The study is carried out in the wind tunnel MARHy located at the ICARE laboratory of<br>CNRS-Orleans. The facility can recreate the atmospheric re-entry flight of any vehicle in terms of viscous<br>parameter and Knudsen number. The present work was carried out at hypersonic flow condition with a<br>Mach number 20 and low density equivalent to 100 km of altitude. The model is a waverider optimized<br>for optimal Lift to Drag ratio at Mach 10 and 50 km of altitude. The objective of this work is to analyse<br>the behaviour of this waverider at high Mach number and altitude. The investigation of aerodynamic<br>forces shows the waverider falls down for angles of attack higher than 15\u00b0. To confirm and explain this<br>stall density inside the shock wave have been analysed from flow field a visualisation. This study shows<br>a phenomenon of separation bubble which imply a constant pressure at the waverider surface. The<br>bubble is observed thanks to luminosity intensity profiles and showing the displacement and increase of<br>this bubble with the local rarefaction degree. As a consequence the shear layer can not reattach due to<br>the separation bubble so the lift force decrease and the waverider falls down.<\/p>\n\n\n\n<p><a href=\"https:\/\/aerospacerepository.org\/wp-content\/uploads\/2024\/04\/HiSST-2022-413.pdf\">Read the full paper here<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>Hugo Noubel, Viviana Lago, C\u00e9line Baranger<\/b><\/p>\n<p>DOI Number XXX-YYY-ZZZ<\/p>\n<p>Conference Number HiSST-2022-413<\/p>\n","protected":false},"author":2,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1008,1006],"tags":[1325,1323,1324,609,632],"class_list":["post-16416","post","type-post","status-publish","format-standard","hentry","category-high-speed-aerodynamics-and-aerothermodynamics-hisst-2022","category-hisst-2022","tag-aerodynamic-forces","tag-mach-20-2","tag-rarefied-flows","tag-waverider","tag-wind-tunnel","category-1008","category-1006","description-off"],"_links":{"self":[{"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/16416","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=16416"}],"version-history":[{"count":2,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/16416\/revisions"}],"predecessor-version":[{"id":16503,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/16416\/revisions\/16503"}],"wp:attachment":[{"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/media?parent=16416"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/categories?post=16416"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/tags?post=16416"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
