  • Publication number: 20040050283
    Abstract: This invention relates to a gas generator having two or more compartments, each with a separate initiator, with one compartment discharging before another, i.e., the compartments discharge sequentially. Each compartment has the same propellants, but the propellants have different geometries in each compartment, which results in different rates of gas evolution from each compartment. The new gas generator is designed to reach maximum inflation at the same time as the current, single stage gas generators. However, the new generator has a more rapid initial inflation, followed by a more gradual inflation rate in the subsequent stages, improving safety to occupants.

  • Patent number: 6659013
    Abstract: Projectiles or war-heads with an inner arrangement for the formation of bulging zones (4,4a) are proposed, comprised of an enclosed bulging medium (1) which is terminal-ballistically substantially ineffective and is radially enclosed by a penetration material (2) which is terminal-ballistically effective, with the bulging medium (1) having a lower density as compared with the enclosing penetration material (2). This leads to the effect that on impact or on penetrating a target plate (3) the bulging medium (1) remains behind relative to the encompassing terminal-ballistic effective body (2) and is laterally increasingly bulged by the bulging material (1) which continues to flow in from behind. As a result of the high pressures, a conical (crowned) pressure and bulging zone (4,4a) is formed dynamically, which zone radially widens or fragments the passing ambient effective material (5,5a).

    Abstract: An apparatus for launching and dispensing multiple satellites into orbit includes a central structure and a plurality of satellites releasably bundled around the central structure to form a cohesive, single payload mounted on an upper stage of a launcher rocket. The central structure includes a central tube and an adapter shell that fits onto the upper stage of the rocket. Each satellite has the shape of a partial cylinder segment of which an outer wall is a cylindrical segment shell. The satellites are bundled and secured together around the central structure by tension bands, whereby the cylindrical segment shells form a load-bearing complete outer cylindrical shell that surrounds the central tube. This structure provides sufficient stiffness and strength to withstand the loads that arise during launch, while having a reduced mass. The satellites themselves, rather than the central structure, bear the loads during launch. This allows the central structure to be of relatively lightweight construction.

  • Patent number: 6272995
    Abstract: A high precision electro-mechanical fuze mechanism for a munition such as a hand grenade. The fuze mechanism includes an electromagnetic signal generator having an armature, a permanent magnet, a coil and a magnetic impulse generator (MIG) member. The armature is preloaded during assembly through the use of a spring. Releasing an actuating lever of the grenade allows the armature to begin spinning and to dissipate the energy stored by the spring. This causes a current to be electromagnetically generated in the coil, which is transmitted to an electronic control circuit in the fuze mechanism. The electronic control circuit implements two time delays from two separate timers which each must time out before the control circuit can send an electric firing signal to an electric detonator. Movement of the armature also causes a simultaneous movement of a rotor, which moves a stab detonator into a position closely adjacent the electric detonator.

  • Patent number: 5880396
    Abstract: Process for guiding an elongated missile, equipped with booster motor, sustainer, power source, control electronics, payload, and search head, from above, upon a target, such as a helicopter, where the missile, after ballistic flight, is braked before the target area by a drogue chute and is diverted into a position that is essentially perpendicular to the earth's surface over the target area so that the search head of the missile, which is suspended from the drogue chute, will be pointed downward, whereupon, after the search head has locked on the target, the drogue chute is separated and the missile is guided to the target by the sustainer, characterized in that, immediately prior to, before, or after the moment of drogue chute deployment, a lateral motor, located in the center of gravity of the missile, is turned on so that, first of all, in order to accelerate the tilt-off of the missile into the vertical, there is generated a force that is added vectorially to the force of gravity and that thereupon one

  • Patent number: 5864086
    Abstract: A spin-stabilized projectile containing a payload is presented. The projectile includes a projectile body with a payload chamber that may be laterally defined by a projectile casing, on top by an axial fixing device for a payload disposed in the payload chamber, and on the bottom, by a dividing wall. The projectile casing may include axial grooves on the inside, which on the contribute to the fixing of the payload and include intended break zones for freeing the payload. Below the dividing wall, an opening charge may be disposed, which includes complete radial contact and is axially spaced apart from the dividing wall by a damping device. The detonation of opening charge causes the projectile casing to immediately split open at the intended break zones to release, by centrifugal force, the payload from the payload chamber. The damping device prevents the payload from being damaged in the region of the dividing wall and prevents the release of the payload from being interrupted.

  • Patent number: 5760330
    Abstract: A delivery apparatus (11) for full-calibre submunitions or the like payloads (12) which are coaxially stacked in its load space (19) results in a system which operates in a fault-free manner when, for ejecting the payloads (12), detachment of the load space (19) from the rocket motor (17) disposed therebehind and detachment of the ogive (14) from the opposite end of the load space (19) are each promoted by a pyrotechnic charge (28, 31), with the load space (19) being braked as a result of being positioned transversely beside the trajectory (26) of the separated motor (17) which flies further along the trajectory and past the load space in a stable configuration and with the load space (19) only then being turned by a braking parachute (23) connected to its end (22). The load space tail (18) which thereafter then faces forwardly in the direction of flight is opened by detachment of a cover (25) and the load space (19) is pulled away from the payload stack (12--12) by means of the braking parachute (23).

  • Patent number: 5679919
    Abstract: A method and apparatus is for imparting, in a continuous sequence, a predetermined rotational movement to a warhead releasably housed in a protective canister and ejected out in ballistic ejection trajectories from the canister. The canister is spun to the desired rotational speed by flow of combustion gases through gas outlet nozzles discharging in the outer periphery of the canister and supplied from a central combustion chamber in which a propellant powder charge is combusted. The combustion gases are then led from the combustion chamber, in the final phase of the propellant charge combustion, through gas outlets facing towards the warhead and initially covered by the propellant charge and exposed as a result of the combustion, for ejecting the warhead out of the canister.

  • 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.
