    摘要： A powerplant (20) is provided that includes a flowpath (40), a combustor (46) and a water extraction system (50). The combustor (46) is configured to generate combustion products and direct the combustion products through the flowpath (40). The combustion products are configured from or otherwise include water vapor. The water extraction system (50) is arranged with the flowpath (40) downstream of the combustor (46). The water extraction system (50) includes a condensation seeder and a collector (54). The condensation seeder is configured to direct a plurality of small water droplets (58) into the flowpath (40) to promote condensation of the water vapor to grow the small water droplets (58) into a plurality of large water droplets (60). The collector (54) is configured to collect the large water droplets (60).

    摘要： A gas turbine engine includes a core engine that includes a core flow path (C) that connects a compressor section (24), combustor section (26) and a turbine section (28). The gas turbine engine further includes a bottoming cycle system (62) that includes a supercritical CO2 (sCO2) working fluid flow (72; 74). A first recuperator (68) is disposed in the core flow path (C) downstream of the turbine section (28), the first recuperator (68) is configured to transfer thermal energy from a core flow aft of the turbine section (28) to the sCO2 working fluid flow. A second recuperator (70) is disposed in the compressor section (24), the second recuperator (70) is configured to transfer thermal energy from the sCO2 working fluid flow (72; 74) to a location forward of the combustor section (26).

    摘要： The invention provides a solar/air turbine generator system that reduces construction and power generating costs and does not require the use of fossil fuel. A solar/air turbine generator system comprises: a compressor 1 for drawing in and compressing air; a solar receiver 29 for heating the air compressed by the compressor 1 with the use of solar heat collected by a solar collector; an air turbine 2 for driving the compressor 1 and a generator by receiving the compressed air heated by the solar receiver 29; a regenerative heat exchanger, located between the compressor 1 and the solar receiver 29, for heating the air compressed by the compressor 1 using the exhaust of the air turbine 2 as a heating medium; and a distribution device, located between the compressor and the regenerative heat exchanger, for distributing the compressed air to the side of the regenerative heat exchanger and to a bypass side, the bypass side being the inlet side of the air turbine. The solar/air turbine generator system further includes a control device for maintaining the air temperature at the inlet of the air turbine at a constant value by adjusting the flow rate of the air turbine exhaust that flows into the regenerative heat exchanger as a heating medium.
