摘要:
An arrangement for wirelessly setting, i.e. timing, ammunition provided with a programmable fuse and disposed in a gun barrel, which arrangement does not require complicated structural measures in and at the gun barrel and is not subject to the pressure and temperature influences generated by the propelling charge gases. The arrangement includes a simple and protected data transmitting unit fastened adjacent the beach of the weapon on, e.g., the interior wall or ceiling of a turret of an armored vehicle, a holding arm fixed to the weapon cradle or directly to the rear breech housing for the weapon, a special receiving antenna on the rear cartridge base or cartridge collar of the loaded ammunition, and a free optical data transmission path between the transmitter and the antenna.

A tank turret including an armored turret housing having a front side provided with solid front armor, and a pivotally mounted gun including a cradle shield, cradle, recoil device and rearward breech block housing being arranged in the turret housing. The armored turret housing, or at least parts of it, are used to increase recoil mass of the gun.

A weapon system includes a carrier vehicle and a vehicle dependent mortar, wherein the carrier vehicle has a crew space and a weaponry space to house the mortar, and the mortar is charged in an index position with mortar grenades, with several sheddable propellant modules on the tail shaft thereof. The weapon system avoids manual loading of the mortar with mortar grenades because an automatic loader is arranged in a weapon space separated from the crew space by a separating wall. The loader transports the mortar grenade from a magazine in the weapon space into the index position of the barrel of the mortar and axially inserts it into the mouth of the barrel, and an automatic shedding device is arranged in the weapon space to automatically remove unnecessary propellant modules from the mortar grenade after fixing target parameters and before insertion of the mortar grenade into the barrel.

A missile includes a warhead accommodated in an inner space at a front portion of the missile; a ball joint being in alignment with the longitudinal missile axis and pivotally supporting the warhead; and an aiming device for placing the warhead into a desired pivotal orientation. The aiming device includes a plurality of inflatable vessels arranged axially adjacent the warhead in a distribution about the missile axis. Each vessel has a first end oriented toward the warhead and a second end oriented away therefrom. The vessels are supported at their second end by a disk situated in the inner space of the missile. A gas generator is coupled to each vessel for charging the vessel with a gas to place the vessel into its inflated state. In the inflated state each vessel exerts a torque on the warhead about the ball joint by an engagement between the first end of the respective vessel and the warhead. Further, an electronic control system is accommodated in the inner space of the vessel. The electronic control system is connected to each gas generator for actuating a selected gas generator to place the warhead into a desired inclined orientation relative to the missile axis.
摘要:
A sub-caliber projectile having a large length to diameter ratio. The projectile includes in coaxial alignment a main body, an intermediate body and a head penetrator. At least the main body consists of a tough material having a high density which is achieved by means of a high content of tungsten or depleted uranium. The intermediate body consists of a macroscopic homogeneous material having a relatively high brittleness. The main body, intermediate body and head penetrator have abutting end faces by means of which they are joined.

A vane assembly for a projectile has a carrier carrying a plurality of pivots, having at the pivots respective carrier elements, and adapted to be secured to an end of the projectile. Respective vane elements are each pivotal on the pivots between an inner position lying immediately adjacent the respective carrier element and within a projection of the projectile and an outer deployed position projecting beyond the projection. Respective heat-destructible pins engaged between the vane elements and the respective carrier elements normally retain the vanes in the inner position and release the vanes for movement into the outer position when destroyed by heat. The carrier element is a rib of the carrier against which the respective vane lies when not deployed. In addition, relative to a normal longitudinal direction of travel of the projectile carrying the assembly, the vanes extend longitudinally in the direction and have relative to the direction front leading ends engaging the respective pins and rear trailing ends at the respective pivots.
摘要:
A tilt-equalization arrangement for steep angle firing guns. The barrel of the gun has secured to its rear end a ball pin which is swivelably mounted within a ball socket. The ball socket is secured to a base plate. Forwardly of its rear end the barrel is provided with at least one longitudinally adjustable aligning post. The aligning post is slidably movably mounted on a circular ring segment forming a guide rail for the aligning post. This guide rail is vertically adjustable at its opposite ends so that it forms an adjustable leveling plane for the aligning post, with the ball pin forming a fixed support point and also being situated at the center of the circular ring segment forming the guide rail.
摘要:
A tank mortar having a magazine receiving a plurality of fin-stabilized projectiles which can be selectively aligned with the barrel. The barrel is movable relative to the magazine to enable sealing engagement of the barrel with the selected magazine chamber. The weapon frame which rotatably receives the magazine has an upper portion in which the bottom of the barrel is axially shiftable, e.g. by a bayonet arrangement, and a lower portion which sealingly engages the bottom of the munition chamber which is aligned with the barrel includes the firing element which triggers the displacement of the projective from the round chamber through the barrel. The base of the weapon frame is also provided with a ball received in a socket which is shiftable to traverse the weapon.

An elastic spring element includes a fiber-reinforced ceramic that is resistant to temperatures greater than 1,000° C. The fibers are in the form of endless fibers and the elastic spring element has a corrugated geometric shape. The elastic spring elements may be used for sealing a control surface against hypersonic flow.

The deicing composition described comprises essentially a) from 87 to 99.45% by weight of an alkali metal halide and/or an alkaline earth metal halide, b) from 0.5 to 10% by weight of an alkali metal silicate and c) from 0.05 to 3% by weight of an alkali metal phosphate. It can be employed in solid form (powder, granules and the like) or as an aqueous solution. It ensures a short thaw time and protects metals, especially steel, against corrosion.
