The full aircraft application case with aspect ratio 17 is used to show the relevance of mass- and altitude-dependent unsteady aerodynamics, but it also shows that for a relatively flexible wing nonlinear structural effects cannot be neglected. For the aerodynamic modelling, linearised RANS CFD aerodynamics are used. A detailed FEM is employed for structural modelling, which is deformed according to the steady conditions to cover geometric nonlinearities in the flutter process.<\/p>\n\n\n\n<p><a href=\"https:\/\/aerospacerepository.org\/wp-content\/uploads\/2025\/04\/169.pdf\">Read the full paper here<\/a><\/p>\n\n\n\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>Bernd Stickan, Reik Thormann, Michael Wrightson, Paolo Mastracci, Thomas Wilson<\/b><\/p>\n<p>DOI Number: https:\/\/doi.org\/10.82439\/ceas-ifasd-2024-169<\/p>\n<p>Conference number: IFASD-2024-169<\/p>\n","protected":false},"author":2,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[993,3028,3022],"tags":[1972,2273,2828,2058,2261,2021],"class_list":["post-19300","post","type-post","status-publish","format-standard","hentry","category-events","category-computational-aeroelasticity-1-ifasd-2024","category-ifasd-2024","tag-aeroelasticity","tag-flutter-analysis","tag-lfd","tag-linearized-cfd","tag-rom","tag-structural-dynamics","category-993","category-3028","category-3022","description-off"],"_links":{"self":[{"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/19300","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/comments?post=19300"}],"version-history":[{"count":2,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/19300\/revisions"}],"predecessor-version":[{"id":20340,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/19300\/revisions\/20340"}],"wp:attachment":[{"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/media?parent=19300"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/categories?post=19300"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/tags?post=19300"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
