A shaft (212; 312; 436; 536) is operably coupled to the turbine (214; 314; 428; 528) and configured to be rotationally driven by the turbine (214; 314; 428; 528). A fan (204; 304; 410; 510) is configured to generate thrust, the fan (204; 304; 410; 510) operably coupled to the shaft (212; 312; 436; 536) to be rotationally driven by the shaft (212; 312; 436; 536). A burner (206; 306; 418; 518) is configured to combust a fuel and air from the fan (204; 304; 410; 510) to generate a combusted gas and supply said combusted gas to the recovery heat exchanger (228; 328; 422; 522) of the closed loop-supercritical fluid system (216; 316; 426; 526) and out an exhaust nozzle (210; 310; 424; 524).",
