N2 - A flapped, slotted, natural-laminar-flow airfoil was recently designed and tested that has potential use for low-Mach and low-to-mid Reynolds numbers applications. To evaluate the potential performance benefits of this airfoil, it is applied to the wing of an 18-meter sailplane and compared with an analysis of the Schmepp-Hirth Ventus-3 wing. As part of the preparation for the analysis, airfoil polars are compared with wind tunnel data to validate the methods. The wing comparisons are then made, both with visualizations and performance results. Lastly, conclusions regarding the gains with the SNLF airfoil are discussed.
