Air conditioning for aircraft cabin has spaced air injection nozzles with mixing duct defined in moulding on cabin wall

摘要

The aircraft cabin ventilation has injectors (12) spaced along the cabin (10) to feed ambient air into the cabin. The injected air from each nozzle is mixed in a duct (24) which is conical to cause a circulating movement of the mixed air. The injectors are fed by a passage (11) in a strip moulding (9) attached to the wall of the cabin. The air duct can be defined between surfaces on the moulding and a decorative moulding on the cabin wall.
