Data Fusion of CFD Solutions and Experimental Aerodynamic Data

Abstract

During the development of an aircraft, comprehensive aerodynamic datasets are required for performance, loads or handling qualities simulations. The required data can be obtained, e. g., by Computational Fluid Dynamics (CFD) or wind tunnel testing. To combine datasets of different fidelity or resolution a Gappy-POD method based on Proper Orthogonal Decomposition (POD) is exploited. In a second step different regularization schemes for the linear least squares problem are analyzed. The pressure distribution of the flap of a transport aircraft wing is used as a test case. Results for the ordinary Gappy-POD solution as well as for two regularization schemes are presented.
