Abstract

This paper presents a new methodology to increase the accuracy of gust loads analysis, evaluated by means of traditional potential flow models. Linearised frequency domain aerodynamic loads have been used to estimate the correction factors necessary to update the Aerodynamic Interference Coefficients matrices for gust and mode shapes deformation. The results, obtained using a corrected doublet-lattice method, are presented and compared to the fully coupled CFD/FEM results computed with a Fluid Structure Interaction interface. The application of this technique to a wing model, representative of a general single aisle civil aircraft, has shown an excellent agreement to the fully coupled results, both for rigid and flexible aerodynamic loads in the transonic regime.
