Definitions

• the technical sector of the present invention is that of devices for protecting a target attacked by a projectile.
• the attacking projectile is very often a missile but can be of any type, for example an arrow projectile, a projectile with formed or hollow charge, etc.
• the patent FR-A-2 722 873 describes a protection system comprising a mobile launching container in site and in deposit controlled by a detection system making it possible to control the firing of a defensive projectile from the container.
• a defensive projectile constituted by a flash grenade.
• a patent DE-3,410,467 is also known which proposes a defensive projectile constituted by a flash charge to disturb the attacking missile.
• Patents US-5229540, US-4765244 and FR-2458044 describe defense systems against aggressive missiles consisting in launching a defensive projectile against them.
• conventional means of orientation in site and in deposit similar to those used to orient a gun or launcher are used.
• the barrel is mobile in site by relative to a turret or support and that this turret is movable in bearing with respect to the target.
• This architecture is well known for orienting the cannon in all directions of space.
• the disadvantage of these systems lies in the fact that they cause a modification of the silhouette of the target making it better detectable by the aggressor and therefore more visible and more vulnerable.
• the object of the present invention is to provide a defense system integrated into a target to be protected and giving it a more compact appearance.
• the subject of the invention is therefore a system for defending a target against an attacking projectile of the type comprising a device for launching defensive projectiles and means for controlling the device after detection of the attacking projectile, characterized in that the launching device comprises a mobile cupola in relation to the target and a launcher integral with the cupola and articulated in site in the cupola deposit to ensure compactness of the assembly relative to the target.
• the launcher is mounted articulated at its base around an axis integral with the cupola.
• the cupola is in the form of a circular base delimiting a side wall whose height is less than half of its outside diameter.
• the launcher is actuated in rotation by a jack arranged in the internal space delimited by the side wall, secured to one end of the cupola and the rod of which is secured to a lever extending the base said launcher.
• the rod of the jack is parallel to the plane (PI) of rotation in the deposit of the cupola.
• the launcher is articulated in elevation at an angle between about -10 ° and + 70.
• the length of the launcher is substantially equal to the diameter (d) of the cupola.
• the launcher comprises at least two launching tubes arranged side by side.
• the cupola is actuated in rotation of the deposit with respect to the target using a pinion rack assembly, the pinion being integral with the cupola.
• the rack is integral with the control means comprising a double-acting cylinder whose piston is actuated by a hydraulic group.
• the axis of the piston is substantially parallel to the plane of rotation in the deposit.
• a very first advantage of the system according to the invention lies in the fact that the cupola and the launcher form a unitary unit which can be integrated into any type of target.
• Another advantage lies in the fact that the external dimensions of the unit assembly are compatible with the environment of a battle tank.
• Another advantage lies in the fact that a target can be equipped with several systems according to the invention.
• FIG. 1 represents a general view of the launcher device
• FIG. 2 is a side view of the launcher positioned on its support shown in section
• FIG. 3 is a vertical section of the cupola showing the means of rotation in elevation and in deposit
• FIG. 4 illustrates the drive means in the cupola deposit
• FIGs 5 to 7 illustrate the positions in negative, zero and positive site of the launcher.
• FIG 1 there is shown a general view of the launcher device 1 according to the invention, the control means after detection of an attacking projectile is not shown. Indeed, this system is known in itself and can be constituted by an embodiment as disclosed by the patents cited above.
• a preferred application of the invention consists in equipping a combat tank with one or more cupolas fixed either on the chassis or on the turret.
• the device as shown in this figure can be integrated into any target that needs to be protected by providing a circular fitted with a bearing. It includes a cupola 2 in the form of a base 3 of circular symmetry whose cylindrical side wall is only visible. This base 3 is generally flattened, whose height is small compared to the diameter to delimit a receptacle intended to receive site control means. As an indication, the height of the base can be less than the radius.
• This base receives on the upper side a launcher 4 comprising two tubes 5 and 6 for launching defensive projectiles, connected together.
• the tubes 5 and 6 are oriented in the same direction, that is to say that their firing axes are parallel.
• the launcher 4 is articulated in elevation relative to the base 3 around the pins 7, the ends of which are fixed along a sequence.
• the hydraulic block 8 located in the receptacle below the launcher 4 for controlling its rotation in elevation.
• a control means 9 ensures the rotation in bearing of this base relative to the target in relation to a hydraulic block 10.
• the cupola 2 can be equipped with a larger number of tubes, for example from 3 to 6. It is preferable that the firing axes of these tubes are parallel to each other to maintain the compactness of the assembly. Thus, if three tubes are provided, we will arrange for the three axes of fire to be in the same plane.
• FIG 2 there is shown a view of the device 1 placed on a support 11 forming part of the target.
• the cupola 2 is rotatably mounted relative to the support 11 by means of a bearing 12.
• the latter is provided with a shaft 13 aligned with the axis 14 of the bearing 12.
• the shaft 13 is provided with a pinion 15 cooperating with the control means 9.
• the launcher 4 is provided at its bottom wall 16 of means for receiving the pins 7 to ensure rotation about the axis 17. This axis is located below and outside the launcher. This arrangement ensures the site rotation of the launcher in the cupola deposit.
• FIG 3 there is shown in section the means of site control and deposit of the device.
• the launcher 4 is provided with a lever 18 fixed at its base and whose free end extends beyond the axis 17 of rotation.
• the base 3 is provided in its receptacle with a jack 19 whose rod 20 is fixed to the free end 21 of the lever 18 and whose body is fixed by an articulation 22 to the base.
• the jack 19 is in relation to the hydraulic block 8 to ensure its operation.
• FIG. 4 illustrates the embodiment of the control means 9 which is rigidly fixed to the target 11 by two yokes 23 and 2.
• This means is in fact a double-acting cylinder whose body 25 receives a rod 26 which supports a rack 27 engaging the pinion 15.
• This body defines two lateral chambers 28 and 29 in which the ends of the rod form the pistons 30 and 31 whose sealing in the respective chambers 28 and 29 is ensured in a conventional manner. Between the chambers 28 and 29 is provided a free space intended for the movement of the rack 27.
• the chambers 28 and 29 are respectively supplied with fluid through the orifices 32 and 33 by the hydraulic block 10.
• the rod 26 is brought back to the right, that is to say that the chamber 29 is emptied by the orifice 33 while the chamber 28 is filled by the orifice 32.
• the rack 27 is actuated in following translation a back and forth movement by ordering the filling of one of the two chambers for rotating the pinion 15 and therefore the rotating cupola.
• the rack 27 can occupy all the intermediate positions to orient the cupola in the deposit according to the position desired by the user.
• FIGS. 5 to 7 three positions in elevation of the launcher 4 have been shown following the actuation of the jack 19.
• Figure 5 illustrates the maximum negative site of approximately -10 °. It can be seen that the lever 18 is pushed back in the vicinity of the internal lateral wall of the base 3 and that the rod of the jack 19 is in the maximum extension position.
• PI be the bearing plane
• P2 the plane parallel to PI passing through the point of articulation of the lever. If the plane P3 is defined as being the plane parallel to PI passing through the point of articulation of the lever 18 parallel to the plane PI, the end of the rod of the jack is then above the plane P2 close to the plane of bearing PI .
