摘要:
An existing projectile is adapted to a fire control computer instead of adapting the fire control computer to the ammunition, as has been the customary approach. The adaptation is carried out by providing the projectile with a different propellant charge powder but at least increasing the diameter of the flare while the length of the tail piece is kept constant.

A projectile body having a groove-shaped recess (2), in which a guide band (3) is disposed. To permit use of a relatively wide guide band (3), while preventing the band from being destroyed as the projectile body (1) passes through the gun barrel, and preventing significant copper-plating of the barrel, the guide band (3) is assembled from two partial guide bands (5, 6), with the relatively narrow, first partial band (5), which faces the base (7) of the projectile, comprising copper or a copper alloy and providing a seal against the propellant gases acting on the projectile rear under high pressure. The second, considerably wider partial guide band (6) essentially comprises plastic, and includes at least one hollow space (11), which lends it adequate deformation reserves with respect to the high surface pressure acting on this partial guide band (6) when the projectile body (1) passes through the barrel.

A propellant case includes a case sleeve having a longitudinal axis; a case bottom including a case bottom base; and an axially extending case bottom dome having a socket for supporting a primer therein. The case bottom base is releasably attached to the case bottom dome, while the case bottom dome is permanently attached to the case sleeve, whereby upon removing the case bottom from the case bottom dome, a connection between the case bottom dome and the case sleeve is preserved.

A propellant igniter assembly includes a housing having ignition channels for the passage of an ignition flame through the housing; an igniter part accommodated in the housing; and a booster part accommodated in the housing and frontally adjoining the igniter part. The booster part has a booster charge which includes a first partial booster charge adjoining the igniter part and composed of a readily ignitable substance and a second partial booster charge adjoining the first partial booster charge and being separated thereby from the igniter part. The second partial booster charge entirely obturates all the ignition channels. The second partial booster charge has a burning behavior and a mechanical stability such that the ignition channels remain obturated for a short duration even after ignition of the second partial booster charge, whereby a firing impact is first retained in the booster part and is subsequently abruptly released in a concentrated form through the ignition channels.

A cartridge ammunition includes a case having a case bottom; a propellant powder disposed in the case, a propellant igniter mounted centrally on the case bottom; and an arrow projectile having a rear length portion extending into the case towards the case bottom. At least those grains of the propellant powder which are situated axially beyond the propellant igniter are coated with an igniting substance.
摘要:
A method and an apparatus for producing a large-caliber ammunition unit including a combustible or partially combustible propelling charge casing and compacted or partially compacted propelling charge powder, to increase internal ballistic performance. It is known to partially or completely compact or compress the propelling charge powder in a cartridge casing. However, such methods generally cannot be employed for ammunition including a combustible or at least partially combustible propelling charge casing because of the lower strength of the relatively thin-walled combustible casing material, as this would lead to deformation and/or to reduced loadability of such cartridges. The present invention permits the compaction or partial compaction of the propelling charge powder of an ammunition unit including a combustible propelling charge casing in that a pressing mold or matrix is employed which directly encloses the propelling charge casing, with an appropriate annular gap being left free between the inner surface of the propelling charge casing and the outer surface of the press die in dependence on the grain dimension of the propelling charge powder grains to be compacted so that the propelling charge powder can be compacted almost without shear forces with respect to the inner surface of the propelling charge casing.

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.
摘要:
An incendiary composition (14) for a fin-stabilized kinetic energy projectile (1) which can be arranged in the tail region of the projectile (1) and, upon impact with a target (13), penetrates the target (13) as a separate unit behind the penetrator (2) of the kinetic energy projectile (1). To reach the objective of a high destructive effect caused by the incendiary composition (14) within a target (13), despite a small volume and a low mass, and to ensure that the incendiary composition is ignited securely by the shock waves generated upon impact, according to the invention, a titanium sponge is used as the incendiary composition (14), with an epoxide resin or a polyester resin used as a binder.

A method of making a cartridge ammunition includes the following steps: providing a cartridge case having a longitudinal axis; introducing bulk propellant powder into the cartridge case; and oscillating the cartridge case about its longitudinal axis for compacting the bulk propellant powder therein.
