A microturbine power generation system includes an electrical generator, a turbine and a compressor intermediate the generator and the turbine. The turbine, compressor and electrical generator are secured together by a tieshaft. The tieshaft is prestressed such that faces of the turbine, electrical generator and compressor maintain contact during high-speed, high-temperature operation of the system.
[What is claimed is:] [1.]a turbine for converting gaseous heat energy into mechanical energy;a power converter for converting the mechanical energy produced by the turbine into electrical energy, the power converter having a rotating portion and a non-rotating portion; anda single tieshaft having a diameter of less than about one-half inch, the tieshaft connecting the turbine and the rotating portion of the power converter, wherein, during operation of the microturbine power generating system, said tieshaft, turbine and rotating portion of the power con...
