x) curve of the airfoil profile; determining the node and...
