  • Patent number: 8800359
    Abstract: The invention relates to a method for determination of the muzzle velocity of a projectile (2) when it emerges from the firing barrel (1) of a shoulder-held weapon. In order not to weaken the firing barrel, it is proposed that a transmitter (3) for transmission of signals be arranged on the end face of the firing barrel (1) and that two sensors (9, 10), which are arranged at a distance d from one another, be arranged in or on the projectile (2) in order to detect the signals transmitted by the transmitter (3) and that these sensors (9, 10) detect a pulse on flying past the transmitter (3), and that the muzzle velocity for the projectile (2) be determined from the time difference between the pulses detected by the two sensors (9, 10).

  • Publication number: 20040069174
    Abstract: The invention relates to a cartridge (14) which can be used in an anti-tank rocket launcher (10), comprising launching tubes (16) open at both ends, wherein a projectile (18) and a propelling charge cartridge (20) are arranged. To ignite the propelling charge, a non-electric igniting line (56) which is joined to the propelling charge cartridge (20) is used, said line exiting from the launching tube (16) at one end thereof The invention avoids direct ignition of the propelling charge, from an outer radial direction and dispenses with the use of the radial openings therefor in the launching tube (16). The launching tube can also be made from non-metal and mechanically weaker material, thereby considerably reducing the total weight of the cartridge (14) in a considerable manner.

  • Patent number: 4848238
    Abstract: An active munition element for combatting a target provided with a jamming device, the element including: a front charge; a rear charge mounted behind the front charge and having a hollow charge element; components connected for actuating each charge, the front charge being operative for developing kinetic energy in the target so as to neutralize the jamming device and the rear charge being actuated after the front charge to be effective against the target without interference; and a tube defining a narrow longitudinal channel having a smaller diameter than, and coaxial with, the rear charge, the channel extending forwardly from the rear charge and having a front end region housing the front charge.

  • Patent number: 4612859
    Abstract: The invention relates to a multiple purpose warhead which is provided with a spike-forming cladding, with projectile-forming layers and with preshaped splinters, respectively splinter layers. For the simultaneous combatting of hard and semi-hard material targets as well as soft targets the impact precision, the penetration capacity and thereby the effectiveness of the multiple purpose warhead is increased relative to the multiple purpose warheads of the state of the art.The multiple purpose warhead of this invention includes within a multiple purpose warhead casing 7 at least three effective parts 1, 2, 3. This arrangement achieves optimum, however, different, target effectiveness and a separate dosable explosive charge 6.1, 6.2, 6.3 corresponding to the different target requirements by providing corresponding different claddings for each effective part. There is provided between a first effective part formed as a hollow charge 6.

  • Patent number: 4545755
    Abstract: An apparatus for pressing a fluent powder into a rigid body comprises a die formed with an upwardly open and laterally closed pressing cavity adapted to hold a mass of the fluent particles to be pressed and a punch having a lower portion substantially complementary to and fittable in the pressing cavity and having a lower face engageable with the mass in the cavity. This punch is formed with a throughgoing vent passage having a lower end opening at the lower face and an upper end opening thereabove to the surroundings. An actuator can displace the punch relative to the die between an upper position clear thereof and a lower position engaged in the cavity and compressing the mass therein and through an intermediate position between the upper and lower positions. A valve body in the passage permits free gas flow therethrough when the punch is in and between the intermediate and upper positions and blocks flow therethrough between the intermediate and lower positions.

  • Patent number: 4306502
    Abstract: A load-carrying missile adapted for firing from barrel weapons and having a plurality of explosive charges disposed thereon with a plurality of projectile forming coverings distributed over the periphery of the missile and directed substantially perpendicular to the axis of the missile. The missile is provided with a parachute which is connected to the casing of the missile and which causes a directional braked descent of the missile in the target area.

  • Patent number: 4289073
    Abstract: A disc-shaped warhead adapted for being fired from a barrel weapon, and particularly for being stacked with a plurality of similar warheads in a load-carrying missile for ejection one after the other. The warhead has a plurality of slave missiles disposed in radially directed firing tubes, and a parachute connected to the warhead and causing a directional, braked descent in the target area. Each of the slave missiles has a proximity fuse to detonate it individually after reaching a predetermined distance from the ground or other target.
