摘要： A heat engine utilizing a cycle having an isenthalpic pressure-increasing phase wherein, in the entropy-reduction phase of the cycle for changing the state of the working fluid, in order to have at least a part of that phase change at constant enthalpy, a compensating fluid (high-pressure feed) at a pressure higher than that of the cycle working fluid is introduced into the cycle system at the beginning of the isenthalpic change, thus increasing the pressure of the working fluid, and then the entropy of the working fluid is reduced by discharging a part of the working fluid to the outside of the cycle system at the end of the isenthalpic change.

摘要： Systems and methods relating to variable pressure turbines are disclosed. A power generation system may include a closed cycle system configured to generate power, a combustor, and a control system. The closed cycle system may include a working fluid circulating in a closed cycle path. The combustor may provide thermal energy to the working fluid. Further, the control system may be configured to determine to increase an amount of power generated by the closed cycle system, and in response to the determination to increase the amount of power generated by the closed cycle system, cause an increase in pressure of the working fluid in the closed cycle path.

摘要： Aircraft power plants including combustion engines (18), and associated methods for recuperating waste heat from such aircraft power plants are described. A method includes transferring the heat rejected by the internal combustion engine (18) to supercritical CO 2 (sCO 2 ) used as a working fluid in a heat engine (20, 120, 220). The heat engine (20, 120, 220) converts at least some of the heat transferred to the sCO 2 to mechanical energy to perform useful work onboard the aircraft.

摘要： Gas turbine engines (500, 600, 700, 800, 900) are described. The gas turbine engines (500, 600, 700, 800, 900) include a compressor section, a combustor section, a turbine section, and a nozzle (520, 620, 720, 820, 920), wherein the compressor section, the combustor section, the turbine section, and the nozzle define a core flow path that expels through the nozzle (520, 620, 720, 820, 920). A waste heat recovery system (502, 602, 702, 802, 902) is operably connected to the gas turbine engine (500, 600, 700, 800, 900), the waste heat recovery system (502, 602, 702, 802, 902) having a working fluid. An auxiliary cooling system (540, 640, 740, 840, 940) is configured to provide cooling to a working fluid of the waste heat recovery system (502, 602, 702, 802, 902).
