Containers for propellant charges

The innovation concerns one consisting of partial cartridges., Combustible container for propellant charges with caseless, separately charged ammunition of any caliber.

The current state of the art is used for larger guns the propellant powder of the individual cartridges filled in silk bags or the like and for the trams, port placed in container. The total number of sub-cartridges arranged one behind the other and the size of the loads depend on the intended use and the desired range of the respective gun

3ie disadvantages of this design! Are the cumbersome tuning the propellant charge amount dur to the firing range, ι slimming T ^ zw. Adding the portion cartridges. With a large number of sub-cartridges, the longitudinal stiffness is very low, so that the threading of the charge and thus the rate of fire are negatively influenced.

In order to meet the recent demands for a higher rate of fire, the Packaging of the propellant powder in partial cartridges sought new ways to avoid the disadvantages listed above. According to the innovation, this will be done with a like input » explained container achieved in that the sub-cartridges can be plugged into each other and, except for the initial cartridge, have approximately the same training, which differs from the shape of the initial cartridge, the initial cartridge is appropriately held longer. Through this

the adjustment to the desired range as well as the lining up and removal of the cartridges are made easier, while at the same time sufficient longitudinal rigidity is guaranteed.

To further explain the innovation, the drawing, which shows an embodiment example and schematically, is used reproduces.

In the case shown, the total load consists of the five cartridges 3-7 * with the cartridge pouches in them marked with white color. They have different cargo weights. The partial cartridges not shown 1 and 2 do not exist at all ix connection with the cartridge pouches marked in white, they are used by Case-by-case used in a different cargo structure (green bag) that is purely ballistic.

The sub-cartridges consist of completely residue-free combustible material and apart from the sub-cartridge 3 all the same in construction. The length of the individual partial cartridges is adapted to the amount of propellant charge. The voting the amount of propellant powder to the desired range of the gun is done by plugging or unplugging of the different cartridges 4-7 »during the charge 3 (= initial cartridge 3) is always fired.

As the figure shows, the partial cartridges 4-7 have on the closed side tapers 8, into which the following cartridge with the help of wall extensions 9 can be attached or detached therefrom. The tapering of the sub-cartridge 7 is necessary in order to allow the container through the im Tube to be able to insert the round shoulder of the cargo space.

The sub-cartridges 4-7 are all with a corresponding trained lid made of combustible material closed.

The ignition side of the partial cartridge 3 is the combustion technology worst place. To get through here, installing a End cover, which is the same as with the other partial cartridges this closes, to avoid an accumulation of material due to a double wall thickness, the partial cartridge 3 is opposed the other cartridge part rotated by 180 ° and designed as a simple, open cylinder.

Since the partial cartridge 3 is fired in any case, regardless of which combination of partial cartridges is selected, a cover is no longer required. If this partial cartridge were not turned over, the container would have to be closed with a cover on the ignition side, and this would result in a double wall thickness in the area of this location, which is unfavorable for combustion technology.

The double wall thickness of the partial cartridges 4-7 is more favorable from a combustion point of view, because this accumulation of material at twice the wall thickness is located directly in the flame front. Appropriate tests have shown that these double wall thicknesses, due to the cover and the walls of the attached, combustible partial cartridges, burn completely when bombarded in the weapon.

With this construction, the disadvantages of the cartridge pouches made of silk or similar pouches that have been used up to now are eliminated avoided. This allows you to quickly match the amount of charge to the desired range of the weapon and a good longitudinal stiffness, d. H. a high rate of fire.

Claims (4)

Debit claims 1) Combustible container for propellant charges consisting of partial cartridges with caseless, separately charged Ammunition of any caliber, characterized in that the sub-cartridges (3-7) can be plugged onto one another and except for the initial cartridge (3) about the same, from the shape of the initial cartridge (3) have different training, the initial cartridge (3) is expedient is held longer. 2) Container according to claim 1, characterized in that the partial cartridges (4 - 7) have tapers (8) on the closed sides, into which the following Cartridge can be plugged on or detached from it with the help of wall extensions (9). 3) Container according to claims 1-2, characterized in that the cartridges (3-7) are completely residue-free burning material. 4) Container according to claims 1-3, characterized in that the cartridge (3) is designed as an open cylinder _ is inserted and rotated by 180 °.
