A deconfinement device for the casing of a piece of ammunition enclosing an explosive load able to be ignited by a priming fuse, said device comprising a connecting ring linked to the casing and enabling the priming fuse to be joined to said casing, wherein said device incorporates a structure to ensure a weakened and shearable link between said fuse and said connecting ring, said link being sheared further to an increase in the pressure inside said casing, said connecting ring incorporating a base forming a plate that can be projected onto said explosive load during the ignition of said fuse, said base being able to be fractured by the presence of pressure inside said body of said projectile.

Sabot for fin-stabilized ammunition

A casing for a propellant charge for a piece of ammunition comprises a projectile and a stub. The casing comprises a substantially cylindrical envelope and a closing cover. The cylindrical envelope is made of a plastic material and is in the shape of a lattice formed of strands defining openings. The lattice is formed by a repetitive rectangular mesh. The width of the mesh openings is less than a predetermined diameter of a grain of the propellant charge intended to fill the casing.

Method and apparatus for wedging submunitions within an envelope of a

The technical field of the invention relates to devices providing for the ejection of a plurality of payload elements from the casing of a carrier shell. The ejection device according to the invention includes a pyrotechnic composition placed in a head and intended to create, after ignition, a gas pressure that pushes a piston over a short distance so as to displace towards a base a moving assemblage having a pusher plate and payload elements, and to eject the base, the piston then being stopped relative to the head and having an orifice which allows the gases to pass towards the moving assemblage so as to push the latter. The device includes braking means disposed between at least a part of the moving assemblage and the shell casing. This invention is applicable to mine-dispersing carrier shells.

Device for ejecting payload elements from the casing of a carrier shell

The invention relates to carrier shells which can eject a payload in flight. A carrier shell for transporting a payload includes a body closed at one of its ends by a base and at the other by a head, inside of which is placed a pyrotechnic composition for generating gases intended to act on a piston at the time the payload is ejected. The shell includes an attachment between the piston and the shell after ejection of the payload. This invention is applicable to mine-dispersing carrier shells.

Carrier shell ejecting a payload by means of a piston

The technical field of the invention is that of carrier artillery shells. The carrier shell according to the invention is intended to transport at least one payload and contains a casing on which is placed at least one spinner band, the casing being closed at one of its ends by a base and at the other by a head inside of which is placed a gas-generating pyrotechnic composition intended to act on a piston at the time the payload is ejected; the shell being characterized in that the means by which the payload is spun by the casing includes lugs provided on an extension of the head and which interact with notches provided on an upper face of the piston, as well as means to cause the piston and the payload itself to spin together. This invention is applicable to mine-dispersing shells.
