Ventilation system, air blowing and extraction circuits of such a system, as well as an aircraft avionics bay

摘要

A ventilation system for an avionics bay has two strut assemblies for stiffening the floor of the cockpit, each strut assembly being arranged symmetrically regarding to the central plane of the aircraft, and means of distribution of the blowing air in the cabinets of the bay from the strut assemblies. The extraction circuit includes exhaust ducts integrated in the cabinets and couples together by tight inter-cabinets junctions in an overall configuration of maximized compactness.

主权项

1. A ventilation system for an electronic bay being integrated into an aircraft, comprising at least one cabinet, the system comprising:
a blowing circuit; and an extraction circuit; wherein one of the blowing and extraction circuits comprises:
at least one strut assembly integrated into an aircraft floor, said at least one strut assembly comprising a first transversal wall, a second transversal wall, and a first longitudinal wall extending from the first transversal wall to the second transversal wall; andair distribution means, between the at least one cabinet and the at least one strut assembly, the air distribution means comprising at least one orifice defined within at least one of the first and second transversal walls, and the first longitudinal wall; andwherein the other of the blowing and extraction circuits comprises at least one air transmission conduct integrated into the at least one cabinet,wherein the blowing circuit comprises said at least one strut assembly integrated into the aircraft floor and said air distribution means, andwherein the extraction circuit comprises said at least one air transmission conduct.
