摘要:
A force transfer system includes a body and an article. The article includes a first portion forming a first lateral axis and a second portion forming a second lateral axis, the axes being offset. An intermediate member is disposed between the first portion and the second portion, and holds the second portion to the first portion. A stimulus received by the first portion causes a temporary alteration of the intermediate member from an initial condition, the alteration of the intermediate member thereby causing a change in a characteristic of the second portion. The intermediate member subsequently returns to the initial condition, thereby causing a change in a characteristic of the first portion, which is influenced by the change in the characteristic of the second portion. The change in the characteristic of the first and second portions prevents at least a portion of the stimulus from reaching the body.

A device for destroying a chemical agent is described. The device includes a self-contained, portable pressure vessel which is dimensioned to accommodate an artillery shell, and a heat-generating component within the pressure vessel. The heat-generating component is capable of providing a pyrolytic, exothermic reaction capable of destroying the chemical agent and artillery shell. A process for destroying a chemical agent which includes placing a chemical artillery shell within the pressure vessel, securing the pressure vessel closed, and igniting the heat-generating component inside the pressure vessel to generate a pyrolytic, exothermic reaction capable of destroying the chemical agent and artillery shell is also described.

A blast mitigation device having a first inner bag intended to house an explosive and further including a second outer bag to freely contain the first bag. Structural connections between the first and second bag are absent. The first and second bags each include a flexible tubular body made of textile material, provided with at least one openable mouth at one end of the flexible tubular body. The mouth is closable by a zip fastener or zipper and wherein at least the second bag includes a closure belt or strap arranged astride the openable mouth, such that in the assembled and use condition the zip fastener or zipper is wound inside a roll of an end portion of the body of the corresponding bag. The roll is kept in position by the at least one strap.

Methods and apparatus are provided for a blast attenuator having a container with an outer wall that defines a cavity in which a particulate media is disposed, and a stirring element disposed in and moveable relative to the container. At least a portion of the stirring element extends into the particulate media, wherein, in use, the particulate media provides resistance against movement of the stirring element relative to particulate media so as to attenuate the energy of a blast.

A shock attenuation device is used to reduce the effect of a blast shock by both disrupting the propagation of the shock and by spreading, deflecting, and/or redirecting the shock. The device includes multiple layers of different materials, having different shock transmission impedances, stacked in a direction in which the blast shock travels through the device. At least one of the layers includes a material that crumples in response to the shock, undergoing an inelastic deformation in response to the shock. Also, at least one of the layers includes a material that has a directional shock transmission impedance that provides different shock transmission impedance within different directions within the material. The directional shock transmission material may be oriented such that the preferred direction of shock transmission within the material is oriented away from the direction of in which the multiple layers of material are stacked.

A multi-tiered recoiling energy absorbing system has an upper impact surface that is exposed to percussive impact. At least one energy absorbing layer is positioned below or inside the upper impact surface. The energy absorbing layer includes one or more energy absorbing modules. At least some of the modules are provided with one or more energy absorbing units that extend from an upper platform. Several of the energy absorbing units are provided with a flexible wall that extends from the upper platform. A lateral reinforcement member secures the energy absorbing units to prevent them from splaying. The energy absorbing units at least partially absorb energy generated by an impacting object due to the flexible wall bending inwardly or outwardly and recoiling nondestructively after single or multiple impacts to its un-deflected configuration.

A fluid-jet-generating container for a flowable material includes a one-piece open-ended body having eight sides and eight corners. Each of the eight corners is defined by a V-notch such that the open-ended body may define a collapsed state when the eight sides are disposed in two parallel planes, and may define a configured state with the eight sides arranged to define an open-ended U-shaped trough. End caps are sealed to the opposing ends of the open-ended body in its configured state.

The present invention is directed to an impact absorption and detection system, including: one or more deflectable arch springs, having at least one leg with proximal and distal ends; and one or more bases, each of the proximal and distal ends attached to a base. Some embodiments may include: a plurality of arch spring assemblies, including: a deflectable arch spring having at least one leg with proximal and distal ends; one or more bases, each of the proximal and distal ends attached to a base; at least one sensor attached to the arch spring assembly; wherein the plurality of arch spring assemblies is configured in a chainmail arrangement and a base of one arch spring assembly is connected with a base of another arch spring assembly; a processor electrically connected to the sensors attached to the plurality of arch spring assemblies; and a data store in communication with the processor.
摘要:
The present invention relates to a new method for providing a destruction or detonation chamber (1, 9 and 27) intended for the destruction of ammunition products and other explosive products with an easily replaceable internal detonation and fragmentation protection (23-25). A particular characteristic of the detonation and fragmentation protection (23-25) according to the invention is that it comprises a large number of identical segments, which can take the form of a small number of inter-acting and mutually complementary variants, and which are all characterized in that they are relatively easy to handle and can be delivered to the interior of the destruction chamber (1, 9 and 27), where they are fitted in place through the closeable aperture (29), which in operation of the destruction chamber is used to charge the explosive material that is to be destroyed therein.
