  • Patent number: 10976143
    Abstract: For the transport and handling of ammunition, the safety level is determined according to the amount of explosive used. Thereby, regulatory constraints are set for example for air transports, which barely suffice for a trial of projectiles. By a specific guidance of shockwaves resulting on impact on a target multilateral, high compressions are evolving inside the acting body (5?), which are initiating the same reliably without additional means or support agents. The subject of the invention aims at great savings of explosive without losses in the effect and significantly increases the safety during transport and handling.

  • Patent number: 10451392
    Abstract: Tracer ammunition for tracking the trajectory and/or the impact of projectiles in the target generally contains pyrotechnics. These pyrotechnics demonstrate various disadvantages, wherein the most serious is the continued burning of the pyrotechnics, even after penetration of the projectile in the target. This causes an increased risk of fire and acute injuries. A mixture of light metal and a carbon-containing substrate, ignites during firing of a projectile and burns during its flight by means of air oxygen introduced into the combustion chamber by way of tear-off edges, and produces a tracer that extinguishes in the target.

  • Patent number: 10330448
    Abstract: A fragmentation projectile in one aspect has a frontal cavity and defined fragments of medium to high density. The fragments are nearly form fitting together to form a compact projectile until its impact on the target. To achieve these specific mechanical properties, Additive Manufacturing (AM) methods are applied.
