Each of the fins (2) comprises a straight section (14) and a connecting section (13) connecting the straight section (14) to the pivot (5) and being configured so that the plane of the straight (14) section is offset from the pivot (5) axis.

Abstract: A projectile (1) for a small arms weapon. The projectile (1) comprises a projectile body (3) and a plurality of external peripheral fins (2) pivotable from a radially un-deployed position to a radially deployed position. When in the radially deployed position, each fin (2) is moveable in longitudinal direction into an engaged position with the projectile body (3) for radially securing the fin (2).

Abstract: A cartridge for a small arms weapon, comprising a cover for housing a projectile; a metal cap at a rear end of the cover; a propellant charge located inside the cover at the rear thereof; and a gas seal element located inside the cover adjacent to the propellant charge and having an annular sealing formation projecting rearwardly towards the propellant charge and being outwardly deformable on detonation of the propellant charge for sealing against an internal surface of the cover. The metal cap has a rim extending longitudinally over a portion of the external surface of the cover for supporting the cover where the sealing formation first seals against its internal surface.

Abstract: A small arms projectile for a small arms weapon is provided within a cartridge cover (1). A release element (15) is provided for preventing movement of the projectile's initiator (11) into an armed position. A channel (5) is formed between the initiator (11) and the projectile's explosive charge (8) and a slidable shield (6) is provided therein. An insert element (10) is also located in the channel for preventing movement of the shield (6) into its armed position. The insert element (10) is held in place by the cartridge cover (1). When the projectile exits the cartridge cover (1) following firing, the insert element (10) is configured to move out of the channel (5) to allow the shield (6) to move into its armed position.

Abstract: Projectile for a small arms weapon having a barrel. The projectile comprises a projectile body; a plurality of external peripheral fins; a coupling for each fin to mount the fin to the projectile body to enable pivotal movement of the fin from an un-deployed position to a deployed position and to enable displacement of the fin in a radial direction of the projectile body; and means to bias displacement of the fin in the radial direction.

Abstract: A small arms projectile for a small arms weapon is provided within a cartridge cover (1). A release element (15) is provided for preventing movement of the projectile=s initiator (11) into an armed position. The release element (15) is held in an engagement position by the cartridge cover (1). Also, a channel (5) is formed between the initiator (11) and the projectile=s explosive charge (8) and a slidable shielding means (6) is provided therein. An insert element (10) is also located in the channel for preventing movement of the shielding means (6) into its armed position. The insert element (10) is held in place by the cartridge cover(1). When the projectile exits the cartridge cover (1) and the weapon=s barrel following firing, the release element (15) is configured to move out of the engagement position to release the initiator (11), and the insert element (10) is configured to move out of the channel (5) to allow the shielding means (6) to move into its armed position.

Abstract: A small arms projectile for a small arms weapon, which projectile comprises a warhead having an explosive charge, an initiator, and a firing pin. The initiator has safe and armed conditions and is capable of detonating the explosive charge of the warhead when the initiator is in the armed condition and impacted with sufficient force by the firing pin. The projectile further comprises a shielding device positioned between the initiator and the explosive charge of the warhead, which shielding device is slidable from a safety position in which the shielding device shields the explosive charge of the warhead from the initiator, to an armed position in which the initiator is capable of detonating the explosive charge of the warhead. The shielding device is slidable from the safe to the armed position in response to the initiator moving from the safe to the armed condition.

Abstract: A projectile for a weapon comprises an axially movable firing pin, an initiator actuable when impinged by the firing pin, a plurality of external peripheral fins movable from a radially inward position to a radially outward position when the projectile leaves the weapon, fin engaging means for moving each fin from the radially inward position to the radially outward position and for maintaining each fin in the radially outward position, and internal actuating means for actuating the fin engaging means to engage and thereby move the fins to deploy from the radially inward to the radially outward position as the projectile leaves the weapon.

Abstract: A small arms projectile for a small arms weapon, which projectile comprises a warhead (116) having an explosive charge (not shown), an initiator (102), and a firing pin (not shown). The initiator has safe and armed conditions and is capable of detonating the explosive charge of the warhead when the initiator is in the armed condition and impacted with sufficient force by the firing pin. The projectile further comprises shielding means (106) positioned between the initiator and the explosive charge of the warhead, which shielding means is slidable from a safety position in which the shielding means shields the explosive charge of the warhead from the initiator, to an armed position in which the initiator is capable of detonating the explosive charge of the warhead. The shielding means is slidable from the safe to the armed position in response to the initiator moving from the safe to the armed condition.

Abstract: A projectile (1) for a small arms weapon having a muzzle, the projectile having a casing (2) and fins (3), pivotally mounted upon said casing and urged outwardly of the casing, for automatic deployment after leaving the muzzle; wherein the casing is disposed within a cartridge having a sleeve surrounding the casing and fins; the cartridge also containing a propellant charge intended, when detonated, to propel the projectile out of the muzzle; and wherein shielding means (6) is provided to shield said fins and/or their pivotal mountings, at least in part, from the detonation of said propellant.

Abstract: The invention provides a safety system for a small arms projectile in which an initiating device is impacted by a firing member in order to detonate a main explosive charge. The system requires the firing member to be retained in a safe position in relation to the initiating device by at least two independent mechanisms. The firing member is initially supported in a forward position, in which it assists in holding the initiator device in a safe condition, and is caused to move rearwardly, through inertia, when the projectile is fired, destroying one of the retaining mechanisms and allowing the initiator device to adopt a primed position in which it can be activated by the firing member which at this time is retained by the other retaining mechanism which is automatically released when the projectile is in flight.
