SUPERCRITICAL CO2 CYCLE AND INTEGRATED AUXILIARY POWER FOR GAS TURBINE ENGINES

Waste heat management systems are described. The waste heat management systems include a turbine engine (500) having a compressor section, a combustor section, a turbine section, and a nozzle (520). The compressor section, the combustor section, the turbine section, and the nozzle define a core flow path that expels through the nozzle (520). The waste heat management systems also include an auxiliary power unit (APU) system (540) and a waste heat recovery system (502) operably connected to the APU system (540). The APU system is integrated into a working fluid flow path (522) of the waste heat recovery system (502).
