N2 - Proper-orthogonal-decomposition (POD) methods have recently been developed for the design of airframe components. In this paper, two POD-based approaches have been studied: the Gappy POD reconstruction procedure (Ref. 6) and the gradient approach (Ref. 7). Both methods do not require a projection onto the CFD governing equations, but are, instead, a collection of flow snapshots that covers the parameter ranges of interest. Their performance on the inverse design of various airfoil shapes such as Korn, NACA63212, HQ2010, and GOE117 airfoils has been compared and evaluated. Our studies show that, while both methods are efficient and accurate once appropriate flow snapshots have been collected, the gradient-based method is generally more accurate.
