Problems solved by technology

The downside of this ejection channel has to do with the fact that the shells and connectors mix in it and often become tangled, causing the machine gun to bulge and even scratch if the shells bounce back into the magazine

Embodiment Construction

[0048] Typically, items of ammunition 1 are connected and clamped to each other using connectors 2 to form a flexible chain or strip 3 of ammunition 1 ( figure 1 ). As a reminder, in terms of its composition, ammunition 1 generally consists of a bullet or bullet 4 , casing 5 , powder 6 , cap 7 and detonator 8 . In this case, this involves considering that the ammunition 1 has two calibers, namely the medium caliber ammunition 1 of 20 mm to 50 mm, and the small caliber ammunition 1 defined between 5.56 mm and 15 mm.

[0049] The chain or bar 3 of ammunition 1 has an undefined and unspecified initial size, which means that it must be remembered that the chain or bar 3 of ammunition 1 can be modified at any time by adding or removing ammunition 1 according to the needs defined by the mission in progress. The length of said chain or bar 3. However, in order to make full use of the chain or strip 3 of ammunition 1 , the latter must follow a fixed initial length, which cannot exce...

Abstract

The present invention relates to a device for ejecting (10) cartridges (5) and / or links (2) from a chain or ammunition (1) strip (3) connected to a main (19) and / or secondary (33) weapon in a turret (9) assembled on an armoured vehicle, the ejection device (10) comprising a plurality of structural elements defined geometrically and mechanically, enabling, after shooting ammunition (1), guiding ofthe movement of the cartridges (5) and / or the links (2) from the inside to the outside of said turret (9), along a predetermined path, and comprising means for vibrating at least one part of these structural elements to encourage said movement of cartridges (5) and / or links (2).

Description

technical field [0001] The technical field of the invention relates to the ejection of cartridge cases and / or connectors from at least one (or combination) of chains or bars of ammunition of a particular caliber, namely small to medium or "coaxial machine gun"), while medium calibers are associated with the primary weapon (called the "barrel"). Ejection is usually performed through an integral tandem structure with specific geometric and mechanical properties after firing from the inside to the outside of a turret mounted on any armored vehicle. [0002] The sequence of technical operations regarding the ejection of small-caliber and / or medium-caliber ammunition remnants can be summarized as a combination of two actions: i) recovery of any matter (stones, plants, etc.) that fell under gravity into a closed circular structure such as a tube ), and ii) transporting the material on a moving surface, such as a belt, provided with a vibrating device beneath it in order to alter so...
