ABSTRACT:
An air return grille for an aircraft mounted below the passenger cabin sidewall comprises openings to allow return airflow from the air conditioning system. In a preferred embodiment, the grille openings are covered by a single thin baffle 32 with cutouts within its periphery that slip over and are held in place by fasteners on the molded grille 28. The thin baffle 32 is affixed to the molded grille 28 along one or more edges on the grille. All other thin baffle 32 attachments allow for the baffle to be disengaged upon the onset of a rapid decompression. During normal operation, the thin baffle 32 restricts flow through a small opening in the grille. During a sudden/rapid decompression of the cargo compartment/lower lobe, the baffle is dislodged from the fasteners and forced into a position parallel to the airstream. This allows the airflow to pass through all of the molded grille 28 openings in order to achieve rapid pressure equalization.
