  • Patent number: 9188417
    Abstract: A sabot is used for enclosing a payload, such as a missile or projectile, during launch. The sabot includes a series of panels that are held together prior to launch by engagement with a cap having protrusions or delay pins that maintain the panels in a closed condition. When the launch is initiated, the cap begins to slide out of engagement with the panels. The cap is configured such that the disengagement does not occur immediately upon movement of the cap; instead the protrusions are sized to delay opening of the panels until the sabot and missile have cleared the launcher. Then the panels rotate outward and drop away from a base the sabot, for example using self-releasing hinges. The base of the sabot may be configured to disengage from the payload by introduction of pressurized gases into a space between the base and an aft end of the missile.

  • Patent number: 6981450
    Abstract: A grenade dispensing mechanism for non-spin or low spin dual purpose improved conventional munition launched from inside a projectile. At a pre-determined point along the trajectory, the projectile time fuze which is set at the gun functions to provide initiation output to the payload expulsion charge assembly. The payload expulsion charge assembly contains a propellant which when ignited, produces a gas pressure acting on a pusher plate which acts as a piston. The gas pressure increases with time until the forces of the gas pressure acting on the pusher plate through the grenade payload to the base/tail assembly are sufficient to shear the thread attachment of the base assembly to the projectile body section. An obturator band serves to seal the expulsion gas pressures to prevent excessive gas blow-by as the payload canister assembly travels through the rifled projectile body section.

  • Patent number: 5649488
    Abstract: The non-explosive core of a reentry projectile is fixedly positioned within hollow casing of the projectile at a location maximizing conversion and transfer of kinetic energy to an earth bound target in response to the projectile's impact at a hypersonic velocity and at a steep impact angle to the surface of the earth. The hollow casing is formed of a material capable of withstanding high temperatures, therefore, not requiring any cooling and allowing for the hollow casing to be free of heat transfer medium that might otherwise impede the desired quick release of the core upon impact of the projectile. The core is in the form of a single dense metallic slug having a mass establishing a center of gravity and moments of inertia for the projectile as a kinetic energy warhead corresponding to that of an explosive or nuclear warhead without weapon system modification.

  • Patent number: 5619010
    Abstract: An apparatus and method for separating a warhead to be delivered to a target from a carrier missile flying at high speed in a first aerodynamic trajectory include a rocket motor attached to the warhead in the carrier missile and an ejection tube positioned obliquely in the carrier missile rearwardly and upwardly with respect to a longitudinal axis of the carrier missile from which the warhead is ejected by the rocket motor into a second aerodynamic trajectory having a substantially higher maximum flight altitude then the first trajectory. The warhead is separated from the rocket motor after ejection by aerodynamic forces created from the angle of the ejection of the warhead from the carrier missile and the relative flight velocities of the warhead and the carrier missile. The aerodynamic forces act on a connection between the rocket motor and the warhead, whereby the motor and warhead upon the burnout of the motor follow separate forward trajectories upon separation.

  • Patent number: 5398615
    Abstract: A method of separating from one another subcombat units transported by a rotationally-stabilized carrier body to a predetermined target area. The method comprises the steps of:ejecting the subcombat units and a plurality of masses or bodies from the carrier body;utilizing rotational energy from the rotationally-stabilized carrier body to generate axially directed separation forces in the masses or bodies, the separation forces acting concentrically in relation to a common center axis of the carrier body; andseparating the subcombat units from one another so that they spread out and each cover a predetermined portion of a target area by utilizing the separation forces in the masses or bodies to cause the separation of the subcombat units after their ejection from the carrier body.

  • Patent number: 5315933
    Abstract: A method of separating a sub-combat unit from a protective canister. The method comprises the steps of discharging the sub-combat unit from the protective canister by causing a displacement of a driving sabot within the protective canister. The driving sabot is displaced by an elevated gas pressure generated by the combustion of a gas-generating pyrotechnical charge. The displacement of the sabot imparts a trajectory to the sub-combat unit. The displaceable driving sabot is prevented, by arrest means interconnected between the driving sabot and the canister, from accompanying the sub-combat unit in its new trajectory. A division of the protective canister into a plurality of parts is caused. The division ensures a change in at least one of the trajectory and the velocity of the parts of the canister.

  • Patent number: 5277115
    Abstract: A method is provided for retarding the movement of the flip-out target tracker during a final part of a flip-out without the contents or journalling of the target tracker being damaged. The flip-out target tracker is on a sub-combat unit which is transported by a carrier body to a predetermined target area in order to be activated at the target area during flip-out of the target tracker. The target tracker scans the target area during the braked fall of the sub-combat unit and identifies and combats targets by means of an integrated warhead. The retardation is effected with a flexible brake band. The brake band is initially folded and attached to the target tracker at a first anchorage point in the proximity of a portion of the target tracker which, during flip-out, moves the longest distance. The brake band is stretched past an elastically deformable damper body secured in a main portion of the sub-combat unit.
