  • Patent number: 8468946
    Abstract: A modified 40 mm grenade round designed to breach doors without throwing a significant amount of shrapnel into a building's interior or back toward the shooter. The modified round includes a forward extension on the ogive. The extension is rigidly connected to a thrust column which transmits an impact load directly from the ogive's nose cap to the striker on the fuse assembly. This configuration detonates the explosive charge within the projectile while the explosive is still well outside the door. This early detonation throws a pressure wave again the door's exterior, forcing the door inward.

  • Patent number: 8413586
    Abstract: A modified 40 mm grenade round designed to breach doors without throwing a substantial amount of shrapnel into a building's interior. The modified round includes a standoff device located on its forward end. The standoff device detonates the explosive charge within the projectile before the nose of the projectile actually strikes the target. This early detonation throws a pressure wave again the door's exterior, forcing the door inward. Shrapnel produced by the detonation remains primarily outside the door. Thus, the modified projectile is able to blow open a door without throwing a significant amount of shrapnel into a building's interior.

  • Patent number: 8387538
    Abstract: Some embodiments pertain to a projectile that includes a propellant and a casing that encloses the propellant such that the casing acts as a reaction chamber during flight of the projectile. The casing includes a plurality of flechettes. When the projectile strikes (or is near) a target, a large internal sheer pressure forms within the casing. This sheer pressure causes the flechettes to sheer apart at the thinnest sections of the casing. Once the thin sections of the casing are sheered apart, the flechettes will be unconstrained such that the flechettes take individual flight paths.

  • Patent number: 8297187
    Abstract: A marking projectile comprises separate compartments that break during launch due to rotation of the projectile as it leaves the barrel of a weapon. Metal pellets contained within the compartments are pressed outward and pierce the compartment walls. This allows for mixing of chemical materials contained within the compartments, so that the materials substantially react by the time the projectile strikes a target. The chemical materials may be a pair of chemi-luminescent components, or components that create heat for thermal marking.

  • Patent number: 7802520
    Abstract: A modified cartridge assembly including a projectile having a gas generator proximate its aft end. The projectile includes an aft closure having a cavity filled with gas generating material. The gas generating material is ignited around the time the projectile exits the weapon's muzzle. The gas generating material then burns while the projectile is in flight, spewing pressurized gas into the wake region immediately behind the projectile. The pressurized gas reduces the projectile's base drag.

  • Patent number: 7793591
    Abstract: A modified projectile round which is configured to function with a propellant cartridge such as described in U.S. Pat. No. 7,004,074. The projectile assembly uses a High-Low gas pressure cartridge to launch the projectile. When the high pressure cartridge is ignited, hot propellant gases rupture a burst cup and shoot propellant gases toward the aft end of the projectile. The hot propellant gases impinge against a delay carrier located in the aft end of the projectile. The contents of the delay carrier are thereby ignited. The delay carrier includes one or more delay columns ultimately terminating in an igniter charge. The delay columns burn as the projectile is in flight. A specified amount of time later, the igniter charge ignites an ignitable payload—such as a marker flare candle.

  • Patent number: 7493859
    Abstract: A method for achieving zero, or near zero, latency timed pyrotechnic events by utilizing distributed processing is presented. A list of timed events may be used to synchronize a pyrotechnic firing sequence with music or other external events. This list is distributed over a series of embedded microprocessors. Each microprocessor is then synchronized to a master controller clock, and enabled such that each processor may then fire independently as required by the master list. This distributed process removes the split-second timing requirement from the main controller enabling the achievement of zero latency and providing significantly more timing events to be processed simultaneously while alleviating problems such as wireless radio interference delays. Each module is capable of forwarding information to other modules, which may be a position that prevents wireless communication directly with the master controller.

    Abstract: The grenade is a multi-purpose munition which can be used as a distraction device, like a flash bang grenade, and can be equipped with chemical agent powder for added capabilities. The grenade is also a sting ball grenade and is a less-lethal form of weapon, designed to reduce fatalities in civilians located in conflict areas. The munition is constructed to be low lethality, and capable of being launched from military and law enforcement 37 mm and 40 mm grenade launchers presently in use today. It is designed to be used in multiple roles when lethal projectiles are not a viable or preferred option, such as hostage situations, riots, room and building clearing operations, narcotics interdictions, distraction and diversionary purposes, and as a method of introducing a chemical agent into a small area from a distance. The grenade can be employed from distances over 400 yards, extending the range of the present art, which is 30 yards.

An aerodynamic shell is sized for delivery to a target by hand or mechanical means, including a first explosive charge is in a forward portion and a release device enclosing a second explosive charge is disposed in a shell rear portion. The release device includes a segmented cone positioned behind the first explosive charge, and a segmented cylindrical unit extending rearwards to enclose the second explosive charge within the shell during flight. Upon impact with the target, the first explosive charge detonates and directs high pressure gases against the target and deflection of gases rearwards against the segmented cone. The segmented cone and cylindrical unit are forced to separate and pivot outwards thereby releasing the second explosive charge for delayed delivery and detonation against the target leading to breach and destruction.

  • Patent number: 6889612
    Abstract: A long-distance blast banger including a cartridge loaded with a blast banger made up from plastic material. The blast banger encompasses a sound explosives cup and a delay cup. The sound explosives cup is loaded with a sound explosives agent having components including perchloryl potassium, magnesium powder and aluminum powder. A sufficient sound value is acquired through appropriate compacting of the sound explosives cup, and therefrom realizes uniform shattering of the cup into small fragments that are insufficient to cause injury. Furthermore, at least two helical grooves extending from a bottom to a top of the cartridge are defined on an inner wall thereof, and ear attachments are configured on a base of an outer wall of the blast banger so as to correspond with the helical grooves, thereby engendering a spinning stability effect during flight time of the blast banger, reducing wind resistance, and thus increasing flight range.

  • Patent number: 5168123
    Abstract: The invention relates to the chemical initiation of detonation of a fuel-in-air (FAE) cloud such as might be used in a minefield breaching system. A component of the system is adapted to carry fuel to the breaching site and is also adapted to carry a compatible chemical, either gaseous or liquid. Upon detonation of a suitable explosive within the component the fuel is dispersed outwardly to form the cloud and the chemical is jetted outwardly into the cloud in a turbulent manner. A chemical reaction between the chemical initiator and the fuel-air mixture leads almost instantaneously to an explosive shock wave that propagates through the cloud causing detonation thereof. Such detonation neutralizes the minefield along a desired path. With the invention it is not necessary to utilize secondary charges and hence a more efficient and reliable breaching system is achieved.
