Its main objective is to enhance the EU hypersonic testing capabilities by designing hypersonic quiet wind tunnels. Such state-of-the-art facilities are crucial to replicate the flight conditions of hypersonic cruise and re-entry vehicles, for which traditional wind tunnels fail to generate correct free-stream disturbance levels. By focusing on both low-enthalpy and the more challenging flight-enthalpy quiet tunnel designs, SILENT addresses a strategic, technological and operational need in the EU defense and research sector. This paper outlines the project goals, its methodology and expected outcomes, while covering the links to<br>application requirements and to the current state-of-the-art. The potential for disruptive innovation in hypersonic technologies, enhanced vehicle design capabilities and strengthened European defence and civil R&amp;D collaborations are highlighted.<\/p>\n\n\n\n<p><a href=\"https:\/\/aerospacerepository.org\/wp-content\/uploads\/2025\/10\/HISST2025_31_paper.pdf\">Read the full paper here<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>Mathieu LUGRIN, Jose CARDESA, Guillaume GROSSIR, Pierre SCHROOYEN, Alexander THEISS, Jens LUNTE, Lorenzo TARCHI, Julien LEFIEUX, Lauren DELAGE<\/b><\/p>\n<p>DOI Number: N\/A<\/p>\n<p>Conference number: HiSST-2025-031<\/p>\n","protected":false},"author":2,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[993,3367,3361],"tags":[440,607,580],"class_list":["post-23241","post","type-post","status-publish","format-standard","hentry","category-events","category-high-speed-aerodynamics-and-aerothermodynamics-with-application-to-hypersonic-regimes","category-1-hisst-2025","tag-hypersonic","tag-stability","tag-transition","category-993","category-3367","category-3361","description-off"],"_links":{"self":[{"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/23241","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=23241"}],"version-history":[{"count":1,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/23241\/revisions"}],"predecessor-version":[{"id":23243,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/23241\/revisions\/23243"}],"wp:attachment":[{"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/media?parent=23241"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/categories?post=23241"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/tags?post=23241"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
