RESUMO

A new iterative method for solution of the inverse airfoil problem in a compressible gas flow within the framework of RANS equations has been developed. The method belongs to the class of residual correction methods. An airfoil geometry correction, decreasing the residual between the computed and desired pressure distributions, is defined by means of a correction block based upon the previously developed domestic inverse full-potential code. Several examples of inverse problem solution showing high efficiency of the method are given.
