ABSTRACT:
Sidewall vent valves for aircraft having one or more above deck compartments (29) designed to be convertible between passenger and cargo configurations is disclosed. The sidewall vent valves (52, 91 or 121) are located in the deck (27) of the aircraft between the skin (25) of the aircraft fuselage and the sidewall panels (37) of the convertible compartment. The sidewall vent valves (51, 92 or 121) are opened and closed by an electrical actuator that is common to several valves. In the open position holes in the deck are uncovered to allow air to flow from the convertible compartment (29) to the below deck cargo compartment (31) of the aircraft. In the closed position such air flow is prevented. The sidewall vent valves may be reciprocal (121) or rotary (51,91) and, preferably, include membranes (107, 127, 133) designed to "blowout" in the event of an explosive decompression in the below deck cargo compartment (31).
