The aircraft is shaked with actuators to measure its vibration modes (like a guitar harmonic). Once done, a quite tricky calculation allows to correlate aerodynamic behavior with vibrations modes measured previously. In this way, engineers are deducing the risks of flutter and, if required, are modifying the aircraft to remove the behavior.<\/span><\/span><\/div>\n<\/div>\n<div class=\"\" data-block=\"true\" data-editor=\"53jel\" data-offset-key=\"ajmi9-0-0\">\n<div class=\"_1mf _1mj\" data-offset-key=\"ajmi9-0-0\"><span data-offset-key=\"ajmi9-0-0\">&nbsp;<\/span><\/div>\n\n<div class=\"_1mf _1mj\" data-offset-key=\"ajmi9-0-0\">&nbsp;<\/div>\n<div class=\"_1mf _1mj\" data-offset-key=\"ajmi9-0-0\"><span style=\"font-size: 13px;\">Hurry up to pre-order (with no obligation), deliveries for 2019 are almost fully booke<\/span><span style=\"font-size: 13px;\">d!<\/span> It&#8217;s <a href=\"https:\/\/elixir-aircraft.com\/cms\/english-categories\/how-to-buy\/\">HERE<\/a>!<span style=\"font-size: 14px;\"><br><\/span><\/div>\n<\/div>\n<\/div>\n<\/div>\n\n\n\n<div style=\"text-align: justify;\"><hr><strong>Stay tuned<\/strong><\/div>\n\n\n\n<div style=\"text-align: justify;\">Arthur L\u00e9opold-L\u00e9ger &#8211; Nicolas Mahuet &#8211; Cyril Champenois<\/div>\n","protected":false},"excerpt":{"rendered":"<p><span data-offset-key=\"4kffl-0-0\"><span data-text=\"true\">How engineers are identifying flutter on an aircraft (dangerous vibrations happening in flight)? <\/span><\/span><\/p>\n","protected":false},"author":3,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"_breakdance_hide_in_design_set":false,"_breakdance_tags":"","footnotes":""},"categories":[164],"tags":[],"class_list":["post-249","post","type-post","status-publish","format-standard","hentry","category-news"],"acf":[],"lang":"en","translations":{"en":249,"fr":250},"pll_sync_post":[],"_links":{"self":[{"href":"https:\/\/elixir-aircraft.com\/wp-json\/wp\/v2\/posts\/249","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/elixir-aircraft.com\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/elixir-aircraft.com\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/elixir-aircraft.com\/wp-json\/wp\/v2\/users\/3"}],"replies":[{"embeddable":true,"href":"https:\/\/elixir-aircraft.com\/wp-json\/wp\/v2\/comments?post=249"}],"version-history":[{"count":2,"href":"https:\/\/elixir-aircraft.com\/wp-json\/wp\/v2\/posts\/249\/revisions"}],"predecessor-version":[{"id":1127,"href":"https:\/\/elixir-aircraft.com\/wp-json\/wp\/v2\/posts\/249\/revisions\/1127"}],"wp:attachment":[{"href":"https:\/\/elixir-aircraft.com\/wp-json\/wp\/v2\/media?parent=249"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/elixir-aircraft.com\/wp-json\/wp\/v2\/categories?post=249"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/elixir-aircraft.com\/wp-json\/wp\/v2\/tags?post=249"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
