摘要： A cryogenic cooling system (2200) for an aircraft (800) includes a first air cycle machine (2201), a second air cycle machine (2220), and a means for collecting liquid air. The first air cycle machine (2201) is operable to output a cooling air stream (2210) based on a first air source (2204). The second air cycle machine (2220) is operable to output a chilled air stream (2223) at a cryogenic temperature based on a second air source (2221) cooled by the cooling air stream (2210) of the first air cycle machine (2201). An output of the second air cycle machine (2220) is provided to the means for collecting liquid air.

摘要： An after-fan system for an engine (20) may comprise an after-fan turbine (122) an electrical generator (150) operationally coupled to the after-fan turbine (122), and an electric motor (152) electrically coupled to the electrical generator (150). The electrical generator (150) may be configured to generate an electrical current in response to rotation of the after-fan turbine (122). The electric motor (152) may be configured to generate torque.
