Multi-Objective Genetic Algorithm (MOGA) was used to<br>optimize various objective functions. To compute the objective functions, aerodynamic and thermal<br>analysis was performed during the re-entry process. The modified Newtonian flow and the approximate<br>convective-heating equation were used for aerothermodynamic analysis. After the thermal analysis was<br>performed, the wall temperature was calculated for designing the Thermal Protection System (TPS)<br>layout. Optimization was computed with KSP-1 provided by the Korea Aerospace Research Institute<br>(KARI) was used as a baseline configuration. According to the comparison geometry-based TPS layout<br>and wall temperature-based TPS layout, the wall temperature-based TPS layout was generally lower in<br>weight and protected high-temperature areas that the geometry-based TPS layout did not capture.<\/p>\n\n\n\n<p><a href=\"https:\/\/aerospacerepository.org\/wp-content\/uploads\/2024\/06\/HiSST-2024-273.pdf\">Read the full paper here<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>Dabeen JEONG, Shinkyu JEONG, Jongho JUNG<\/b><\/p>\n<p>DOI Number: N\/A<\/p>\n<p>Conference number: HiSST-2024-273<\/p>\n","protected":false},"author":2,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[993,1410,1407],"tags":[1043,1813,1812],"class_list":["post-17201","post","type-post","status-publish","format-standard","hentry","category-events","category-high-speed-missions-and-vehicles-11-hisst-2024","category-11-hisst-2024","tag-aerothermodynamics","tag-multi-objective-genetic-algorithm","tag-reusable-unmanned-space-vehicle","category-993","category-1410","category-1407","description-off"],"_links":{"self":[{"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/17201","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=17201"}],"version-history":[{"count":2,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/17201\/revisions"}],"predecessor-version":[{"id":20622,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/17201\/revisions\/20622"}],"wp:attachment":[{"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/media?parent=17201"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/categories?post=17201"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/tags?post=17201"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
