CERAMIC REGENERATOR SYSTEMS DEVELOPMENT PROGRAM
The primary objectives of the DOE/NASA Ceramic Regenerator Design and Reliability Program is to develop ceramic regenerator cores that can be used in passenger car and industrial/truck gas turbine engines. The major cause of failure of early gas turbine regenerators was found to be chemical attack of the ceramic material. Improved materials and design concepts aimed at reducing or eliminating chemical attack were placed on durability test in Ford 707 industrial gas turbine engines late in 1974. This report describes the results of 10,745 hours of turbine engine durability testing accumulated during the period from July 1, 1978 to Dec. 31, 1978. Two materials, aluminum silicate and magnesium aluminum silicate, continue to show promise. Three aluminum silicate cores have attained the durability objective of 10,000 hours at 800C (1472F). Another aluminum silicate core shows minimal evidence of chemical attack after 7632 hours at 982C (1800F). The results obtained during the period in ceramic material screening tests, aerothermodynamic performance tests, stress analysis, cost studies, and material specifications are also included in this report.
