Abstract
An iterative method for solving the inverse problem for a multielement (slotted) airfoil at high speeds in a viscous compressible flow, using RANS methods, has been developed. It is an evolution of a similar method developed earlier by the authors for low speed conditions. The method is based on the well-known principle of residual correction, according to which corrections to the current geometry are generated on the basis of the difference between the target and current pressure distribution. A brief description of the algorithm and the methods used is given. Examples for the slotted airfoil design corresponding to the target pressure distribution are given, including cases with the shock waves existence.
