Abstract
A method providing electric power with a system including a generator, and a single power shaft assembly having a compressor, turbine, combustor feeding the turbine, and drive coupling between the turbine, compressor, and generator. The method includes providing at least one additional shaft assembly including at least one combination of an intercooler feeding a compressor, at least one combination of a combustor feeding a turbine, and a drive coupling between at least one turbine of the at least one additional shaft assembly and at least one compressor of the at least one additional shaft assembly; providing a recuperator; connecting the power shaft assembly, the at least one additional shaft assembly, and the recuperator to define a thermal cycle with an air and gas path through the compressor of the power shaft assembly, the intercooler and compressor of the at least one additional shaft assembly, recuperator, combustor and turbine of the at least one additional shaft assembly, and the combustor and turbine of the power shaft assembly; ensuring that a total pressure ratio of all compressors of the at least one additional shaft assembly is greater than a total expansion ratio of …
