A power generating system, including a first shaft, a first compressor, a second compressor and a turbine. In a further embodiment, the system also includes a second turbine, a second shaft and a generator. Each of the first compressor, the second compressor and the turbine are connected to the first shaft whereby the first shaft, the first compressor, the second compressor and the turbine all rotate at the same speed. The first compressor and second compressor are of disparate flow types.
