  • Patent number: 8518197
    Abstract: Disclosed is an incendiary compound comprising spherical zirconium, titanium, or hafnium powder having an average grain size of 50 to 250 ?m as well as a thermosetting or thermoplastic micronized organic binder which is added to the powder at a quantity of less than 1 percent by weight. The incendiary compound is fastened in the projectile or warhead by pressing and then thermally treating the same in order to activate crosslinking of the thermosetting binder or melt the thermoplastic binder.
    Type: Grant

  • Publication number: 20110011296
    Abstract: The invention relates to a subprojectile (1) comprising a body, which is provided with a borehole (5) and consists of hard metal or heavy metal, an energy component (3) with or without a firing means (4) being incorporated into the borehole (5). The energy component (3) with or without a pressure-sensitive firing means (4) is fired or activated by air friction, by an ignition in the carrier bullet together with a firing charge, or at the latest when the target is hit.

  • Patent number: 4249466
    Abstract: A sabot projectile having a pyrotechnic composition, especially a flare composition, arranged at the projectile body, wherein only a part of the pyrotechnic composition protrudes into a recess adapted to receive the same and provided at the tail of the projectile body. The part of the pyrotechnic composition protruding out of the tail of the projectile body is surrounded by a shell or jacket.

  • Patent number: 4170178
    Abstract: A detonator containing octogen crystals for projectiles for initiating detonation or for the transmission of a detonation, wherein the octogen crystals possess a size greater than 75 microns and smaller than 150 microns, the relationship between the length and diameter of the crystals amounts to about 3:1, and the edges of the crystals are undamaged. To produce the detonator cap a mixture of different types of octogen crystals is enriched with the aforementioned size of preferred octogen crystals by wet sieving.

  • Patent number: 3945321
    Abstract: A shell possessing a substantially cylindrical shell casing in which there is contained an explosive mass and at the inner wall of which casing there bears a layer of substantially spherical-shaped projectiles of the same size which are partially embedded in the explosive mass and between which there is locacted a filler mass. The projectiles which are partially embedded in the filler mass are exposed to axial pressure in the finished fabricated shell in order to avoid displacement and detachment of the projectiles from the shell casing and the thereby resulting imbalance during firing of the shell.The method of fabricating such shell contemplates inserting a guide sleeve into the shell casing and between the shell casing and the guide sleeve there are embedded equal size spherical-shaped projectiles. The projectiles after being filled into the shell are exposed to pressure in the axial direction and thereafter the guide sleeve is removed.
