METHOD AND DEVICE FOR ENVIRONMENTAL CONTROL OF AN AIRCRAFT SUPPLIED WITH BLEED AIR AT INTERMEDIATE PRESSURE

摘要

The invention relates to a method and a device for environmental control of cabin (11) aircraft. A compressor air intake (39) of the aircraft engine at a single intermediate pressure value is connected to an inlet of a compressor (48) of an intermediate turbocharger (47), an air outlet of this compressor (48) is connected to an inlet of an air cycle turbine engine (15), an output of the air cycle turbine engine is connected to the cabin (11), an inlet of a turbine (49) of the turbocharger (47) intermediate coupled to the compressor (48) receives air from the cabin (11), and the air pressure delivered to the air outlet of the compressor (48) of the turbocharger (47) intermediate is limited to a predetermined maximum value.
