Many previous studies focused on developing optimum airfoils for steady flight conditions. However, with minimal extensions airfoils could be designed to perform better at the take-off conditions which would result in the efficient take-offs at shorter runways. An inverse design technique called the Modified Garabedian McFadden (MGM) technique was applied to NACA 0012 airfoil which resulted in an airfoil with drag bucket at the normal flight operation conditions. A newly developed optimization technique was applied to the three-element take-off configuration and a configuration that produced higher lift was obtained. Future work could be conducted on extending these design techniques for various airfoil configurations.
