Air enters the centrifugal compressor, where it is compressed to approximately 3 atmospheres. On its way to the combustor, it is pre-heated by engine exhaust heat in a recuperator, reducing the amount of required fuel by about one third. The pre-heated air enters the combustor along with fuel, where it is ignited. Following ignition, it expands through the turbine, providing work to both drive the compressor and the integrated PM generator. Exhaust air from the turbine passes through the recuperator, which is used to pre-heat compressor discharge air.
The electrical power is conditioned in an inverter, providing appropriate power type (AC or DC) and level depending on the application.
The PM generator also serves as a motor, which is used to start the engine.
