Capsule geometry was defined based on three-dimensional axisymmetric Viking geometry having five design parameters. Automatic surface meshing was carried out using a script that creates a p3d format and converts it to unstructured triangular surface mesh. Aero-thermal analysis was carried out using an engineering code that uses the local surface inclination method to estimate inviscid pressure and reference temperature method to calculate the skin friction coefficient. A streamline tracing method was implemented to calculate the local Reynolds number. Stagnation heat flux was estimated using the Brandis formula. Re-entry capsule geometry was optimized in the flow condition of Mach 20, angle of attack 20 deg, and altitude 57km using a multi-objective evolutionary algorithm. The optimum solution was selected considering the maximum lift-drag ratio, volumetric efficiency, and minimum stagnation heat flux.<\/p>\n\n\n\n<p><a href=\"https:\/\/aerospacerepository.org\/wp-content\/uploads\/2024\/05\/HiSST-2024-46.pdf\">Read the full paper here<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>Minsul LEE, Kyu Hong KIM, Hyoungjin KIM<\/b><\/p>\n<p>DOI Number: N\/A<\/p>\n<p>Conference number: HiSST-2024-046<\/p>\n","protected":false},"author":2,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[993,1409,1407],"tags":[1462,1463,1464,684],"class_list":["post-16712","post","type-post","status-publish","format-standard","hentry","category-events","category-high-speed-aerodynamics-and-aerothermodynamics-11-hisst-2024","category-11-hisst-2024","tag-cfd-analysis","tag-flow-through-model-analysis","tag-internal-drag-correction","tag-wind-tunnel-test","category-993","category-1409","category-1407","description-off"],"_links":{"self":[{"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/16712","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=16712"}],"version-history":[{"count":2,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/16712\/revisions"}],"predecessor-version":[{"id":21040,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/16712\/revisions\/21040"}],"wp:attachment":[{"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/media?parent=16712"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/categories?post=16712"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/tags?post=16712"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
