    摘要: An environmental control system (ECS) pack is provided including a primary heat exchanger, a secondary heat exchanger, and an air cycle machine. The air cycle machine includes a compressor and a turbine. The compressor is fluidly coupled to an outlet of the primary heat exchanger and to an inlet of the secondary heat exchanger. The outlet of the secondary heat exchanger is fluidly coupled to the turbine. A first conduit connects the outlet of the primary heat exchanger and the inlet of the secondary heat exchanger. The first conduit includes a first valve. A second conduit connects the outlet of the secondary heat exchanger to an air load. The second conduit includes a second valve.

    摘要: A structure for anti-adhesion of high-temperature air according to the present invention includes: a high-temperature air duct that is provided in an accessory of an aircraft and allows high-temperature air likely to be higher than a specified temperature to flow through the high-temperature air duct; an exhaust port that discharges a flow of the high-temperature air led through the high-temperature air duct, to an outside of the airframe; and a low-temperature air supplying part that supplies a flow of low-temperature air lower in temperature than the high-temperature air discharged to the outside of the airframe, to an airframe surface. The low-temperature air supplying part is configured to form an air layer made of a flow of low-temperature air between the high-temperature air that is bent toward the airframe surface in flight of the aircraft, and the an airframe surface.

    摘要: An environmental control system including a turbomachine assembly having a shaft, motor, turbine and compressor, the compressor outputting a compressed air stream, a first valve that splits the compressed air stream into first and second compressed air streams, a heat exchanger to cool the first compressed air stream and output a cooled air stream, a second valve positioned to receive the cooled air stream and split the cooled air stream into first and second cooled air streams, wherein the first cooled stream is expanded in the turbine to produce an expanded air stream that is combined with the second compressed air stream and the second cooled air stream to provide a combined air stream having a temperature and a flow rate, and a controller that communicates control signals to the compressor, motor and first and second valves to control the temperature and flow rate of the combined air stream.
