  • Patent number: 11519707
    Abstract: Embodiments employ venting features and damping components both inside and concentric to a fuzewell to improve munition fuze survivability. Damping components are selected based on their densities and stiffness properties. A shock damping liner with longitudinal grooves is affixed to an inner surface of the fuzewell and envelops the fuze. At least one shock damping collar constrains and attenuates shack experienced by the fuze. A shock damping ring is concentric about the outer surface of the fuzewell and attenuates shock, between the outermost munition system layer (the casing) and the fuzewell. Longitudinal vents in the fuzewell wall and radial apertures oriented transverse to the longitudinal vents are used for off-gassing. The venting and component orientation combination provides increased damping, resulting in impedance mismatches across multiple interface surfaces in the munition, which reduces shock vibrational pressures and stresses transferred to the fuze.

  • Patent number: 11519706
    Abstract: Embodiments are directed to direct impingement cook-off mitigation systems. As assembled, a munition fuzewell is torqued into the aft end of a munition. During a cook-off event, the expanding gases from the booster energetic will burn instead of detonating. The hot expanding booster gases are vented to the munition's main fill energetic causing the main fill energetic to burn concurrently with the booster energetic. The combined expanding gases from both the booster and main fill energetics are then vented through longitudinal vents.

  • Patent number: 11454482
    Abstract: An explosive detonating system comprises connectable components to connect/disconnect a pathway that ignites an explosion. A firing actuator activates primers (percussion caps). An adapter connects the firing actuator to shock tube and channels the ignition force into the shock tube. A cap box houses blasting caps coupled to the end of the shock tube. A priming well is coupled to the cap box/blasting caps and the detonating cord. When the firing actuator is initiated, the percussion caps ignite, sending an explosive wave into the adapter, which channels the wave into the shock tube and ignites the shock tube. The explosive wave travels through the shock tube and activates the blasting caps, which activate the detonating cord in the priming well. The explosive is placed in a location to provide a desired explosive effect. For example, the system may be employed as a system to breach structures or other applications.

  • Patent number: 11428512
    Abstract: A hollow spherical projectile is constructed from a plurality of curved structural segments and has a plurality of openings. The projectile can be fired by a conventional paintball marker with a high degree of ballistic accuracy. The projectile is reusable and is fabricated from a flexible and resilient material. The outer surface of the projectile exhibits low friction, achieved by the material itself or by having a low friction coating applied. The projectile possess and transmits less kinetic energy than a conventional paintball and therefore inflicts less pain and damage upon impact. Fabrication can be accomplished by 3D printing, or molding as a single seamless piece, or as a plurality of pieces which are then assembled.

  • Patent number: 11402187
    Abstract: A lightweight projectile having an integrated metal band positioned around the exterior of the polymer base of the projectile. The metal band may be a driving band that protrudes from the polymer base to minimize the contact between the polymer base and the rifling to reduce friction between the barrel and the projectile as the projectile is fired. The lightweight projectile may be propelled with less propellant force than conventional projectiles of the same caliber while still retaining the ballistic advantages of a spin stabilized projectile.
