FIELD: air conditioning.
SUBSTANCE: invention relates to an atmospheric aviation air conditioning system (ACS) for aircraft and concerns an external air supercharger for an aircraft ACS. The air blower is based on a gas-dynamic fan propulsion system, driven from the fan drive shaft, made as an impeller circuit, with an external air receiving device in the form of a hole in the fan fairing. Moreover, internal surfaces are formed inside the cylindrical fan hub, forming longitudinal channels for the passage of air coming from the receiving device. Blades are attached to the outer side of the hub at an angle to the fan axis, made with a longitudinal cavity through passage, forming holes that provide communication between the cavity of each blade and the channels in the cylindrical fan hub.
EFFECT: simplification of the design of the system for supplying ACS with high-pressure air while achieving reduced power consumption of the ACS and its loss, increasing the reliability of the ACS.
