An overpressure protection system (30) for a magazine (10) for storing explosive materials. The magazine (10) comprises a wall (12) which defines an internal chamber (14) for housing the explosive materials, with a first aperture (20) defined in the wall (12). The overpressure protection system (30) is configured to close the first aperture (20). The system (30) comprises a burst disc diaphragm (32) for covering the first aperture (20), and a protective cover (34) for locating outside of the chamber (14) and over the burst disc diaphragm (32). The protective cover (34) is spaced apart from the burst disc diaphragm (32) to form a cavity (38) with an opening (36) for venting fluid from the cavity (38).

Proposed is a cover structure with a double cover structure and a shooting case of munition having the same. The cover structure with a double cover structure includes: a shooting case main body having an inner space with an open upper side; a cover member seated on the open upper side of the shooting case main body to seal the open upper side; and a cover fixing member coupled to the shooting case main body to fix a position of the cover member, so that the position of the cover member is strongly fixed while simplifying a structure by the double cover structure to increase an internal pressure of the shooting case, thereby increasing a range of munition and maintaining performance of munition.

A mitigation control system, for performing an active hazard mitigation method, is arranged in an environment containing an energetic material and includes an abnormal temperature sensor for detecting an abnormal temperature of the environment, a power source that is mechanically actuated by the abnormal temperature sensor when the abnormal temperature exceeds a predetermined abnormal temperature threshold, a mitigation controller that is actuated by the power source, and a plurality of local temperature sensors that are communicatively coupled to the mitigation controller and are arranged for detecting critical temperatures in specific regions of the environment. The mitigation controller executes a mitigation action when one of the critical temperatures exceeds a predetermined critical temperature threshold for the corresponding specific region.

Embodiments are directed to direct impingement cook-off mitigation systems. As assembled, a munition fuzewell is torqued into the aft end of a munition. During a cook-off event, the expanding gases from the booster energetic will burn instead of detonating. The hot expanding booster gases are vented to the munition's main fill energetic causing the main fill energetic to burn concurrently with the booster energetic. The combined expanding gases from both the booster and main fill energetics are then vented through longitudinal vents.

A drum for transporting and/or storing batteries, the drum having an internal storage space having a volume, and the drum being provided with a lid to close off the storage space The lid is provided with one or more openings for venting gas from the storage space to the atmosphere. One or more openings have a total surface area of at least 1.0 square centimeter per liter volume of the storage space. On an outside of the lid is at least one sheet of foil which covers a first group of two or more of said openings, in which the sheet of foil is connected to the lid completely around the first group of openings.

Methods and systems are provided for a firearms suppressor adapted with blowout panels. In one example, the blowout panels may be configured to have a lower tolerance for pressure than the materials from which outer components of the suppressor are formed. During over pressure events of the suppressor, the blowout panels may rupture, thereby dissipating pressure in the suppressor.

The disclosed embodiments are directed to enhancing insensitive munitions performance. Some of the embodiments employ an outgassing pad having unique geometrical configurations, compositions, and positioning. Other embodiments rely on using thermally-releasable components to foster billet expulsion. Additional embodiments combine both aspects into entire cook-off mitigation systems for insensitive munitions improvements.
