Abstract:
1. An apparatus comprising: a gas turbine engine comprising a combustor, a high pressure spool and a low pressure spool, wherein the high pressure spool comprises a high pressure turbine, wherein the low pressure spool comprises a low pressure turbine, wherein the low pressure turbine is downstream of the high pressure turbine, and wherein the low pressure turbine is operable to convert energy from a working fluid of the gas turbine engine into a mechanical energy; an electrical generator coupled to the low pressure turbine for converting the mechanical energy into an electrical energy; and an energy transferring device comprising an electrical heater and a power allocation circuit; wherein the energy transferring device receives electrical energy from said generator, wherein the heater is in thermal communication with the working fluid, wherein the power allocation circuit is programmed to allocate the electrical energy in selectable ratios between the heater and an electrically powered system external to the gas turbine engine.
