This substantially reduces the computational cost necessary to de\ufb01ne the corrected Aerodynamic Interference Coef\ufb01cients matrices. The results obtained from the corrected doublet-lattice method are compared to the fully coupled CFD\/FEM solution performed using the Alpes Fluid Structure Interaction Interface. The application of this method to two test cases, representative of civil jet airliner in cruise condition, in transonic regime, is presented. The \ufb01rst test case is an Euler simulation for the FFAST right wing model, while the second presents preliminary results obtained using a viscous simulation for the NASA common research model. The aeroelastic loads analysis for three different gust lengths, as prescribed by the CS-25, are presented and discussed.<\/p>\n\n\n\n<p><a href=\"https:\/\/aerospacerepository.org\/wp-content\/uploads\/2024\/08\/IFASD-2017-200.pdf\">Read the full paper here<\/a><\/p>\n\n\n\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>C.
