ABSTRACT:
A hybrid propulsion system particularly for automotive application including a subambient pressure cycle gas turbine engine having a primary turbine-compressor rotor assembly connected to a load shaft and a secondary turbine-compressor rotor assembly gas coupled with the primary rotor assembly, a flywheel rotatable with the secondary rotor assembly, and variable geometry nozzles at the turbines operative during engine operation at a steady state power output level to effect partial motive fluid expansion at the primary turbine to drive the load and the primary compressor and partial motive fluid expansion at the secondary turbine to drive the secondary compressor which maintains subambient pressure and during engine operation at a peak power output level to effect substantially total motive fluid expansion across only the primary turbine for increased power at the load shaft, the flywheel being operative during peak power level operation to drive the secondary compressor to maintain total motive fluid expansion to subambient pressure.
