Compressor configuration and design optimiztion for the high reliability gas turbine. Final report

Technical Report ·
OSTI ID:7175220
This preliminary design study was conducted to define an advanced compressor for use in the High Reliability Combustion Turbine Engine presently investigated under EPRI contract RP1187-2. Advanced design concepts based on projections of 1985 low aspect ratio aircraft engine compressor technology were utilized to define three compressor configurations with 11, 13 and 15 stages. This study was applied to compressors with 14:1 pressure ratio, 800 lbs/sec (360 kg/sec) airflow and operating at 3600 rpm to match the requirements of heavy duty power generation combustion turbine engines. Typical, front, middle and last stages of these three compressors were studied to evaluate their aerodynamic and mechanical feasibility and to determine the influence of the number of stages, and stage loadings on their overall efficiency. The 11 stage compressor was selected for further mechanical analysis to verify its structural constraints and define in greater detail its mechanical configuration. Cost of this compressor was estimated for comparison with the present 19 stage High Reliability Reference Compressor derived from the Westinghouse W-501 engine. Finally, development requirements and a program schedule were established.
