Abstract

The proposed approach in this paper aims to bring the accuracy of CFD to quick linear aeroelastic simulations for structural sizing. This is achieved by deriving reduced-order models (ROM) of the aircraft movables, gust loads and manoeuvres loads from rigid CFD analysis and to use these as substitutes for the loads in the aeroelastic simulation. The corrected loads can then be incorporated into the wing-box sizing process which relies on a gradient-based optimizer that will eventually determine the optimal stiffness and thickness distribution of the wing structure.
