  • Patent number: 9032858
    Abstract: A reactive protection arrangement for protecting stationary or mobile objects against threats posed by hollow charges, projectile-forming charges or kinetic energy penetrators is secured to the side of the object to be protected that faces the threat in a fixed or movable manner, and includes at least one protective area arranged at an inclination angle to the threat direction. This protective area comprises a front cover that faces the threat, and a rear cover that faces away from the threat and is spaced apart from the front cover and, is configured as a bulging arrangement. At least one fixed or movable reactive middle layer or reactive zone is present between both covers which includes at least two reactive partial areas each having at least one explosive field, wherein the reactive partial areas are plugged on all sides by means of the delimiting covers as well as lateral separating layers.

  • Publication number: 20090050041
    Abstract: A watercraft includes a support structure and a protected space, object or the like within an outer shell of the support structure. To protect the space, object, or the like, for example, a sensitive subassembly in the watercraft, against threats posed by shaped charges, a protective device is positioned between the outer shell and the sensitive subassembly. The protective device includes a multitude of reactive protective elements arranged in a flexible support construction oriented at an angle to the direction of threat. And the support construction is connected, such as, with positive locking and/or friction locking and/or with substance-to-substance bond, to the support structure of the watercraft.

  • Patent number: 7231876
    Abstract: A highly effective and also inert active penetrator, an active projectile, an active airborne body or an active multipurpose projectile with a constructively adjustable or settable relationship between penetrating power and lateral effect. The end ballistic total effect which is obtained from the penetrating depth and covering the surface or stressing of the surface is initiated in an active case by means of a releasable arrangement or installation which is independent of the position of the active body.

  • Publication number: 20070006766
    Abstract: A hybrid polyvalent projectile or warhead with an active means such as a fragmentation, disk, ring, hollow-charge or P-charge head in conjunction with a module comprising an active laterally effective penetrator includes a pyrotechnic unit serving at the same time for the active laterally effective penetrator and the active means as a producing/accelerating element. The terminal-ballistic efficiency of ALP projectiles, which is reduced at low impact velocities, is ensured by an additional device which as a pyrotechnic unit produces an axial action or accelerates fragments in the desired direction. The explosive of an HC-portion with a triggering device which can be of any design configuration at the same time provides the pressure for the adjoining ALP-module.

  • Publication number: 20060162539
    Abstract: The invention describes a rigid or flexible pyrotechnic protection surface which is free or integrated into a housing, for medium-heavily and lightly armored vehicles, protection arrangements and surfaces to be protected, corresponding to FIG. 1, with a single-layer or multi-layer carrier (4) of any configuration which is inclined in the region of action of the threat and pyrotechnic layers (2, 3) mounted on the carrier on both sides. Shock waves and reaction gases are formed by the firing of both layers and are accelerated both in opposite relationship to and also in the direction of the penetrating hollow charge threat (1). In that way both the front powerful blast elements and also a great blast length are disrupted and thus lose their penetration capability or are at least greatly diminished in respect of their residual power. The pyrotechnic protection surface is disposed in a condition of dynamic equilibrium over the entire period of action.

  • Publication number: 20060162538
    Abstract: A protective device for protecting armored vehicles from hollow-charge projectiles includes at least one protective module that is mounted in front of the exterior of a wall to be protected. The protective module is moved out of an inoperative position, in which it is situated in a predetermined position, and into an active position, in which at least partial areas of the protective module have a greater distance from the wall to be protected compared to the inoperative position. The protective module can be constructed from a number of components, which can be displaced relative to one another and which, as a result of a displacing motion and/or pivotal motion, can be displaced out of the inoperative position and into the active position in which they are interlocked.

  • Patent number: 6789484
    Abstract: Projectiles or war-heads with an inner arrangement for the formation of bulging zones (4,4a) are proposed, comprised of an enclosed bulging medium (1) which is terminal-ballistically substantially ineffective and is radially enclosed by a penetration material (2) which is terminal-ballistically effective, with the bulging medium (1) having a lower density as compared with the enclosing penetration material (2). This leads to the effect that on impact or on penetrating a target plate (3) the bulging medium (1) remains behind relative to the encompassing terminal-ballistic effective body (2) and is laterally increasingly bulged by the bulging material (1) which continues to flow in from behind. As a result of the high pressures, a conical (crowned) pressure and bulging zone (4,4a) is formed dynamically, which zone radially widens or fragments the passing ambient effective material (5,5a).

  • Patent number: 6182881
    Abstract: A stud driver for driving fastener studs in place with the aid of a propelling piston moved by a propellant contains a return spring concentrically surrounding a piston rod of the propelling piston. The return spring has roughly the shape of a relatively thin-walled cylindrical sleeve of elastomeric material reinforced at regular intervals by metallic ring disks. These metallic ring disks prevent any uncontrolled deformation of the elastomeric sleeve in high-speed movement of the propelling piston.

  • Patent number: 4967666
    Abstract: A warhead for use against fortified or armored targets has an axially extending common housing. A forward hollow charge is located in the housing adjacent the forward end. A follow-up projectile is located in the housing between the hollow charge and the rearward end. When the housing strikes a target an ignition system is activated first igniting the follow-up projectile and then igniting the hollow charge, so that the hollow charge opens a hole in the target and then is followed by the follow-up projectile aligned with the hole.

  • Patent number: 4642928
    Abstract: An insert for a weapon barrel for facilitating the firing of a small caliber ammunition comprises a tubular member having a bore defining a distinct caliber with one end having an exterior surface ending in a raised shoulder forming an abutment for a compensating bushing positioned on the exterior surface and abutting the shoulder. A sleeve is positioned on the exterior surface alongside and abutting against the bushing. This end of the insert carries a first locking mechanism for locking the sleeve radially in the barrel. This includes a tapered spreader sleeve which engages with a tapered exterior surface of the sleeve positioned on the insert adjacent the compensating bushing. The spreader sleeve is urged into bearing engagement with the tapered surface of the other sleeve by means of a knot threaded over the insert and advanced toward the spreader sleeve. A safety key is insertable through an opening in the sleeve and it engages in a longitudinal slot formed on the insert.
