Dynamic, flexible ceramic seals developed for use at high temperatures in high-performance, variable-geometry, hypersonic airplane engines. Stacked ceramic wafers pressed against stationary sidewall by pressure in one or more metal bellows. Seals also used in hypersonic engines, two-dimensional convergent/divergent and vectored-thrust exhaust nozzles, airframes of reentry vehicles, casings of rocket motors furnaces, and other applications.
