Abstract
Apparatus for equalizing the pressure between two compartments of an airplane in the event of sudden depressurization of one of the compartments, and including a closure panel disposed across an opening between the two compartments and functioning as either a blowout panel to be forced bodily from the opening upon development of an excessive differential pressure between the two compartments, or as a frangible panel which is shattered in response to attainment of the undesired differential pressure, to thus allow very open communication between the compartments preventing damage to a wall therebetween.
