Abstract:
A method for acquiring the coordinates of a trigger point of a projectile above a field part on which a target is located, including: emission of at least one laser pulse having a pre-determined duration and directed towards the target; reception of the images reflected with a receiver equipped for the synchronous visualization of the laser pulses originating from a piece of observation of the field part; recovery of the coordinates of a desired trigger point when the operator has chosen a location after the piece of observation was moved. The invention also relates to a fire-control system using such a method.
Abstract:
The invention relates to a movable artillery gun comprising: a frame supporting a turning plate, turning plate comprising a first pivot link of a vertical axis, turning plate comprising at least one turning motor means for rotating a turning interface around the first pivot link, the turning interface supporting a firing carriage and comprising a fine traverse laying means allowing the carriage to rotate with respect to the turning interface around a second pivot link of a vertical axis.
Abstract:
A method for acquiring the coordinates of a trigger point of a projectile above a plot of land on which a target is located, said method being characterized in that it includes the following steps: performing a three-dimensional acquisition of the plot of land using a laser observation means, constructing by calculation, and then displaying an image of the plot of land from a bird's eye view observation direction, and recovering the coordinates of the trigger point desired for the projectile after the positioning said area on the image of the land. The invention also relates to a fire control implementing such a method.
Abstract:
A system to access a passenger compartment, said system having a door hinged to a chassis frame by a first horizontal articulated joint and forming an inclined ramp, wherein said system comprises an actuator to move said door, linked to said door and said chassis frame, a step plate at least partially covering the outside of said door and hinged to said chassis frame by a second articulated joint parallel to said first articulated joint and with a hinge pin offset to the first articulated joint, said step plate linked to said door by a drive element connected to said door by a third articulated joint and to said step plate by a fourth articulated joint, the pins of said first through fourth articulated joints being parallel to one another and form the four summits of a parallelogram deformable between open and closed positions of said door.
Abstract:
An automatic reloading device for a weapon fed by two ammunition magazines includes first and second ammunition conveyors, each movable in phase opposition between a position for collecting a piece of ammunition from a magazine and a position for reloading the weapon. The automatic reloading device includes a single actuator, able to output an alternating motion, and movement devices for transmitting the alternating motion to the first and second ammunition conveyors and converting it into movements of the first and second ammunition conveyors for an alternating feeding of the weapon. A weapon system can include such an automatic reloading device.
Abstract:
A weapon system includes a recoiling mass and a cradle, the recoiling mass including a weapon barrel and a breech ring and translating relative to the cradle during firing, and a guide device being provided for guiding this recoil movement of the recoiling mass. This weapon system is characterized in that the guide device includes at least one bar that is secured to the cradle and extends to the rear of the weapon system, the bar cooperating with at least one rail carried by the breech ring. The breech ring is connected to the cradle by two pairs of hydraulic or pneumatic recoil brakes, each rail being arranged between two brakes of the same pair, the body of each brake being secured to the breech ring.
Abstract:
An aiming method for a weapon system including a weapon secured to a chassis, as well as an aiming device implementing such a method. The weapon system includes a computer having in an internal memory a nominal firing profile defined by the extreme elevation and relative bearing aiming instructions that are possible for the weapon, in the reference frame associated with the chassis, when the latter is in a firing position on a horizontal ground. The boundaries of the nominal firing profile are converted so as to determine a transformed firing profile which is delimited by the extreme directions of fire that are possible in the reference frame of the chassis when the latter is in the firing position on the field, and finally the operating firing profile is determined for the aiming, which is defined as the geometric intersection of the nominal firing profile and the transformed firing profile.
Abstract:
An anti-projectile protection device for an attachment means of a member attached to a wall of a structure includes a plate designed to be spaced apart from the attachment means and fixed directly or indirectly to the wall by means of deformable connecting tabs which are secured to the plate and on which engage connecting screws. The heads of the connecting screws are interposed between the plate and the tab in question and holes are created in the plate to allow the connecting screws to be tightened. The connecting tabs include notches such that the heads of the connecting screws can be engaged between the plate and the tab by simple translation of the plate when they are installed in their tapped holes. An inspection hatch also incorporates such a protection device.

Abstract:
A device for distribution of conditioning air for vehicle turret comprises at least one air duct sheath, the sheath comprising a chute adapted to be made integral with the vehicle and a shutter adapted to be made integral with the turret. The sheath is the form of an arch of circle coaxial with the rotation axis of turret. The device comprises at least one duct in the form of an arch of circle having the same average radius as that of the sheath and able to slide with respect to the sheath between a closed position in which the duct connects one end of the sheath to another end of said sheath, or to another sheath, for continuity of airflow between the sheaths, and an open position in which the duct is slid within the sheath so as to leave a passage transverse to the sheath along a circular sector.
