SUITABILITY OF A NEW GLASS-CERAMIC MATERIAL FOR APPLICATION IN A ROTARY REGENERATOR DISC OPERATING AT 1850°F

The paper describes the factors which must be considered when assessing the suitability of a material for a rotary regenerator disc which runs at 1850°F.

Mechanical and thermal stressing, thermal stability, and corrosion resistance are analyzed, using the properties of type CPD-5 material. This is a new lithium-alumino-silicate glass ceramic developed by Corning Glass Works.

The environmental conditions assumed are those found in the 2500°F turbine inlet temperature engine which is being developed by the Ford Motor Company.
