A heavy metal penetrator with a high tungsten content incorporating a central part or core formed of an alloy comprising from 85% to 97% in mass of tungsten associated with additional metals and which is enclosed by a peripheral sheath made of a more ductile tungsten alloy than that of the core. The sheath of the penetrator is made of an alloy comprising 30% to 72% in mass of tungsten, the core comprising nodules of tungsten bound in a matrix of a gamma phase &#x3b3;associating tungsten with additional metals, the two gamma phases being continuously joined to one another with no transition zone.

Penetrator incorporating a core enclosed in a ductile sheath and manufacturing process for such a penetrator

An arrow-type sub-caliber projectile has a piercing bar which is cylindrical about a longitudinal axis, extended by a conical portion, and is surrounded by a sabot made of a lightweight material and allows the firing of the projectile in a weapon. This conical portion has a tip of a heating-resistant material with a maximum diameter less than half the diameter of the bar, the tip being connected to the bar by a support structure having no ballistic effects, the bar having a flat front face which is perpendicular to the longitudinal axis of the bar, the flat front face area being substantially equal to the cross-sectional area of the bar, thus with no element with ballistic effects interposed between the flat front face of the bar and the tip.

Sub-caliber projectile with a fitted head structure

A sub-caliber projectile of the fin-stabilized type incorporating a sabot and a penetrator linked together by shape matching linking means, said linking means incorporating a first profile machined at a bore of said sabot and cooperating with a second profile on said penetrator, each of said first and second profiles having a shape according to a section in an axial plane that alternates teeth and grooves, the axial play between one of said teeth of said penetrator and one of said grooves forming the housing of said one of said teeth in said sabot being variable along the axis of said projectile, wherein said linking means incorporate a front part (F) and a rear part (R) in which the play, at a mean temperature, between said penetrator teeth and the housings of said teeth in said sabot is variable, the play, firstly, increasing between said median zone (M) of said sabot and a front end of said sabot and, secondly, increasing between said median zone (M) of said sabot and a rear end of said sabot.

An impact fuse includes a body containing a piezoelectric generator positioned on a bracket integral with the body. The piezoelectric generator serving as an anvil. The fuse includes a piston intended to mechanically contact the generator upon impact. The piston receives the impact forces transmitted by a cap. The fuse being characterized in that the piston is slidably fitted within the body and in that it includes plastically deformable means that are interposed between the cap and the body. The means are deformed by cap movement upon impact with a target via piston movement. The plastically deformable means is configured to be deformed in a manner that causes the piston to more gradually exert force on the piezoelectric generator.

Impact fuse

Sealing band for a projectile, the band being characterized in that it comprises a front sub-band containing at least two sectors, the sub-band having at least a conical profile in a tight fit with the matching profile of a groove of the projectile, the cone tip being placed towards a rear section of the projectile, with the sub-band attached to the projectile by a cylindrical skirt.

Sealing band for projectile, sub-caliber projectile and ammunition equipped with such a band

A sub-caliber projectile incorporating a penetrator and a sabot formed of several segments, the penetrator and sabot incorporating profiles that cooperate with one another so as to ensure the axial drive of the penetrator by the sabot when the projectile is being fired, such projectile wherein there is axial play (J) between the profile on the sabot and that on the penetrator so as to enable a limited relative axial displacement of the sabot with respect to the penetrator, means being provided to ensure the radial locking of the sabot segments by the penetrator in the foremost position of the sabot with respect to the penetrator, this locking no longer being ensured in the rearmost position of the sabot with respect to the penetrator.

Sub-caliber projectile, penetrator and sabot enabling such a projectile

A sabot for a projectile comprising at least two segments intended to surround and drive a sub-caliber penetrator, such sabot comprising a calibered thrust plate, wherein said sabot incorporates a body made of a light material, said body having at least one longitudinal insert made of a material having high mechanical properties, said insert having indentations cooperating with an external profile of said penetrator to allow it to be driven, said indentations extending those of said sabot body and which thus also cooperate with the external profile of said penetrator.

Sabot for sub-calibre projectiles

A perforating ammunition having a penetration body delimiting an internal cavity closed by a base which penetration body includes a front nose with at least one insert integral with the nose, the insert being a material denser than that of the body and arranged in a housing opening to the outside of the body.

Sabot for fin-stabilized ammunition

A device including a ring for linking a case and a projectile carrying a sealing band having a rear skirt providing low pressure sealing and a front rib lodged in a first groove in the projectile. The ring has a flared rear part connected with the case and a front part connected with the projectile by attachment means. The front part of the ring is lodged between the rear skirt of the band and the projectile and has a lip co-operating with the first groove or with a second groove in the projectile. A process for mounting the sealing band and ring to link the case and projectile includes sliding the sealing band and ring along the projectile in a single operation.

Device to link a case and a projectile and process to mount a band onto a projectile implementing such a linking device

A device for joining a first container to a second container to be inserted into the chamber of a weapon includes a first neck disposed adjacent a first face of the first container, a second neck disposed adjacent a second face of the second container and a deformable ring. The first container and the second container have container diameters that are less than a chamber diameter D1. The first face of the first container is alignable with a second face of the second container along a longitudinal axis. The second neck includes a circular cusp. The deformable ring is disposed around the first neck and includes an annular lip. The deformable ring is shaped to slide substantially parallel to the longitudinal axis toward the second container to engage the cusp. The deformable ring has a ring diameter D3 that is greater than the chamber diameter D1. The deformable ring is configured to decrease in diameter under deformation from the ring diameter D3 to the chamber diameter D1 when the first container is inserted into the chamber. As a result, the deformable ring disengages from the cusp and allows the first container to separate from the second container without requiring use of tools or manipulation by the operator.

Device for joining propellant charge containers and container having

The technical aspect of the invention relates to containers for a propulsive charge in at least two parts. The container (1a-1b)) according to the invention comprises a casing (9a-9b) demarcating an internal space, in which may be positioned, in particular, a propulsive charge, and it is intended to be rigidly affixed to a second container at one of their frontal faces (10a-10b), wherein it comprises means for the conduction of electricity, intended to receive and transmit a signal emanating from the weapon, as well as connecting means for providing, after the first container has been rigidly affixed to the second container, an electrical connection between these conduction means and other conduction means in the second container. Application for tank ammunition.
