Abstract

ABSTRACT Gas turbine engine efficiency, safety, and life cycle cost are directly influenced by the durability and performance of the turbine hot section. Numerous advances have been applied to improve the capabilities of turbines including new structural materials, innovative thermal barrier coatings, and advanced heat transfer techniques; however, improved designs are still dependent on accurate knowledge of true turbine environmental conditions during operation. In conjunction with ongoing advances in physics-based modeling, physical measurement of actual turbine conditions remains a necessity. The Small CAESAR project supports the demonstration and maturation of advanced components, including sensors, under the VAATE program. Sporian Microsystems provided smart pressure/temperature sensor suite probes for testing under Small CAESAR. These probes survived in situ conditions in three engine locations: compressor discharge, high pressure turbine inlet and low pressure turbine inlet, in a test designed to demonstrate TRL 6.
