Towards Real-Time Computational-Fluid-Dynamics-Based Aeroelastic Computations Using a Database of Reduced-Order Information

摘要

This paper describes a computational-fluid-dynamics-based computational methodology for fast on-demandnaeroelastic predictions of the behavior of a full aircraft configuration at variable flight conditions and demonstratesnits feasibility. Themethodology relies on the offline precomputation of a database of reduced-order bases andmodelsnassociated with a discrete set of flight parameters, and its training for an interpolation method suitable for reduced-norder information. The potential of this near-real-time computationalmethodology for assisting flutter flight testingnis highlighted with the aeroelastic identification of an F-16 configuration in the subsonic, transonic, and supersonicnregimes.
