The conventional ultimate performance test by applying a component in its true application (i.e., in an engine) is often very expensive and impractical when dealing with developmental materials. Simpler, less expensive, and more practical test methods must be utilized. The present work aims toward the applications of an innovative methodology for testing environmental performance of advanced Ceramic Matrix Composites (CMCs) in the presence of combined mechanical, thermal, and environmental applied conditions. To obtain a comprehensive understanding of how a composite might perform in certain application environments, a newly developed environmental performance testing system, which is able to provide the fundamental damage information of the composites in simulating service environments including variables such as temperature, mechanical and thermal stresses, flowing oxidizing gases and high gas pressure, is proposed. The system comprises of two subsystems: (1) equivalent experimental simulating subsystem, and (2) wind tunnel experimental simulating subsystem. The evolution mechanisms of the composites properties and microstructures can be achieved by the former, and then be validated and modified by the latter. Various loading (e.g. fatigue, creep), various atmospheres (e.g. argon, oxygen, water vapor, wet oxygen and molten salt vapor) and various temperature conditions (e.g. constant or cyclic temperatures) can be conducted on the system. Some typical experimental results are presented in this paper. Large quantities of tests have demonstrated the extraordinary stability and reliability of the system.

Continued regulatory pressure necessitates the use of precisely designed turbochargers to create the design trapped equivalence ratio within large-bore stationary engines used in the natural gas transmission industry. The upgraded turbochargers scavenge the exhaust gases from the cylinder, and create the air manifold pressure and backpressure on the engine necessary to achieve a specific trapped mass. This combination serves to achieve the emissions reduction required by regulatory agencies. Many engine owner/operators request that an upgraded turbocharger be tested prior to installing the turbocharger on the engine. The purpose of the test is to prevent field hardware iterations that are oftentimes necessary for the turbocharger to meet the air specification on the particular engine. Reworking a turbocharger due to not meeting the airflow and pressure requirement for emissions purposes can be quite costly and in many cases easily discovered through test-cell performance testing. Confirming the as-built turbocharger design specification prior to transporting the turbocharger to the field can decrease downtime and installation costs. There are, however, technical challenges that must be overcome to compare test-cell data to field conditions. This paper discusses the corrections that must be made to the test-cell data in order to determine how the turbocharger will perform on the engine. As the litmus test of the new testing system, performance data is corrected to site conditions verifying the air specification as designed by the end user. The correction method utilized herein is the ASME Power Test Code 10 (PTC-10) version 1997. Performance test data and the compressor map are corrected with the PTC-10 method to field conditions verifying turbocharger site performance before installation. After installation, data collected from the turbocharger operating on engine is compared with test corrected data, authenticating the turbocharger testing system and correction methods.
