ABSTRACT:
A grille for an aircraft mounted on the cabin sidewall includes apertures to allow return airflow from the air conditioning system. In a preferred embodiment, the grille apertures are covered by resilient baffles which are resiliently folded into semicircular configurations and held in place between adjacent ribs of the grille by the force exerted by the folded baffles. One end of each baffle is affixed to upper and lower rods of the grille, while an opposite end of each baffle is releasably inserted over the rods. During a sudden decompression of the cargo compartment, the releasable ends of the baffles are dislodged from the rods and unbend into a flat shape in a manner parallel to the airstream. This permits rapid pressure equalization between the cargo and passenger compartments. The tops and bottoms of the baffles when in the folded closed position are open thereby permitting sufficient airflow therethrough to achieve rapid pressure equalization in the event of reverse decompression when the passenger cabin is rapidly decompressed.
