Typically, the unsteady aerodynamics for gust loads are computed by the Doublet Lattice Method. However, this method does not account for effects, which are important from a \ufb02ight dynamics and manoeuvre loads perspective. E.g., the roll-yaw coupling, also responsible for the \ufb02ight mechanical eigenmodes like the dutch roll mode, are unaccounted for by the DLM. Since, the dutch roll mode might also be excited by lateral gusts, this might have an in\ufb02uence on the loads response. In this paper, the unsteady aerodynamics are computed by a 3D panel method, capable of capturing the \ufb02ight dynamics accurately and provide complex Aerodynamics In\ufb02uence Coef\ufb01cients for gust loads analysis as a function of reduced frequency similar to the DLM. The aerodynamics of the panel method are validate by comparison with CFD results. Differences in the \ufb02ight mechanics between the DLM and the panel methods are assessed for a parametric variation of the wing dihedral of an aircraft model. Finally, results from a frequency domain gust loads analysis of a lateral gust for the DLM and the 3D panel method are compared.<\/p>\n\n\n\n<p><a href=\"https:\/\/aerospacerepository.org\/wp-content\/uploads\/2024\/08\/IFASD-2017-107.pdf\">Read the full paper here<\/a><\/p>\n\n\n\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>Thiemo M.
