The flow quality and characterization is of utmost<br>importance for the ground testing experiment. The paper is looking at the expansion flow in a<br>hypersonic nozzle and presents a methodology to determine the stability characteristics of the boundary<br>layer developing along the nozzle wall. It offers the occasion to discuss and investigate how the<br>turbulent boundary layers generated in a hypersonic nozzle. The selected test case is that of the<br>accelerating flow within the axially contoured nozzle of the VKI Longshot facility. The design of its<br>nozzle profile is first presented followed by the experimental characterization of its expansion flow inside<br>the nozzle. The stability analysis of the nozzle wall boundary layer is finally exposed with a discussion<br>on the physical mechanisms responsible for the development of instabilities.<\/p>\n\n\n\n<p><a href=\"https:\/\/aerospacerepository.org\/wp-content\/uploads\/2023\/10\/HiSST-2022-453.pdf\" data-type=\"link\" data-id=\"https:\/\/aerospacerepository.org\/wp-content\/uploads\/2023\/10\/HiSST-2022-453.pdf\">Read the full paper ><\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>Olivier Chazot, Geoffrey Andrews, D\u00e1niel G.
