Inward-turning inlets offer high compression efficiency and mass capture but suffer from low-Mach starting difficulty due to that efficiency. Conventional single-point designs struggle with wide-speed-range performance. To address this, this paper proposes a wide-speed-range self-starting internal contraction inlet inverse design method based on the Double Design Points (DDP) concept. The method constructs a DDP self-starting basic flow field by controlling internal\/external compression strengths and generates the 3D inlet surface via the osculating method to inherit the flow field characteristics. Numerical<br>simulations confirm full mass flow capture at the high Mach number design point (Ma6) and self-starting capability at the low Mach number design point (Ma4.5). During starting, the large separation bubble causing unstart is gradually engulfed by the throat, shrinking into a small bubble. This provides a new approach to enhance inlet wide-speed-range capability.<\/p>\n\n\n\n<p><a href=\"https:\/\/aerospacerepository.org\/wp-content\/uploads\/2025\/10\/HISST2025_178_paper.pdf\">Read the full paper here<\/a><\/p>\n\n\n\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>Cai ZEJUN, Zheng XIAOGANG, Guo MENGLEI, Zhu WENLEI, Zhu CHENGXIANG, You YANCHENG<\/b><\/p>\n<p>DOI Number: N\/A<\/p>\n<p>Conference number: HiSST-2025-178<\/p>\n","protected":false},"author":2,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[993,3361,3363],"tags":[564,3598,3599],"class_list":["post-22839","post","type-post","status-publish","format-standard","hentry","category-events","category-1-hisst-2025","category-propulsion-systems-components","tag-hypersonic-vehicles","tag-self-starting","tag-speed-range","category-993","category-3361","category-3363","description-off"],"_links":{"self":[{"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/22839","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=22839"}],"version-history":[{"count":1,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/22839\/revisions"}],"predecessor-version":[{"id":22841,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/22839\/revisions\/22841"}],"wp:attachment":[{"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/media?parent=22839"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/categories?post=22839"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/tags?post=22839"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
