Summary

Ceramic matrix composite (CMC) applied turbine shroud for next-generation super sonic transport propulsion system was investigated in ESPR program. Trial manufacture of model shrouds using 3D-SiC/SiC were conducted and evaluated their manufacturing processes by strength tests of joint portions with metal parts. Model shrouds were successfully manufactured in appearance and the strength of joint portions were confirmed to have enough strength for engine test. To protect CMC from high temperature gas, mullite material was coated on inner surface of shrouds. Using a flat specimen and a model shroud, thermal cycle durability of coated CMC were evaluated by burner rig test apparatus. There were no debonding after 500 cycles on each specimen. These test results showed that CMC shrouds were potentially applicable to engine test.
