The analysis of gust encounters on the NASA Common Research model (CRM), a typical transport aircraft con\ufb01guration, at transonic speed is conducted for two approaches employing time-linearized CFD and CFD-corrected DLM. The results are compared to nonlinear CFD and DLM simulations. The numerical prediction of gust loads requires the coupling of the disciplines aerodynamics, structural dynamics and \ufb02ight mechanics. The aeroelastic coupling is realized in the frequency domain and in the time domain in terms of generalized coordinates employing a \ufb02uid-structure feedback loop.<\/p>\n\n\n\n<p><a href=\"https:\/\/aerospacerepository.org\/wp-content\/uploads\/2024\/08\/IFASD-2017-101.pdf\">Read the full paper here<\/a><\/p>\n\n\n\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>Christoph Kaiser, Diliana Friedewald, Jens Nitzsche<b\/><\/p>\n<p>DOI Number: N\/A<\/p>\n<p>Conference number: IFASD-2017-101<\/p>\n","protected":false},"author":2,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[993,1957,1953],"tags":[1972,2143,2121,2144,2028,2142],"class_list":["post-17888","post","type-post","status-publish","format-standard","hentry","category-events","category-computational-aeroelasticity","category-ifasd-2017","tag-aeroelasticity","tag-dlm-correction","tag-gust-encounter","tag-nasa-common-research-model","tag-reduced-order-model-2","tag-time-linearized-cfd","category-993","category-1957","category-1953","description-off"],"_links":{"self":[{"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/17888","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=17888"}],"version-history":[{"count":1,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/17888\/revisions"}],"predecessor-version":[{"id":17890,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/17888\/revisions\/17890"}],"wp:attachment":[{"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/media?parent=17888"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/categories?post=17888"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/tags?post=17888"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
