The High Enthalpy Shock Tunnel G\u00f6ttingen, HEG, is one of the major European hypersonic test facilities of this kind. In high enthalpy testing, thermocouples and thin film gauges guarantee fast response times in the order of a few microseconds and therefore a high temporal resolution, but the spatial resolution is limited and can only be increased by increasing the number of sensors installed in a wind tunnel model. Additionally, it is challenging to attach these sensors on complex or sharp-edged models. A very promising but experimentally challenging non-intrusive option is the use of the temperature-sensitive paint technique (TSP). The application of TSP enables the measurement of spatially resolved surface temperatures and allows for the subsequent determination of surface heat fluxes. The development of this technique with a special focus on high repetition rates because measurement times in high enthalpy testing is typically less than 1 millisecond will be reviewed in this paper and the application possibilities will be outlined. Selected applications in HEG over the last decade will be discussed and the newest development of the TSP towards high temperatures which are encountered in flight will be presented and results of an application will be shown.<\/p>\n\n\n\n<p><a href=\"https:\/\/aerospacerepository.org\/wp-content\/uploads\/2024\/06\/HiSST-2024-277.pdf\">Read the full paper here<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>Jan MARTINEZ SCHRAMM, Divek SURUJHLAL, Leni SCHMIDT<\/b><\/p>\n<p>DOI Number: N\/A<\/p>\n<p>Conference number: HiSST-2024-277<\/p>\n","protected":false},"author":2,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[993,1407,1415],"tags":[1821,1820,459,1686],"class_list":["post-17213","post","type-post","status-publish","format-standard","hentry","category-events","category-11-hisst-2024","category-testing-evaluation","tag-high-enthalpy-shock-tunnel-gottingen","tag-high-temperature-high-enthalpy-testing","tag-hypersonic-flow","tag-temperature-sensitive-paint","category-993","category-1407","category-1415","description-off"],"_links":{"self":[{"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/17213","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=17213"}],"version-history":[{"count":2,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/17213\/revisions"}],"predecessor-version":[{"id":20614,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/17213\/revisions\/20614"}],"wp:attachment":[{"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/media?parent=17213"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/categories?post=17213"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/tags?post=17213"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
