A seven-year program, designated "Research & Development of Automotive Ceramic Gas Turbine Engine (CGT Program)", was started in June 1990 with the object of demonstrating the advantageous potentials of ceramic gas turbines for automotive use. This CGT-Program is conducted by PEC with the support of MITI. The basic engine is a 100-kW, single-shaft engine having a turbine inlet temperature of a 1350t and a rotor speed of 110,000 rpm. During the second year of the program, experimental evaluation
