Ceramic and coating applications in the hostile environment of a high temperature hypersonic wind tunnel [PDF]
A Mach 7, blowdown wind tunnel was used to investigate aerothermal structural phenomena on large to full scale high speed vehicle components. The high energy test medium, which provided a true temperature simulation of hypersonic flow at 24 to 40 km ...

Supersonic blowdown wind tunnel control using ABC optimized PID controller
International Journal of Aeronautics and AstronauticsSupersonic blowdown wind tunnels enable the testing of aircraft prototypes in the Mach 1.2 to 5 range, but these tunnels allow very limited test times due to their structure. In addition, once the wind tunnel system starts operating, the pressure in the tank where the air is stored changes constantly.

Effect of Reynolds number variation on aerodynamics of a hydrogen-fueled transport concept at Mach 6 [PDF]
Two separate tests have been made on the same blended wing-body hydrogen-fueled transport model at a Mach number of about 6 and a range of Reynolds number (based on theoretical body length) of 1.577 to 55.36 X 10 to the 6th power.
