Abstract
A correlation approach for the identification of a Hammerstein model of unsteady aerodynamics using CFD data is presented. The main idea is to use correlation functions of the input-output processes as data for the identification problem. It is shown in a numerical example of the AGARD 445.6 wing that the proposed method can more accurately approximate the linear aerodynamic response, which is needed for a first-order prediction of wing flutter boundaries.
