Ceramic Matrix Composite Combustor Liner Rig Test

The NASA High Speed Research (HSR)/Enabling Propulsion Materials (EPM) program was charged with the responsibility for developing the materials and technologies necessary to meet the High Speed Civil Transport (HSCT) engine requirements. The combustor liner was identified as a critical component for meeting the efficiency and environmental acceptability goals of the HSCT engine. The EPM Ceramic Matrix Composite (CMC) Combustor liner program was tasked with developing and demonstrating a material system and design concept that meets the HSCT environmental, thermal, structural, economic, and durability requirements. Melt Infiltration (MI) SiC/SiC composites were ultimately selected for the combustor liner application. The culmination of this development effort was the delivery and testing of a CMC combustor liner. Testing was performed at NASA Glenn Research Center in the Sector Rig under HSCT operating conditions. The initial results of the rig testing are presented.Copyright © 2000 by ASME
