To analyze and understand the impact of reusability on launch systems, the DLR is conducting<br>studies of reusable space transportation configurations. In this context, a range of promising semireusable launch vehicles with a winged reusable first stage and either one or two expendable upper<br>stages for an injection into a geostationary transfer orbit (GTO) were designed and investigated.<br>Different engine and propellant combinations, using either LOX-LH2 or LOX-LCH4, were studied in order<br>to identify potentials and drawbacks of each combination. The winged first stage is recovered by the<br>\u201cIn-Air-Capturing\u201d method which is currently studied in the framework of the Horizon 2020 funded<br>project FALCon. A special focus is put onto the aerodynamic behavior of the winged stages. Since the<br>stage performs a mostly aerodynamically controlled re-entry, transitioning from supersonic velocity of<br>Mach 6-9 down to subsonic velocity, the vehicle has to be controllable throughout a vast range of<br>different aerodynamic states. Therefore, a reference stage from the system analysis is selected and<br>subjected to an investigation of dynamic behavior, controllability and stability along a reference<br>trajectory. The insights from this analysis shall be used to re-evaluate the system design and determine<br>implications on a system level.<\/p>\n\n\n\n<p><a href=\"https:\/\/aerospacerepository.org\/wp-content\/uploads\/2023\/10\/HiSST-2022-186.pdf\" data-type=\"link\" data-id=\"https:\/\/aerospacerepository.org\/wp-content\/uploads\/2023\/10\/HiSST-2022-186.pdf\">Read the full paper > <\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>Sven Stappert, Martin Sippel, Steffen Callsen, Leonid Bussler<\/b><\/p>\n<p>DOI Number XXX-YYY-ZZZ<\/p>\n<p>Conference Number HiSST-2022-186<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[993,1006,1010],"tags":[909,604,1124,1125,733,1123],"class_list":["post-16173","post","type-post","status-publish","format-standard","hentry","category-events","category-hisst-2022","category-hypersonic-fundamentals-and-history-hisst-2022","tag-flight-dynamics","tag-in-air-capturing","tag-lox-lch4","tag-lox-lh2","tag-reentry","tag-reusability","category-993","category-1006","category-1010","description-off"],"_links":{"self":[{"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/16173","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\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/comments?post=16173"}],"version-history":[{"count":1,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/16173\/revisions"}],"predecessor-version":[{"id":16174,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/16173\/revisions\/16174"}],"wp:attachment":[{"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/media?parent=16173"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/categories?post=16173"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/tags?post=16173"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
