AUTOMOTIVE GAS TURBINE CERAMIC REGENERATOR DESIGN AND RELIABILITY PROGRAM Final Annual Report, July 1,1975-September 30,1976

摘要

The primary objective of the ERDA/Ford Ceramic Regenerator Design and Reli¬ability Program is to develop ceramic regenerator cores that can be used in passenger car gas turbine engines, Stirling engines, and industrial/truck gas turbine engines. Specific durability objectives are defined as achieving a B10 life of 10,000 hours on a truck/industrial gas turbine engine duty cycle.nPrevious reports, under this program, summarized operating experience on lithium aluminum silicate (LAS) ceramic regenerator cores obtained at Ford Motor Company. The primary cause of failure of these regenerators was determined to be chemical attack of the LAS 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.
