  • Patent number: 4651649
    Abstract: A sabot for propelling subcaliber projectiles in gun barrels, with the projectile being annularly surrounded by the sabot. The sabot, as viewed circumferentially, is shaped as at least a two part substantially cylindrical jacket provided with an annular flange disposed in a forward end thereof, which annular flange serves as a reinforcing and sealing plate. A further annular flange is provided in an area of the rear end of the cylindrical jacket, with a space between the two flanges being at least partially filled with hollow fibers made of, for example, glass, carbon, or the like, with the space extending from the outer edge of the sealing plate to the rear annular flange.

  • Patent number: 4503776
    Abstract: Known projectiles with molded fragments are usually produced in the shape of steels or rollers produced with the aid of powder technology or in a flow compression process. The molded fragments are located in a dense packing in the wall of fragmentation bodies without being able to be brought into an orientation which is advantageous for the fragmentation effect. In order to enhance the fragmentation effect, the fragments are arranged with regard to their orientation and mutual spacing within a casting form in a pattern provided in an inner mold form, and subsequently provided with the cast material. Required through the form-fitting support of the fragments through protuberances projecting into the fragments, after the removal of the fragmentation body the recesses formed in the fragments can have incendiary charges pressed therein. Thereby the fragmentation is enhanced by the additional incendiary effect.
