摘要:
An inflatable trajectory altering and blast energy absorption system has a plenum with walls that are spaced apart from one another when the plenum is inflated. Flexible members, dispersed in the plenum and coupled thereto, are placed in tension when the plenum is inflated. Means for altering the trajectory of a projectile entering said plenum are dispersed within the plenum.

A system and method are provided for improving vehicle safety in a crash situation for a vehicle having mountable vehicle components. A plurality of pyrotechnic bolts are used to mechanically couple at least a portion of the vehicle components to the vehicle. A force measuring device measures forces experienced by the vehicle during a crash and produces a signal indicative thereof. This signal is compared with a threshold. An activation signal is generated when the threshold is attained. Failure of the pyrotechnic bolts is then initiated in accordance with a prescribed plan.

A detonation arrestor cuts the detonating cord of a dud line charge to prevent the pressure wave from a nearby explosion from sympathetically detonating the dud line charge. A housing of the detonation arrestor has a transverse passageway to receive the detonating cord of the dud line charge and an axial bore intersecting the passageway. A cutter piston having a cutter blade is disposed in the bore and is sized to permit axial displacement by a shallow dish-shaped diaphragm spring. The diaphragm spring has its center adjacent to one end of the cutter piston and laterally extends from the bore to be secured to the housing along its round periphery in a sealed relationship. The diaphragm spring is formed in the configuration of a Belleville spring from a spring material providing strength, rigidity, and spring modulus to snap to an extended position when displaced to a position past an over center position by an impinging pressure wave. When the diaphragm spring is displaced by the impinging pressure wave to snap to the extended position, it axially displaces the cutter piston in the bore to cut the detonating cord with the cutter blade and arrest detonation of interconnected ordnance.

A munition is provided for deploying a molten payload within a target. A plurality of holes are formed in the munition's projectile body about the circumference thereof. A seal closes off each hole. A firing mechanism is mounted in the munition's nose cone and is capable of generating energy of initiation upon deformation of the nose cone. A first burnable material is housed in the projectile body and is coupled to the firing mechanism to receive the energy of initiation. The first burnable material extends in a tree-like fashion along a plurality of connected paths in the projectile body with each of the connected paths terminating at one of the seals. A second burnable material fills the voids in the projectile body surrounding the first burnable material. The first burnable material has a lower threshold of combustion than the second burnable material while the second burnable material burns hotter than the first burnable material.

An underwater noise generator has a submerged housing containing a receiver section responsive to remotely originating acoustic signals or magneto-inductive signals in the ELF to VLF range. The submerged housing contains a composition that reacts with water to produce gas. The signals initiate an explosive squib that blows a lid off the housing and penetrates a wall that covers the composition. Water floods into the housing and onto the composition which produces gas that creates bubbles. The bubbles are buoyed from the noise generator to the surface and, in so doing, they produce noise. Underwater noise generators can be used singularly, in multiples, or in various patterns as needed to conceal activities or otherwise deceive remote listeners. Appropriately coded magneto-inductive control signals in the ELF to VLF range are transmitted from a variety of remote sources through the sea, air, vegetation, and sediment or any combination of these conditions to activate the underwater noise generators.

A wide-area mine clearance device having a flexible hose that is extended rough a suspected area of mines. An explosive composition slurry is pumped into and through the extended hose. A detonator is attached to the hose, after which the explosive composition in the hose may be detonated.
摘要:
An intrusion detector has buried sensor modules arranged along a perimetero sense seismic vibrations caused by intrusions within the area defined by the perimeter. The sensor modules transmit data representative of the intrusions via magneto-inductive signals in the ELF to VLF range through ground, air, and/or water to at least one buried relay module within the area. The relay modules transmit RF signals representative of the intrusion data via a camouflaged RF antenna to mobil or fixed stations for appropriate action. Transmission of magneto-inductive signals in the ELF to VLF range is clandestine and reliable, and locations of buried sensor modules and relay modules are not revealed to intruders to reduce the possibility of evasion or tampering. The sensor modules may have sensor elements sensitive to humans, vehicles, and low flying aircraft to give enforcement officers the opportunity to better utilize their resources where the intrusions are occurring. In addition, this system could be placed along many well-used passageways, such as highways, roads, trails, air corridors, etc. to gather information regarding use of facilities and resources to help governmental officials and planners make intelligent decisions.

A vehicle is provided for drone stowage and transport as a means to extend the range of smaller drones and unmanned underwater vehicles. The transport vehicle is launched from a mother ship and provides for moving drones and underwater unmanned vehicles to desired launch and recovery points. The vehicle is based on current hovercraft vehicles and is adapted for stowage of drones while remaining compatible with existing mother ships. The vehicle includes foldable deck sections, which can be extended to provide launching and landing runways for flying drones. Lifts and ramps are incorporated for loading, launching and recovering flying drones, floating drone vessels and underwater unmanned vehicle drones.

A variable shock wave bio-oil extraction system and method utilizes shock waves to separate oil, water, and biomass from feedstock in a single step. In one embodiment, at least one pair of opposing transducer arrays are arranged in a shock wave extraction housing and collectively powered by a pulse controller to create controllable shearing planes and/or shearing regions and/or shock stem zones to interact upon a flow path of feedstock as the feedstock travels through the shock wave housing.
摘要:
An IR radiating decoy for an IR seeking anti-ship missile (ASM) includes a propulsion section, safe and arming section, gas generator section, fuel tank section, and flight stabilization section to ignite and continuously maintain an IR plume for decoying the ASM away from the targeted ship. The IR radiating decoy ignites the IR plume immediately when the decoy reaches a safe separation distance from the targeted ship. The IR plume continues to be emitted as the decoy flies away, as it lands on the water, and while it floats upon the water until all the fuel is used from the fuel tank. The fuel can be changed to change the signature of the IR plume so that different ASM missiles can be drawn away from the ship.
