A possibility for hypersonic passenger flights is the use of<br>scramjets that are powered by hydrogen combustion. Consequently, an improvement in performance<br>of spacecraft regarding their efficiency and flight time is an economic and social desire. While hydrogen<br>combustion has almost zero carbon dioxide output, water vapor and NO are formed in the process.<br>Both are believed to have a strong influence on the atmospheric chemistry [1]. Therefore, a precise<br>experimental determination of both NO and H2O production during the hydrogen combustion is<br>necessary for the evaluation of environmental effects caused by hydrogen fueled vehicles. To test these<br>models in the future in the High Enthalpy Shock Tunnel G\u00f6ttingen (HEG), being one of the major<br>European hypersonic test facilities, a novel experimental approach to study the development of gas<br>concentrations at rapid acquisition rates is the absorption spectroscopy with quantum cascade lasers<br>(QCLs) in the infrared regime [2].<\/p>\n\n\n\n<p><a href=\"https:\/\/aerospacerepository.org\/wp-content\/uploads\/2023\/10\/HiSST-2022-451.pdf\" data-type=\"link\" data-id=\"https:\/\/aerospacerepository.org\/wp-content\/uploads\/2023\/10\/HiSST-2022-451.pdf\">Read the full paper > <\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>Leni Schmidt and Jan Martinez Schramm<\/b><\/p>\n<p>DOI Number XXX-YYY-ZZZ<\/p>\n<p>Conference Number HiSST-2022-451<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1006,1013],"tags":[1385,672,1384,459,614],"class_list":["post-16477","post","type-post","status-publish","format-standard","hentry","category-hisst-2022","category-propulsion-systems-and-components-hisst-2022","tag-absorption-spectroscopy","tag-heg","tag-hydrogen-combustion","tag-hypersonic-flow","tag-scramjet","category-1006","category-1013","description-off"],"_links":{"self":[{"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/16477","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=16477"}],"version-history":[{"count":1,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/16477\/revisions"}],"predecessor-version":[{"id":16478,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/16477\/revisions\/16478"}],"wp:attachment":[{"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/media?parent=16477"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/categories?post=16477"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/tags?post=16477"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
