Abstract
A system and method for protecting a lightweight pressure vessel capable of airborne and underwater use. The system includes an enclosure and a gas container that is capable of holding pressurized or liquefied gas in sufficient quantity to increase internal pressure of the pressure vessel, so that the internal pressure of the pressure vessel equals an external pressure of the pressure vessel. The system also includes a pressure relief device coupled to the enclosure. The pressure relief device is configured to release the pressurized or liquefied gas from the pressure vessel when the internal pressure exceeds the external pressure by a predetermined amount. The system also includes a gas supply mechanism coupled to the gas container, the gas supply mechanism being configured to allow gas from the gas container into order to increase the internal pressure of the pressure vessel until the internal pressure equals the external pressure.
