The nonlinear system response for a variation of the Mach number and the mean angle of attack is investigated. Subcritical bifurcations and hystereses occur for both bifurcation parameters. The observed LCOs occur in the vicinity of the laminar drag bucket and are associated with signi\ufb01cant changes in frequencies and phase differences between airfoil motion and aerodynamic forces. The results indicate a strong correlation between the shock-boundary layer interaction and the observed aeroelastic instability.<\/p>\n\n\n\n<p><a href=\"https:\/\/aerospacerepository.org\/wp-content\/uploads\/2025\/02\/IFASD-2019-133.pdf\">Read the full paper here<\/a><\/p>\n\n\n\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>Marc Braune, Anne Hebler<\/b><\/p>\n<p>DOI Number: N\/A<\/p>\n<p> Conference number: IFASD-2019-133<\/p>\n","protected":false},"author":2,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[2433,2455],"tags":[638,2117,2377,2990,2989,2118],"class_list":["post-19060","post","type-post","status-publish","format-standard","hentry","category-1-ifasd-2019","category-unsteady-laminar-flow","tag-hysteresis","tag-laminar-airfoil","tag-limit-cycle-oscillation-2","tag-nonlinear-system-response","tag-subcritical-bifurcation","tag-transonic-flow-2","category-2433","category-2455","description-off"],"_links":{"self":[{"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/19060","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=19060"}],"version-history":[{"count":1,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/19060\/revisions"}],"predecessor-version":[{"id":19062,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/19060\/revisions\/19062"}],"wp:attachment":[{"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/media?parent=19060"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/categories?post=19060"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/tags?post=19060"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
