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.

Sabot projectile having a pyrotechnic composition

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.

Detonator containing octogen crystals for projectiles and method of

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. A filler mass is filled into the shell casing while the same rotates for such length of time until the projectiles are partially embedded in such filler mass and an explosive mass is filled in a liquid state into the shell casing so that the projectiles have the remaining portions thereof embedded in the explosive mass.
