  • Safe-and-arm device for the fuze of a spin-stabilized projectile
    Patent number: 4942816
    Abstract: A safe-and-arm or securing device for the fuze of a spinning or spin-stabilized projectile which includes a fuze member and a supporting member in which a spherical rotor is rotatably supported, and which has a radial groove formed therein. The rotor possesses a bore having a detonator inserted therein, and in a peripheral region incorporates a groove which extends along a plane which is axially offset relative to the radial groove, and with a spreadable or expandable restraining medium being inserted into the groove. The restraining medium releases the rotor which is retained in its secured position only subsequent to the firing of the projectile through the securing element which is spreadable and axially displaceable under the effect of axial and spin forces and which allows the rotor, after its release, to be pioted in conjuction with the detonator into the armed position.

  • Method for the attacking of a target object from an overflying projectile and overflying projectile for implementing the method
    Patent number: 4907485
    Abstract: A method for the attacking of a target object from an overflying projectile, and wherein the projectile is equipped with a target detector for the activation of its warhead. Moreover, there is disclosed an overflying projectile which is equipped with a downwardly oriented target detector and with a warhead which is activated in dependence upon the target detection for the attacking of the target object. The method contemplates that the projectile be guided into a lower altitude of flight for the scanning of the target area, and upon detection of a target object is pulled up steeply into an ascending path, which has its tail end oriented towards the target object, so as to launch the warhead opposite the direction of flight which is in an ascending trajectory from the tail end of the projectile in a direction towards the target object.

  • Utilization of a material possessing a micro-duplex grain structure
    Patent number: 4892991
    Abstract: Deflection of laser beams, irrespective as to whether this is implemented within or externally of the laser itself; necessitating the utilization of metal mirrors or reflectors of high-quality which, in short, are designated as laser mirrors or reflectors. Laser mirrors of that type require an extremely good mirror surface, a high reflective capability and a good geometric planicity, as well as a high surface hardness. Brass possessing an inherently known microduplex matrix or grain structure provides a significant improvement in the properties of laser mirrors. A material of that type has, by nature, a microcrystalline structure, possesses a freedom from stresses, a high degree of stiffness, and a good material hardness.
