Brief Abstract: A new methodology is presented for adapting parameterized reduced-order models stored in databases using suitable interpolation schemes on matrix manifolds. The proposed methodology is illustrated with its application to real-time computational aeroelastic analyses of full aircraft configurations: methods are developed for the interpolation of CFD-based fluid and Finite Element-based structural reduced-order models. The use of databases of reduced-order models is shown to considerably reduce the computational cost of the analysis, enabling on-line flutter predictions.
