  • Patent number: 8205537
    Abstract: An interceptor projectile includes a deployable net that deploys during flight and wraps around an incoming projectile, such as a rocket propelled grenade (RPG). The net is initially in a tubular body of the interceptor projectile. A propellant is used to deploy the net from the body. Even after deployment the net remains attached to the body by an elastic tether. The engagement of the net with the incoming projectile disables the incoming projectile, with the momentum imparted by the interceptor projectile sending the incoming projectile off course. This successfully defends a target against the incoming projectile. Through the tether, substantially all of the parts of the interceptor projectile may be mechanically linked together even after deployment of the net. This mechanical linking provides more momentum for impacting the interceptor projectile, which may facilitate diverting the incoming projectile.

  • Patent number: 7640839
    Abstract: A cartridge for propelling a pair of wire-tethered contact darts for disabling a remote target with an electrical discharge. The cartridge comprises two bores each having one wire-tethered dart in front of an electrically activated pyrotechnic. A cartridge contains two separated straight bores, which each launch a single dart assemblage with a single primer of standard manufacture. A single 200 large rifle primer can launch a single dart assemblage reasonably accurately to 30 feet from the cartridge. Each assemblage is deflected to a predicted angle of flight when it collides with a center hinged cover as it exits the cartridge. This arrangement allows for longer flight distances and tighter, but still effective, dart spreads throughout the travel.

  • Patent number: 6626077
    Abstract: An intercept device for flying objects made of a light-weight, packable structure made of a pliable, tear resistant material that can be expanded to a large web-like structure by means of a deployment device, into the path of a flying weapon. To capture, hold and reduce the velocity of intercepted flying objects, activatable resistance bodies are incorporated into uniformly distributed masses that are connected to the perimeter of the web like structure. Contractable sections of the web, made of cable-like structures, connected to perimeter masses, act as drawstrings upon collision with flying object. This causes closure of the web around the flying object as a result of the mass's inertia and added resistance from deployable resistance structures that place tension on drawstring structures of the web. The flying object is subsequently captured within the web, held secure and it's velocity rapidly reduced.

Retainer assemblies provided near the rear ends of the tubular members include chambers which are in fluid communication with the interior of the gun barrel. The apparatus comprises a bola assembly having a central plug from each side of which extends a cord at the end of which are weights. The plug is insertable into the central tube of the guide assembly and the weights are insertable through the elongated tubes for releasable engagement with the retainer assemblies.

  • Patent number: 6295911
    Abstract: A break line launch energy damper and recoil limiting system for line charges absorbs and dissipates launch energy over time during deployment of line charges. This system limits the amount of recoil energy that can act upon the line charge and allows for linear deployment without recoil that might hinder the effectiveness of the rear lengths of the line charge. An elongate strength member connects the line charge to an inertial drag, such as a parachute and/or container for the line charge. A plurality of lines having different tensile strengths are appropriately connected to sequentially part when their tensile strengths are exceeded to thereby absorb and dissipate energy during deployment of the line charge.

  • Patent number: 6244261
    Abstract: A hand-held apparatus for projecting a line across an intermediate span includes a launching tube having one end connected to a source of propellant gas energy for launching a projectile, the other end forming an open muzzle adapted to receive and fire a line deploying projectile. The projectile is releasably attached to one end of the line attached to a source of line connected to the launch tube and containing a supply of line to be payed out during the flight of the projectile. An axially-mounted laser sighting device connected to the launch tube for sighting the tube in on a remote target for the projectile is also provided.

  • Patent number: 6240849
    Abstract: A projectile attachment is disclosed that has open-biased arm members that can be either mounted directly onto the projectile base or may be mounted to a mutual connection means which is then attached to the projectile base. The arms are compressed into a restrained position so that they may be inserted into the casing of the bullet. Upon firing, the arms extend to the unrestrained position. Upon impact the projectile penetrates the target then the extended arm members engage the target surface to cause widespread damage while slowing the projectile. The members may optionally have hook-like ends.

  • Patent number: 6223659
    Abstract: A line storage device prevents a line from becoming entangled. A channel formed in a piece of material defines a non-overlapping zigzag pattern. The line is laid in the channel and extends from opposing ends of the piece of material. The material supports the line in the channel until the line attains a threshold tension at which point the piece ruptures sequentially along the zigzag pattern from each opposing end. The channel can be formed in or on one or more surfaces of the piece of material.

  • Patent number: 6205903
    Abstract: A line charge has a series of spaced-apart warheads coupled to strength members and a detonating cord freely extends through bores in the warheads. A rocket motor at one end of the strength members pulls the line charge across an obstacle laden area. An anchored tether or drogue chute at the other end arrests flight of the line charge and it drops across the area. The thermoplastic, polymeric, or metallic strength members provide strain management to withstand the severe deployment forces and to preclude damage to the detonating cord. Strain is absorbed by the elastic deformation of the strength members coupled to the warheads. Strain also is reduced through direct dissipation of energy by dynamic frictional losses created between strength members, coupling components, and anchoring devices during deployment when slippage occurs between the strength members and coupling components and anchoring devices.
