Results of one task of the first phase of RP1187-2, High-Reliability Gas Turbine Combined-Cycle Development Program are presented. The purpose of this task is to identify and quantify the potential benefits of applying advanced-design, low-aspect ratio, high-throughput compressor technology to heavy-duty power generation combustion turbine engines. Such technology is being used in the aircraft industry with satisfactory performance. This task was undertaken in view of this experience and with the expectation that the adaptation of this technology to electric utility combustion turbine power plants could offer substantial improvements in plant reliability, availability, and maintainability in comparison with units now in service. Included in this task is the development of conceptual designs and performance parameters based on the advanced compressor design approach to provide input to the selection of the best compressor configuration to meet the reliability and efficiency goals set forth for the new engine and combined cycle. The work has progressed with the execution of a literature survey of advanced aircraft technology, low-aspect ratio designs, and the conceptual selection of aerodynamic stage parameters for first, middle, and last stages suitable for the 14:1 compressor pressure ratio requirement. Subsequent analyses identified key mechanical design requirements for blading and rotating elements of the design.
