The single-diaphragm<br>combustion-driven shock tube operating mode was initially investigated. Both driver and driven sections<br>were instrumented with pressure transducers. The combustion driver was filled with a pressurized<br>stoichiometric mixture of Hydrogen and Oxygen diluted in Helium, which was ignited through specially<br>built spark plugs evenly distributed along the driver tube wall. Mixture dilutions of 65% and 75% were<br>investigated with filling pressure up to 3.0 MPa. The shock tube performance was also evaluated in<br>terms of incident shock wave velocity. Diaphragm rupture behaviour was assessed for several<br>operational conditions, in order to minimize diaphragm debris formation and to guarantee repeatable<br>flow conditions. In addition, the combustion-driven shock tunnel safety procedures were practiced<br>starting from milder configurations before ramping up the operating conditions.<\/p>\n\n\n\n<p><a href=\"https:\/\/aerospacerepository.org\/wp-content\/uploads\/2024\/05\/HiSST-2024-123.pdf\">Read the full paper here<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>Marco A.
