Abstract : This report describes a study performed to evaluate a 3D, full potential, computational method developed at the Lockheed-Georgia. This computational method was used to compute both steady and unsteady compressible flows about an F-5 fighter wing model. Comparisons are made between computed steady and unsteady aerodynamic data and available experimental data for the F-5 planform. Correlations are presented for steady, unsteady and quasi-steady surface pressure distributions and integrated loads coefficients. Originator-assigned keywords include: Computational fluid dynamics, Unsteady aerodynamics, and Transonic flow.
