Even at present, the trends in the aviation industry are to increase wing length (to reduce induced drag) and maximize use of composites, which lead to increased structural \ufb02exibility. This necessitates a rethink of conventional (linear) aeroelastic analysis, since the increased \ufb02exibility results in coupling between the \ufb02ight dynamic and aeroelastic dynamics, and consequently, limit-cycle oscillations of the structure. In this paper, a new three-dimensional low-order model for unsteady aerodynamics that accounts for large oscillation amplitudes and nonplanar wakes is developed. An experiment with a cantilevered \ufb02at plate at low Reynolds number is set up and used to validate the low-order model, as well as to study post-\ufb02utter limit-cycle oscillations. Results from the low-order model are promising, but show that aerodynamic nonlinearities such as \ufb02ow separation and leading-edge vortex shedding must also be modeled in order to predict all possible limit-cycle oscillations of the aeroelastic system.<\/p>\n\n\n\n<p><a href=\"https:\/\/aerospacerepository.org\/wp-content\/uploads\/2024\/08\/IFASD-2017-161.pdf\">Read the full paper here<\/a><\/p>\n\n\n\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>Kiran Ramesh, Tiago Priolli Monteiro, Fl\u00e1vio Jos\u00e9 Silvestre, Ant\u00f4nio Bernardo Guimar\u00e3es Neto, Thiago de Souza Siqueira Versiani, Roberto Gil Annes da Silva<b\/><\/p>\n<p>DOI Number: N\/A<\/p>\n<p>Conference number: IFASD-2017-161<\/p>\n","protected":false},"author":2,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[993,1961,1953],"tags":[2268,2266,2269,2012,2267],"class_list":["post-18073","post","type-post","status-publish","format-standard","hentry","category-events","category-highly-flexible-aircraft-structures","category-ifasd-2017","tag-cantilevered-plate","tag-exible-wings","tag-uid-structure-interaction-2","tag-hale","tag-leading-edge-vortices","category-993","category-1961","category-1953","description-off"],"_links":{"self":[{"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/18073","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=18073"}],"version-history":[{"count":1,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/18073\/revisions"}],"predecessor-version":[{"id":18075,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/18073\/revisions\/18075"}],"wp:attachment":[{"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/media?parent=18073"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/categories?post=18073"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/tags?post=18073"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
