This instability has to be evaluated early in<br>the design phase, thereby raising a need for fast and robust prediction methods. The key to analyzing such instability is the modeling of the motion-induced aerodynamic loads on the propeller. This paper proposes to build and compare different aerodynamic modeling methods ranging from low- to mid-fidelity. The comparison of the resulting stability boundaries shows that certain low-fidelity models give results close to mid-fidelity, emphasizing the advantages of these fast low-fidelity methods for the whirl flutter prediction. The interest of mid-fidelity modeling techniques in the study of non-conventional situations is also looked at. In particular, the occurrence of whirl flutter under non-axial flow is studied. The obtained stability boundaries highlight a slight stabilizing influence, demonstrating that the axial flight situation remains a conservative framework for whirl flutter studies.<\/p>\n\n\n\n<p><a href=\"https:\/\/aerospacerepository.org\/wp-content\/uploads\/2025\/04\/150.pdf\">Read the full paper here<\/a><\/p>\n\n\n\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>Vincent de Gaudemaris, Jean-S\u00e9bastien Schott\u00e9, Antoine Placzek, Laurent Blanc, Fabrice Thouverez<\/b><\/p>\n<p>DOI Number: https:\/\/doi.org\/10.82439\/ceas-ifasd-2024-150<\/p>\n<p>Conference number: IFASD-2024-150<\/p>\n","protected":false},"author":2,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[993,3022,3043],"tags":[1972,3140,3141,3142,3143,2875],"class_list":["post-19342","post","type-post","status-publish","format-standard","hentry","category-events","category-ifasd-2024","category-unsteady-cfd-1-ifasd-2024","tag-aeroelasticity","tag-low-fidelity","tag-mid-fidelity","tag-non-axial-flow","tag-pulse-method","tag-whirl-flutter","category-993","category-3022","category-3043","description-off"],"_links":{"self":[{"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/19342","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=19342"}],"version-history":[{"count":2,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/19342\/revisions"}],"predecessor-version":[{"id":20325,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/19342\/revisions\/20325"}],"wp:attachment":[{"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/media?parent=19342"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/categories?post=19342"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/tags?post=19342"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
