ABSTRACT:
A rocket engine protection system for a recoverable rocket booster which is arranged to land in a salt water body for recovery. The system includes an inflatable water impermeable elastomeric bladder that may be fabricated of a silicone impregnated woven Kevlar material and which is stowed in a deflated condition on a rotatable arm that is journalled to the lower portion of the nozzle of a liquid rocket booster. The deflated bladder and the rotatable arm are protected by a pod cover that is hinged to the outer portion on the nozzle. During the controlled descent of the liquid rocket booster by parachute for landing in a salt water body the pod cover is released and opened upwardly by a gas cylinder actuator. The rotatable arm which is biased by a torsion spring is then permitted to rotate around to position the deflated bladder in a deployed position within the interior of the lower portion of the nozzle. The bladder is then inflated to form a plug within the nozzle. A gasket is provided on the outer perimeter of the inflated plug to assist in sealing the plug against entry of sea water into the
