摘要：

The operational map of the H3 Mach 6 blowdown wind tunnel, at the von Karman Institute for Fluid Dynamics (VKI), is extended towards lower Mach numbers with a new axisymmetric contoured nozzle to achieve Mach 5 testing conditions. Following the design, manufacturing, instrumentation and integration of the Mach 5 nozzle, an extensive commissioning campaign is initiated. The flow investigations rely on several intrusive and non-intrusive measurement techniques including free-stream static pressure measurements, a rake of pitot probes, total temperature probes and schlieren flow visualization. Results are compared with numerical predictions.
