Abstract: Disclosed are a protection equipment, system and method for the destruction of explosives. The protection equipment for the destruction of explosives includes four modules: an inner fence, an outer fence, an anti-leakage fence and a top cover. The modular equipment takes an overall nonmetal flexible composite structure, and the individual modules are light in weight and convenient to operate. It can be operated by two persons or a single person. A protective effect can be achieved during destruction of explosives by using the protection equipment, and even if the explosives explode during destruction, it will not cause injury to surrounding personnel. A protection system for explosive destruction based on the protection equipment can be used to destroy unexploded bomb or explosives under protective conditions, thereby achieving rapid emergency disposal without making contact with the explosives.

Abstract: Provided herein are projectiles for use in a propellant driven disrupter device, and associated methods, to neutralize an explosive target. The projectile may comprise a friction reducing container at least partially filled with one or more fluids, fluid mixtures, particles, and other components to provide one or more desired fluid properties to achieve a desired one or more jet parameters upon target impact. The fluid(s) in the container are referred to as highly efficient energy transfer (HEET) fluids do to the improved fluid jet action on target compared to conventional water projectiles. The projectiles and disruptor can be more precisely individually tailored to the target, thereby increasing the likelihood of successful disablement and decreasing the likelihood of inadvertent and uncontrolled explosion.

Abstract: An effector having an extendible range and a method for extending the range of an effector includes using an axially translatable center body that is movable from a stowed position, in which the center body is stowed in an outer body of the effector, to a deployed position in which the center body extends out of the outer body to extend the axial length of the effector. The effector includes a ramjet assembly and the subsystems of the effector are contained in the center body. The movement of the center body exposes radially positioned ramjet fuel in the outer body, such that the air entering the ramjet inlet may be heated by combusting the air with the fuel for additional fuel and propulsion of the effector.

Abstract: A piston/rocket projectile for use within a launcher system having a barrel and method of firing such are presented herein. The projectile comprises a projectile body having a combustion chamber for propellant, a piston moveable to extend out a base of the projectile as a result of ignition of propellant in the combustion chamber, and vents for expulsion of combustion products from the ignition of propellant out of the projectile base after initial movement of the piston. A casing is secured to the base of the projectile body, enclosing the piston and vents prior to the ignition of propellant, and a separable joint is disposed between the casing and the base of the projectile body. Upon ignition of propellant in the combustion chamber, the projectile piston is forced down and the separable joint is caused to separate, leaving the casing in the barrel.

Abstract: This disclosure describes a system, and apparatus for securely mounting a firearm, while maintaining to ability to load, unload, and draw the firearm from the mount with a single hand. This is accomplished using a mount that is customized to conform to a specific model of firearm, ensuring a snug fit of the firearm within the mount. Magnetic retention secures the firearm in place in the mount. Modern, magazine fed handguns can be loaded and unloaded simply by moving the slide. Cycling the slide causes it to extract a round from the chamber (if a round is present) when the slide traverses rearward relative to the receiver. A new round is loaded from the magazine when the slide traverses forward relative to the receiver (if a loaded magazine is inserted).
