Abstract:
A gripping device for shells that includes a pair of jaws intended to clamp a shell, each jaw being able to pivot towards a closed position obtained by applying the top end of each jaw to the shell. A locking means links the top ends of the jaws and includes two connecting rods and a central segment linking these connecting rods. The connecting rods are articulated relative to the jaws by a first articulation and by a second articulation to the central segment. A spring links each first articulation to a central point of the segment. A movable stop situated above the locking means is capable of pushing the locking means downwards until it is below an unstable equilibrium position of the locking means.
Abstract:
A housing intended to be arranged on a vehicle, in particular a military vehicle, and having a substantially parallelepiped shape including a front wall and a rear wall that each includes at least one bore for allowing air to flow inside the housing. At least one of the front or rear walls carries a plate, arranged outside the housing and at a distance from said wall, the housing further including at least one first slot allowing air to pass between the plate and the wall in question, and at least one second slot constituted by the gap between a lateral edge of the plate and said wall. The invention also concerns a weapon system including at least one missile launcher arranged in such a housing.

Abstract:
A belt ammunition feeding device for a dual-feed automatic weapon includes, for each feeding channel, at least a first rigid chute leading an ammunition belt from a magazine to the weapon, and a second rigid guide chute arranged at each tilting arm, the second chute including an upper mouth arranged opposite the outlet opening of the first rigid chute, the mouth also including a flared part forming a guide funnel and making it possible to cap the outlet opening of the first rigid chute when the tilting arm is in its engaged position with a stationary positioning star.

Abstract:
A jaw pivoting about an axis for clamping the shell, a lower end of the jaw receives the shell to allow closure. The notch intended to interfere with a catch of a cam to retain the jaw in the closed position. The cam is rigidly connected to a pivoting lever which allows the catch to be moved from the path of the notch to allow the jaw to open. The lever is to be pivotally activated through the force of an external component. The device includes a first and second spring each acting on the lever in an opposing manner, the second spring being stiffer than the first spring. The effect of the first spring is to lift the lever. The second spring counters the action of the first spring in order to delay the lifting of the lever and the catch when removing the component.
Abstract:
A method for assisting the location of a target for a first user equipped with an observation device includes an augmented reality observation device associated with a first user reference frame. According to this method, a reference platform associated with a master reference frame is positioned on the terrain, the reference platform is observed from at least one camera worn by the first user, the geometry of the observed platform is compared with a numerical model of same and the orientation and location of the first user reference frame is deduced with respect to the master reference frame. It is then possible to display, on an augmented reality observation device, at least one virtual reticle locating the target.
Abstract:
An infrared camouflage device and a vehicle including such a device which includes an array of parallel pipes carrying a heat-transfer fluid for changing the thermal signature of a vehicle. This device is characterized in that it includes an inlet manifold, an intermediary manifold, a first series of first pipes connecting the inlet manifold to the intermediary manifold, a second series of second pipes connecting the intermediary manifold to an outlet manifold, each first pipe being located in the vicinity of a second pipe so as to form, at the device, an alternation of first and second parallel pipes, the inlet manifold and the outlet manifold being in the vicinity of each other.
Abstract:
An adaptive masking method for an element in a field of operations. According to this method, at least one cover allowing to cover the element is implemented, the cover carrying at least one image generator network connected to an image synthesizer coupled to a camera. According to this method, the camera is positioned so as to cover both a portion of a background of the element and the entire cover, the image synthesizer controlling the at least one image generator network so as to minimize the contrast and optionally the frequency deviation between the background and the cover. The device implementing such a method is described.
Abstract:
A body shell of an armoured vehicle includes a front face carrying an armoured windscreen projecting towards the outside of the body shell, at least one side wall including an opening, said side wall being integral with the front face at a strut which is defined by a part of the side wall included between an edge of the opening and a rim of the side wall situated furthest outwards at the front of the vehicle. In the armoured vehicle body shell, the strut extends beyond the front face towards the outside of the body shell, and at least one edge of the opening is situated near the front face, so that the junction between the strut and the front face of the vehicle is at the vicinity of the edge of the opening which forms a rear edge of the strut.
