A turbofan gas turbine propulsion engine includes a system to transfer power from the low pressure turbine to the high pressure turbine and/or extract additional load from the low pressure turbine during certain turbofan engine operational conditions. The systems include a hydrostatic power transfer system that includes a hydraulic pump and a hydraulic motor coupled to the low pressure and high pressure turbine, respectively. The systems additionally include a mechanical and electrical load shifting/loading sharing systems that use clutches and gear asse...
We claim: 1. A multi-spool gas turbine engine, comprising: a differential gear assembly having a first input and a second input, the gear assembly configured, upon rotation of the first input, the second input, or both inputs, to supply a rotational drive force at a first rotational speed; a generator coupled to receive the rotational drive force supplied from the differential gear assembly and operable, upon receipt thereof, to generate electrical energy; a high pressure turbine coupled to the differential gear assembly first input and adapted to recei...
