摘要： A turbine engine assembly (20) includes a tap (92) is at a location upstream of the combustor section (26) where a bleed airflow (64) is drawn. The bleed air is pressurized in an auxiliary compressor section (72), heated in an exhaust heat exchanger (82) and expanded through a power turbine (74) that is coupled to drive the auxiliary compressor section (72).

摘要： A gas turbine engine assembly (20) including a tap (66) that is at a location up stream of the combustor section (26) for drawing a bleed airflow(68) . An exhaust heat exchanger (70) is configured to transfer thermal energy from the exhaust gas flow (64) into the bleed airflow (68) and communicate the heated bleed airflow (72) into the turbine section (28) where it is expanded to drive the turbine section (28).

摘要： A gas turbine engine assembly includes a core engine (20) that includes a core flow path where a core airflow (25) is compressed in a compressor section (24), communicated to a combustor section (56), mixed with fuel and ignited to generate an exhaust gas flow (74, 75) that is expanded through a turbine section (28). The turbine section (28) is coupled to drive the compressor section (24) through an engine drive shaft (88). A tap (64) is at a location up stream of the combustor section (56) for drawing a bleed airflow (66, 65). A bleed air heat exchanger (72) places the bleed airflow (66, 65) in thermal communication with an auxiliary flow (68) for heating the bleed airflow (66, 65). An exhaust heat exchanger (76) is configured to transfer thermal energy from the exhaust gas flow (75) into the bleed airflow (66, 65).
