Abstract: A muzzle brake for a gun having a substantially cylindrical body intended to be positioned in the extension of a gun barrel. The body has two stages of propellant gas reception vanes and is perforated by vents directing propellant gas towards the vanes. The brake has one deflector to deflect the flow of gas and is positioned between the vents of the second stage of the vanes and a front profile of the first stage of the vanes.

Abstract: The invention relates to a weapon system incorporating a cannon mounted in a cradle and intended to be carried on board a vehicle wherein the cradle is integral with a plate able to be positioned on the ground by the vehicle using a maneuvering arm? the cannon being able to fire from the plate positioned on the ground.

Abstract: A muzzle brake for a gun comprising at least one substantially cylindrical body intended to be positioned in the extension of a gun barrel, said body incorporating at least two stages of propellant gas reception vanes, said body being perforated by vents directing said propellant gas towards said vanes, wherein said brake incorporates at least one deflector means to deflect the flow of said gas, said means positioned between said vents of the second stage of said vanes and a front profile of the first stage of said vanes.

Abstract: An artillery weapon includes a cradle, a recoil mechanism body, a flange that fastens the body to the cradle, first rigid fastening structure for fastening the flange to the cradle and second fastening structure for fastening the body to the flange.

Abstract: A manual breechblock opening device that actuates a breechblock lever to open a wedge breechblock of a gun against an elastic return force includes a manual control member, a drivetrain and a holder. The manual control member is disposed within reach of an operator. The drivetrain includes a rotating output shaft coupled to the breechblock lever and a rotating input shaft coupled to the output shaft and coupleable to the manual control member. Actuating the manual control member rotates the drivetrain in a first rotational direction and causes the output shaft to engage the breechblock lever and to open the wedge breechblock. The blocking member is coupled to and disposed to prevent the rotation of the drivetrain in a second rotational direction that is opposite the first rotational direction.

Abstract: An anti-buckle fitting for a large caliber gun barrel, the fitting being constituted by an envelope that surrounds the barrel at a distance therefrom and of a length that is substantially equal to the outside portion of the barrel, the fitting comprising a front ring fixed near the free end of the barrel and a back ring fixed near the fume extractor of the barrel, and wherein the envelope is in the form of two half-shells assembled together by link means.

Abstract: A maneuvering device for a recoiling mass of a piece of artillery. The maneuvering device includes first and second ends that are attachable, respectively, to a recoiling mass and a cradle of the piece of artillery. The present invention is applied to the inspection of correct functioning of the recoil mechanism of a large or medium caliber piece of artillery during the counter-recoil of the recoiling mass.

Abstract: A breech block has, for each cheek of a breech ring, at least one bearing surface facing a rear of the breech. The bearing surface is adjustable to slide along a paired bearing surface of a matching bearing element of the cheek and bears on the paired bearing surface to transfer strain to the cheek generated during firing of a round. The bearing surface of the breech block and the paired bearing surface of the cheek of the breech ring face each other so that the plane of each of the matched bearing surfaces intersects a plane defined by the axis of the barrel and a horizontal line along a half-line terminating at the axis. The half-line defines an angle greater than 90.degree. with respect to the axis.

Abstract: An assembly includes a rod, an element and a blocking part insertable into and removable from the element. The blocking part is arranged to be associated with the element in a first position wherein the blocking part lies in the trajectory of a rod portion of a circumference of the rod, thereby preventing relative translation of the rod. The assembly is arranged so that, as soon as the blocking part occupies the first position, the element supports the blocking part and prevents its movement.

Abstract: A weapon is fitted with a barrel that is screwed into a breech ring and is mobile in axial translation with respect to a cradle. The assembly also comprises removable fastening structure to fasten the breech ring directly onto the cradle and relative coaxial centering structure for centering the cradle and the breech ring.

Abstract: A weapon (10) includes a breech block (12) moving between a closed position in which breech block (12) seals off a chamber (17) and an open position in which chamber (17) is open to receive ammunition from a loading tube (13).The means forming lock (16) is designed to hold breech block (12) open and unlocking means (14) is adapted to bring the means forming lock (16) into the unlocked position when loading tube (13) is moved away from chamber (17), and is mounted on loading tube (13).

Abstract: The invention relates to a breech wedge for artillery cannon, of a type that includes means for supporting a primer-cartridge magazine that is driven in translation and rotation under the control of an assembly consisting of a rack and pinion. This first pinion is mounted on a shaft supporting a second pinion, which cooperates with a second rack integral with a fork sliding on the wedge. A control lever pivots on the breech sleeve and supports a roller, which cooperates with a groove in the fork in such a way as to slide the fork on the breech wedge. A second roller cooperates with a groove in the wedge in such a way as to cause the wedge to slide on the breech sleeve.
