  • Patent number: 9739583
    Abstract: A fragmentation munition has a fragmentation canister containing preformed fragments, and an explosive cartridge that fits into a central hole in the fragmentation canister. The explosive cartridge includes an outer shell, and an explosive within the outer shell. The munition may be configured to precisely deliver fragments to a relatively small area, such as an area that is a few meters in radius. Toward that end the explosive may be configured primarily to rupture the housing and secondarily to spread fragments over a limited area. The main kinetic energy of the fragments is from the acceleration they gain as part of the munition falls from a launcher, such as a carrier aircraft. The dispersed fragments may have a similar downward velocity after controlled dispersal by the explosive, allowing them considerable kinetic energy (considerable penetrating power), but with a precisely controlled dispersal area.

  • Patent number: 8312813
    Abstract: A deployable fairing is driven off of high-pressure gun gases to reduce aerodynamic drag and extend the range of the artillery shell. An artillery shell is provided with a fabric fairing and a piston attached thereto in a rear section of the shell in a stowed state and a chamber. During launch high-pressure gun gasses are captured and stored in the chamber. Once the shell clears the end of the artillery tube, the pressure aft of the shell drops from the high pressure inside the tube to atmospheric pressure outside the tube. The high pressure gun gasses stored in the chamber act over the top surface of the piston to drive the piston aft against the much lower pressure behind the projectile to deploy the fabric fairing attached thereto to reduce the base area of the projectile creating or extending the boat-tail of the shell, hence reduce aerodynamic drag. The aft driven piston engages a locking mechanism that locks the piston in a deployed position.

  • Publication number: 20120180686
    Abstract: A frangible projectile, and weapon cartridge containing same, is provided, in which the frangible projectile is comprised of a hollow outer body composed of, for example, a plastic or polymeric material, configured to provide a payload material. Preferably, the hollow outer body has an interior surface having a divider formed or disposed therein, for controlling the movement of the payload material after firing. The hollow outer body of the frangible projectile, upon impact, rapidly fragments upon impact into relatively harmless pieces, and releases/mixes the payload material. However, the payload material may be chosen to provide sufficient mass, and accordingly sufficient kinetic energy, to provide desired target effects, such as powder metals. Alternatively, payload materials, such as reactive chemical components, marking agents, chemiluminescent compositions, incapacitants, multi component reactive compositions, etc., preferably contained within one or more payload containers, are provided.

  • Patent number: 8119956
    Abstract: A multi-stage hyper-velocity kinetic energy missile (HVKEM) uses a ‘missile in a missile’ architecture in which the HVKEM includes a 1st stage flight missile and a 2nd stage kill missile that includes a KE-rod penetrator. The flight missile cruises at a relatively low velocity (less than Mach 1.5, typically less than Mach 1) to conserve propellant (weight) and to allow for effective guidance and maneuvering until the missile is in close proximity to the target. When the missile is within the lethal range of the KE-rod penetrator, the kill missile separates and boosts to a much higher velocity (greater than Mach 3, typically greater than Mach 5) and flies unguided to impact the target in less than a second. Waiting to boost the KE-rod until “the last second” reduces the total propellant (weight) needed to deliver the KE-rod on target and simplifies the guidance.
