The velocity \ufb01eld is described by means of a complex potential, which is developed by mapping the airfoil boundary onto a circle. This well-established approach adopted in several small disturbance theories is generalized to airfoil motions of arbitrary amplitude, under the only assumptions of attached \ufb02ow and constant body length. Vorticity shedding from the airfoil trailing edge is modeled using a discrete-vortex method to account for non-planar wake. A semi-analytical solution for the pressure jump on the body is obtained that may be used for parametric studies and assessment of high-\ufb01delity solvers. Numerical results are presented for a cantilevered \ufb02exible airfoil undergoing imposed motion in a steady axial \ufb02ow.<\/p>\n\n\n\n<p><a href=\"https:\/\/aerospacerepository.org\/wp-content\/uploads\/2024\/08\/IFASD-2017-167.pdf\">Read the full paper here<\/a><\/p>\n\n\n\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>Cristina Riso, Giorgio Riccardi, Franco Mastroddi<b\/><\/p>\n<p>DOI Number: N\/A<\/p>\n<p>Conference number: IFASD-2017-167<\/p>\n","protected":false},"author":2,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[993,1953,1964],"tags":[2282,2281,2283,2001],"class_list":["post-18088","post","type-post","status-publish","format-standard","hentry","category-events","category-ifasd-2017","category-steady-unsteady-aerodynamics","tag-discrete-vortex-method","tag-flexible-airfoils","tag-free-wake","tag-unsteady-aerodynamics","category-993","category-1953","category-1964","description-off"],"_links":{"self":[{"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/18088","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=18088"}],"version-history":[{"count":1,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/18088\/revisions"}],"predecessor-version":[{"id":18090,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/18088\/revisions\/18090"}],"wp:attachment":[{"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/media?parent=18088"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/categories?post=18088"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/tags?post=18088"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
