  • AMUNITION WITH PROJECTILE CONTAINING NO EXPLOSIVE MATERIAL IN ORDER TO CREATE A MULTI-SPECTRAL TARGET SIGNATURE
    Publication number: 20140305328
    Abstract: An ammunition is proposed with an explosive-free missile that releases, upon dismantling at the target a fuel or fuel mixture as flammable air-fuel mixture, being caused to spontaneously react by at least one, by impact dismantling triggered, explosive-free, spark-generating ignition mechanism. The thus produced optical and thermal target signature can be detected with the naked eye, as well as with rifle scopes or other optical target detection systems, as well as with night-vision and thermal imaging devices.

  • Activation unit for explosive masses or explosive bodies
    Patent number: 8714089
    Abstract: An activation unit for explosive masses or explosive bodies includes an ejector tube and high-performance heating elements mounted around the ejector tube, each made of at least one heating wire supplied with electrical power by a control unit. Each heating wire is enclosed in a casing and embedded in a material minimizing heat loss. When the explosive body is passed through the activation unit, the jacket surface of the explosive body contacts the individual elements of the activation unit in a direct or non-contact manner. Thermal energy is transferred to the explosive body by means of the heating wires, and the body ignites at the contact points. A further activation unit includes heating elements in the ejector tube, at least partially fed longitudinally through the ejector tube, made of heating wire clad with CrNi steel and contact plates soldered thereto.

  • Breech drive for a weapon
    Patent number: 8616112
    Abstract: A drive for a weapon is provided, wherein rotational motion of a motor is converted to a forward or reverse motion of the breech in a simple manner using the Scotch yoke principle. In order to allow rest periods of the breech in the end positions, the crank radius is defined by a control cam, which changes when the crank is rotated. The hinge pin of the crank may be externally driven via a pinion shaft. A yoke pin is arranged in a groove of the crank so as to be radially displaceable and carries the breech carrier or the breech in a groove extending transversely to the direction of fire via a sliding block. Two rollers are arranged on the crank pin and run in control cams in the weapon or crank housing. The control cam is subdivided into different sectors/sections, thereby achieving the desired motion of the breech.
