Abstract
Market demands new gas turbines or enhancement of an existing gas turbines to fulfill its demand from time to time. These demands are due to changing environmental regulations, market competition, energy efficiency, technological advancements, change in fuel type. Any new GT product enhancement requires validation to understand capability of subsystem behavior and to gain more confidence on performance improvement. Several instrumentations are required to measure these responses at identified locations from different subsystems in gas turbine during prototype testing. Gas turbine is tested with all these instrumentations with several variations in operating parameters to gather actual responses from gas turbine performance and its subsystem. These instruments require modification in subsystem components to gather data and cable routing to send these data to acquisition system. Pressure probes, thermocouples, strain gages, accelerometers, clearance probes, etc. are placed at the identified locations after necessary modifications in subsystem components. These modified features are validated through appropriate analytical assessments to ensure design robustness ensuring successful test campaign and data acquisition. This paper describes those analytical assessments ensuring design robustness.
