Abstract
In this chapter, two new airfoils with thickness to chord ratios of 30 and 36 % are presented, which were designed with an objective of good aerodynamic and structural features. Airfoil design is based on a direct method using shape perturbation function. The optimization algorithm is coupled with the viscous/inviscid flow solver XFOIL.
Wind tunnel tests for both airfoils were performed in the LM Wind Power low speed wind tunnel at Reynolds numbers of 1.5–6 million and various surface conditions. The results from the experiment confirm that the optimization algorithm is suited for airfoil design and the designed airfoils have top performance.
