  • Patent number: 7304164
    Abstract: 1-Methyl-2,4,5-Trinitroimidazole is synthesized starting from 4-nitroimidazole using stepwise nitration method and further methylation using Dimethylsulphate. It is relatively insensitive to impact and its thermal stability is excellent. The calculated detonation properties indicate that its performance is about 30% better than TATB. It can be prepared easily, with reasonable yield, starting from commercially available Imidazole. Results from impact sensitivity, friction sensitivity, time-to-explosion temperature and vacuum stability tests indicate that it is less sensitive than both RDX and HMX. The good oxygen balance and measured heat of formation data of this material indicate that its propellant performance should be good.

  • Patent number: 7089863
    Abstract: A non-lethal cartridge having sufficient discharge energy for use, without modification, in conventional firearms. When used with a firearm with a rifled barrel, the cartridge comprises a non-lethal projectile having a grooved outer surface and a dense powder ballast. Upon discharge, the dense powder ballast is dispersed. When used with a smooth bore firearm, the cartridge also comprises a cylindrical casing having rifling grooves on the inner surface thereof. These grooves will impose a spin on a projectile fired from the cartridge casing. The dense powder ballast will provide sufficient initial inertial mass to permit proper functioning of the firearm, but disperses and dissipates a portion of the discharge energy, simulating the recoil impulse and permitting the non-lethal projectile to simulate the trajectory of standard ammunition.

  • Patent number: 7061604
    Abstract: A structural member of a mortar projectile is inspected. The structural member is a composite structure having a thermoplastic matrix with a filler of steel balls. The composite structure has a central cavity into which is placed a strobe light. Surrounding the composite structure is a detection arrangement having a detection medium of photographic film. When the strobe light is activated the film is exposed and developed to obtain an image indicative of the distribution of the steel balls in the matrix. The image is analyzed to determine if the structural member is acceptable.

  • Patent number: 7007607
    Abstract: A hinged explosively formed projectile warhead system eliminates exposure of soldiers to harm in wall breaching operations by providing a lethal mechanism that can be deployed at safe distances, simultaneously breaching a man-sized hole and removing one or more rows of rebar in reinforced concrete structures or barriers. The warhead system employs both a missile system and explosively formed projectile warhead technology delivered to the target from a tube launched platform. A set of warhead arms is attached to the aft end of a missile body by means of a set of hinges. The warhead arms are initially folded against the missile body. After launch of the warhead system, the warhead arms fold away from the missile body. The angle at which the warhead arms are folded from the missile body determines the area of a hole breached by the warhead system in a reinforced concrete target.

  • Patent number: 7004424
    Abstract: A mechanism to alter the flight path of a projectile after launch. A plurality of fins are disposed around the projectile and are held in place by one or more caging wires, depending on fin design. In one embodiment, auxiliary fins are connected to adjacent main fins which are held in a stowed position. When released, the fins deploy and present a continuous surface to the airstream for maximum braking action. In another embodiment, each fin is divided into fin segments which are individually deployable to alter the spin or course of the projectile by deflection. Additionally, all of the fins may be deployed to provide a braking action. All of the fins are tied together to distribute and reduce encountered loads when deployed.

  • Patent number: 6868791
    Abstract: A single stage kinetic energy warhead using multiple explosively formed projectile (EFP) liners in a stacked configuration is capable of breaching intermediate barriers and defeating a primary target. The main explosive charge is detonated and the subsequent shockwave causes the front liner to be shaped to breach an intermediate barrier. The main liner is formed into a more compact rod-shaped projectile designed to defeat the main target. The weight and volume of the stacked liner configuration of the present system is significantly lower than the weight and volume of current systems. The present system requires a single firing explosive train eliminating developmental cost and complex fusing. The present system utilizes explosive detonation, simplifying the delivery of a projectile and eliminating the need for a missile delivery system. The size and simplicity of the present system allows for portability and use by an individual.
