Description

The The invention relates to a weapon system with caseless ammunition according to the preamble of claim 1.

at Ammunition big Caliber, for example 155 mm - ammunition, the propellant lighter is used separately. In caseless Ammunition becomes the propellant lighter, at which is a mechanical or an electric propellant charge igniter can, so far integrated into the propellant charge powder body. In contrast to sleeve ammunition must be with caseless Ammunition of the firing pin of mechanical propellant lighter in penetrate the propellant charge powder body or in an electric propellant charge lighter, the firing pin electrically drives the propellant charge powder body to contact. After the propellant charge ignition and the burning of the Propellant charge powder body must the firing pin or firing pin the passageway through the impact floor or through the wall of the cartridge chamber against the highly compressed, hot powder gas caulk. That is with a not to be neglected technical effort connected.

Of the electric propellant igniters is in a known manner by a piezoelectric spark gap or, for example, activated by an electric energy field, which is in the Is more elegant compared to a mechanical propellant charge ignition; here are However, electrical problems such. B. the contact resistance the contact o. The like. Barely avoidable.

Further defects a propellant powder body with integrated ignition element are that in addition to the above-mentioned technical effort the Ammunition, for example, in a fire failure must be completely discharged. That's especially possible Feeding damage not unproblematic. The discharge means a considerable weapon engineering Effort and needed Time. Furthermore is the production of the propellant lighter for caseless ammunition and their Integration in the propellant charge powder body more expensive and expensive as known, taken in metal ignition elements. Another shortcoming exists in the susceptibility, which is bigger as the susceptibility of sleeve ammunition.

From the US 4 282 813 A a weapon system with caseless ammunition is known which shows a weapon housing having a bullet bottom. In the bump bottom, a propellant charge powder cartridge chamber and a bullet cartridge bearing are provided one behind the other. In case of failure of the ignition element, the chamber is emptied via a feeder and then reloaded.

A powder body for caseless ammunition according to the DE 21 05 295 C1 has an integrated ignition means. In case of failure of the ignition, the entire powder body is replaced.

Of the Invention is based on the object, a weapon system of the above to create said type, in which the above-mentioned defects simple way are eliminated.

These The object is achieved by the Characteristics of claim 1 solved. Preferred embodiments or further developments of the weapons system according to the invention are in the subclaims characterized.

According to the invention Propellant charge powder body without a lighter made, so in addition also completely other hazard class or source of danger. The danger potential is comparatively lower.

Of the respective propellant charge powder body has one leading into his heart ignition channel on, the fluidically with a trained in the shock bottom Breech-ignition channel koaliert, which the respective ignition element assigned. The ignition elements are in the storey floor provided weiterschaltbar. According to the invention is advantageously a conventional propellant ignition element, which is a mechanical or an electrical ignition element can be traded, transported separately and in one located in the bump Recording room detonated. The pilot flame will be shortly as with sleeve ammunition - through the ignition channel brought to the propellant charge. The pilot flame out of the squib firing channel drives it in the ignition channel in the propellant powder body and to the booster or booster charge. In this way, there is the advantage that the initiation of the respective mechanical or electrical ignition element in the same proven type takes place, as in a case ammunition. Because the respective ignition according to the invention preferably a Zündelementgehäuse from Has metal, the Zündelementgehäuse serves simultaneously as a sealing element against the powder gas pressure and protects the firing pin or the electrical firing pin.

at a failure does not need all the ammunition, i. unload the cartridge too but it only needs the defective ignition element switched on and by a new ignition element to be replaced, which can then be initiated. Another The advantage is that a mounting of the ignition element in the propellant charge powder body completely eliminated. The Ammunition can consist of at least two parts, such as propellant bodies and Bullet exist, as well as one-piece, so without sleeve, his.

Further Details, features and advantages will be apparent from the following Description of a sectionally longitudinal section in the drawing clarified embodiment of the weapon system according to the invention with caseless ammunition.

The figure shows a weapon case 10 of the weapon system with caseless ammunition that has a bump 12 has, and in the z. B. a propellant powder body cartridge chamber 14 and a projectile cartridge chamber 16 are provided arranged one behind the other. The propellant powder body cartridge store 14 adjoins the bump 12 of the weapon case 10 at. To the bullet chamber 16 borders a barrel 18 on, from the weapon case 10 protrudes.

In the propellant charge powder cartridge chamber 14 are propellant powder body 20 and in the bullet chamber 16 there are projectiles 22 ,

The respective propellant charge powder body 20 has a leading into its interior ignition channel 24 up, the fluidically with a in the shock bottom 12 of the weapon case 10 trained shock bottom ignition channel 26 coalesces. In the bump 12 are a number of ignition elements 28 provided weiterschaltbar. For this purpose, the shock bottom 12 with a recording room 30 for a transport device 32 designed for transport, ie for the gradual switching of the ignition 28 is provided.

At the respective ignition element 28 it is a conventional ignition element, which is a Zündelementgehäuse 34 made of metal.

The ignition channel 24 in the respective propellant charge powder body 20 is dustproof and moistureproof. The respective propellant charge powder body 20 has an auxiliary or boost amplifier charge 36 on.
