This paper presents USYD Rocketry Team&#8217;s unique in-house developed trajectory and aerodynamic simulator for high-power rockets, known as Ironbark. Inviscid aerodynamic simulations are conducted in Ironbark using the higher-order panel code PANAIR and the viscous drag contribution is added using common analytical equations. A custom six-degree-of-freedom simulation is used for trajectory modelling. Ironbark is shown to reproduce aerodynamic results to available experimen\u00adtal data confirming its credibility. Finally, Ironbark&#8217;s apogee prediction for Bluewren, the 2022 winning Spaceport America Cup rocket, is presented and discussed.<\/p>\n\n\n\n<p><a href=\"https:\/\/www.eucass.eu\/doi\/EUCASS2023-011.pdf\">Read the full paper here<\/a><\/p>\n\n\n\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>MITCHELL GALLETLY; WILLIAM GIANG<\/b><\/p>\n<p>DOI Number: 10.13009\/EUCASS2023-011<\/p>\n","protected":false},"author":2,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[3766,993,3783],"tags":[3802,3803,601],"class_list":["post-25392","post","type-post","status-publish","format-standard","hentry","category-1-aerospace-europe-conference-2023","category-events","category-17-system-integration","tag-aerodynamic-modelling-high-power-rocket","tag-student-team","tag-trajectory-simulation","category-3766","category-993","category-3783","description-off"],"_links":{"self":[{"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/25392","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=25392"}],"version-history":[{"count":1,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/25392\/revisions"}],"predecessor-version":[{"id":25393,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/25392\/revisions\/25393"}],"wp:attachment":[{"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/media?parent=25392"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/categories?post=25392"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/tags?post=25392"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
