Benefits of technology

[0006] It is an object of the present invention to provide gun ammunition of the aforementioned type which, when used as directed, allows only a relatively small amount of carbon monoxide to enter the crew compartment of the combat vehicle, even with high rates of fire.

Problems solved by technology

As a result, the gas clouds contain poisonous gases and in particular carbon monoxide.
During a rapid re-loading of the gun, the poisonous gases in part flow into the crew compartment of the respective combat vehicle when the breech is opened, thus endangering the crew.
However, embedding oxidizers in the propellant powder does not prevent relatively high amounts of carbon monoxide from forming on the cartridge bottom side.

Embodiment Construction

[0016]FIG. 1 shows the bottom region 1 of a cartridge, having a case bottom 2 of metal and a combustible case 3. The propellant powder 4 within the combustible case 3 can be ignited with a centrally located propellant igniter 5.

[0017] According to the invention, a collar 7 that comprises an oxygen-releasing substance is arranged between the case bottom 2 and a cartridge-bottom region 6 of the combustible case 3.

[0018] Thus, if the cartridge 1 is positioned inside a gun barrel (not shown), then the propellant powder 4 is initially ignited with the propellant igniter 5, following the firing. The case 3 subsequently burns and sufficiently heats up the collar 7, so that it begins to release oxygen into the bottom region of cartridge 1 and thus also into the breech area of the gun.

[0019]FIG. 2 shows another exemplary embodiment of the invention, for which an oxygen-releasing substance takes the form of a ring-shaped element 8 that is positioned on the bottom part 9 of the propellant i...

Abstract

Gun ammunition having a propellant is provided. The ammunition being for loading from a closed ammunition hold into the loading chamber of a gun. The ammunition has a tail region and an oxygen-releasing substance arranged in the tail region. The oxygen-releasing substance is for releasing oxygen after ignition of the propellant in the loading chamber of the gun, the release of the oxygen being for oxidizing carbon monoxide that forms during the firing in the loading chamber into carbon dioxide.

Description

CROSS REFERENCE TO RELATED APPLICATION [0001] This application claims the priority of German Patent Application, DE 103 47 372.6 filed Oct. 11, 2003, which is incorporated herein by reference. BACKGROUND OF THE INVENTION [0002] The invention relates to gun ammunition provided with a propellant charge that can be loaded from a closed ammunition hold into the loading chamber of a gun. [0003] A negative oxygen balance frequently occurs during the combustion of high-performance propellant powders, such as the ones used for firing tank ammunition. A negative oxygen balance is when the oxygen contained in the propellant powder is not sufficient for a complete reaction with the propellant powder. As a result, the gas clouds contain poisonous gases and in particular carbon monoxide. During a rapid re-loading of the gun, the poisonous gases in part flow into the crew compartment of the respective combat vehicle when the breech is opened, thus endangering the crew. [0004] German Reference DE ...
