ABSTRACT:
A pyrotechnically actuated dual air valve is hermetically sealed on both et and both outlet ports of static and dynamic air ducts until the dual air valve is actuated by a squib charge. A single piston, when activated by the squib charge, concomitantly opens all four hermetic seals to allow separate static and dynamic air flows through the dual air valve.
