Rapid Design of Subcritical Airfoils

In this paper, we present a fast, ecient and accurate algorithm for rapid design of sub-critical inviscid airfoils. The compressible potential ow equations in the hodograph plane are cast into a nonlinear integral equation which is solved using an iterative method in this approach. Some numerical results are presented. 1. Introduction. We consider the problem of inverse design of airfoils in subcritical compressible ows. This problem has a long history, especially, on the numerical approaches to solving this problem ([3]-[6]). With the advent of high speed computers, considerable eort has been directed towards ecient design of airfoils because it has the potential of signicantl
