A Study of Ceramic Liners for Uncooled Rocket Motor Chambers

The purpose of this study was to test certain ceramic liner materials in a liquid propelled, uncooled rocket motor chamber to determine the best type liner material and study the temperatures encountered on the chamber casing wall and the outer ceramic liner wall. The liner materials zirconia, zircon, beryllia and silicon carbide were tested in a stationary test rocket motor using acid-aniline propellant. From this study it was determined that rocket motors using a zirconia chamber liner and operated under test conditions could be fired for periods up to approximately 220 seconds.
