Inverse design of a thick supercritical airfoil

In this paper, a study on designing a thick supercritical airfoil by utiliz ing Takanashi's inverse design method is discussed. One of the problems to design a thick supercritical airfoil by Takanashi's method is that an oscil lation of the geometry may occur during the iteration process. To reduce th e oscillation, an airfoil parameterization method is utilized as the smooth ing procedure. A guideline to determine the target pressure distribution to realize the thick airfoil is also discussed.
