Summary

The Langley Research Center's 2.4-m (8-ft) high-temperature structures tunnel (HTST) is a Mach 7, blowdown wind tunnel used to investigate aerothermal-structural phenomena on large- to full-scaled high-speed vehicle components. The high-energy test medium, which provides a true-temperature simulation of hypersonic flow at 24-40 km altitude, is generated by the combustion of methane with air at high pressures. Since the wind tunnel, as well as the models, must be protected from thermally induced damage, ceramics and coatings have been used extensively. The details of in-service applications, operating conditions, behavior of the ceramics and coatings used to date, and planned applications are presented and discussed.
