Definitions
- the present invention relates to a device for protecting armored vehicle against kinetic effect projectiles.
- a device comprising a radar associated with a projectile launcher system, see for this purpose document FR-A-2 722 873.
- the radar detects the launching an enemy projectile, it activates the launcher system, which launches a projectile in the direction of the threat, this defense projectile being ignited in the immediate vicinity of the threat, which modifies the threat enough trajectory to make it ineffective.
- the launcher system must include a significant number of launchers.
- the subject of the present invention is a device for protecting a vehicle, in particular an armored vehicle, against projectiles, in particular of kinetic effect projectiles, a device which provides protection optimal in the greatest number of directions, while requiring the minimum possible launchers.
- the device according to the invention comprises at least one launcher device whose movements in at least one plane are controlled by a pyrotechnic cylinder.
- the present invention is described above with reference to a device for protecting a vehicle, in particular a tank, against kinetic effect projectiles, but it is understood that it is not limited to this single application, and that it can be implemented in the protecting a vehicle from other types of threats, or even it can be implemented for attacking targets, in particular targets high speed mobiles;
- FIG. 1 Schematically shown in Figure 1 a device 1 of tank protection according to the invention.
- This device 1 comprises essentially a launcher tube 2 fixed by its rear part to the structure 3 of the tank by a joint 4, for example of the ball joint type.
- Site orientation or in the direction of the tube 2 is provided by a pyrotechnic cylinder 5 connected to the tube 2 by a joint 6 and to the structure 3 by another joint 7, these two joints 6,7 being for example also of the ball joint type.
- the cylinder 5 has been shown in the non-activated position in (position "low” of the tube 2), and in the activated position in figure 2.
- the piston of this jack is in abutment against the flat wall, called anterior, of the cylinder opposite to that, called posterior, against which it was in stop in non-activated position.
- a 2A ammunition is placed in the tube 2, ready to launch.
- FIGS. 3 and 4 The construction details of the jack 5 have been illustrated in FIGS. 3 and 4, which is respectively represented in the non-activated position and in the position activated.
- This cylinder 5 essentially comprises a cylinder 8 in which is displaces a piston 9.
- An axial rod 10 is formed integrally with the rear wall 11 of the cylinder or fixed to it), and an axial rod 12 is formed integrally with the piston 9 (or fixed to it) and passes through a neck 13 formed on the front wall 14 of the cylinder 8.
- the piston 9 is provided with sealing means 15, an O-ring for example, ensuring its tightness in relation to cylinder 8.
- a pyrotechnic charge 16 In a bowl formed in the face inside the wall 11, there is a pyrotechnic charge 16, and a initiator (detonator) 17 is housed in the wall 11, in contact with the charge 16. Conductors 18 connect the initiator 17 to an electrical device for appropriate control (not shown). A passing pin 19 diametrically through the neck 13 and the rod 12 immobilizes the latter in unactivated position of piston 8, and it can be easily broken when load 16 is activated. The piston can then come into abutment against the wall 14 ( Figure 4).
- FIG. 5 shows a jack 20 with three positions: a non-activated position (that shown in the drawing) for which the piston is substantially in the middle of the length of the cylinder, and two positions activatable (in abutment against either end of the cylinder) including one only can be activated at a time.
- the cylinder 20 essentially comprises a cylinder 21 closed at each of its two ends by a transverse partition 22,23 respectively.
- the partition 22 is integral with an axial rod 24.
- a piston 25 is arranged in the cylinder 21, and it is provided with sealing means 26 by compared to this cylinder.
- An axial rod 27, integral with the piston 25, passes through the wall 23 and its neck 28. In the non-activated state, the piston 25 is held in middle position by a pin 29 diametrically crossing the neck 28 and the rod 27.
- each of the internal faces of the walls 22,23 we practice a bowl, for example of annular shape, in which there is a pyrotechnic charge, respectively 30.31.
- Each of these charges is associated with an initiator respectively 32.33, housed in the wall corresponding 22.23.
- Conductors 34.35 connect the initiators 32.33 respectively to an appropriate control device (not shown).
- the rods 24 and 27 are connected one to the starter tube and the other to the structure of the tank, similar to that shown in Figures 1 and 2. According to the desired movement of the launcher relative to its non-activated position (piston at middle of the cylinder), i.e. depending on whether you want to shorten or lengthen the connection comprising this jack, one controls the firing of one or the other charges 30.31.
- the launcher tube 37 (making part of a set of several tubes arranged on a tank) is controlled by two cylinders 38,39, which can be of the type of Figures 1 to 4 or that of Figure 5.
- the axis of the cylinder 38 is vertical, and therefore makes it possible to orient the tube 37 in elevation, while the axis of the jack 39 is horizontal, and allows to orient the tube 37 in azimuth.
