ABSTRACT:
A check valve is secured to the base of an air deployable ram-air inflata bag attached in the crown of a parachute or decelerator. Upon descent, air is forced through an orifice in the valve thereby opening a flapper and inflating the bag while decelerating the downward velocity of a sonobuoy attached to the decelerator. Upon water entry, water flows into the bag and expands a sponge positioned in the valve thereby forcing the flapper against the orifice and preventing the escape of trapped air from the bag during low frequency vertical oscillation in a static floating position.
