Keywords: multi-point, inverse, design, natural laminar, airfoil

A multi-point inverse design approach of NLF airfoils with a substantial amount of NLF based on target pressure distributions designed by N-factor design method is developed. Xfoil is used to calculate flow field. Optimization method based on Response Surface Methodology is used to calculate target airfoil.
