Definitions
- the technical field of the invention is that of large caliber base deflectors, large caliber weapons equipped with such deflectors, as well as methods for deflecting bases.
- the device comprises a flexible deflector formed of a curved plate, movable relative to the weapon, and which can be placed opposite the longitudinal axis of the weapon.
- the deflector is oriented so that a base ejected from the weapon hits the deflector which absorbs shock and deflects the base into a base bag located down below the turret bearing pivot joint. When the deflector is not in use, it is stowed away under the gun, along with the bag containing the previously ejected pellets.
- Such a deflector encroaches significantly on the volume surrounding the weapon.
- Such a size is not compatible with the cramped environments which may be encountered, for example in a turret of a vehicle, and in particular if the turret is located entirely above the parting line separating it from the chassis and therefore does not present no communication channel with the vehicle chassis.
- a base deflector which is integral with a cradle and comprises a panel disposed at a distance from a base ejection orifice.
- the panel is integral with a fixed part of the weapon and is therefore positioned behind the bolt at a distance which must be compatible with the recoil of the weapon.
- Such a deflector also encroaches on the volume surrounding the weapon and does not reduce the bulk.
- US Pat. No. 4,919,038 discloses a socket collector comprising a panel located at a distance from a socket ejection orifice in order to deflect its path.
- the panel must be placed at a considerable distance from the cylinder head and the volume required for such a device is large.
- the aim of the invention is to solve this problem of bulk.
- the invention relates to a base deflector intended to equip a weapon at the level of a base ejection orifice in the vicinity of a breech of the weapon, the deflector comprising a panel intended to be fixed by one of the guns. its edges relative to the weapon, deflector characterized in that the panel is fixed to the weapon by an articulation and in that it comprises an actuator capable of causing the panel to pivot between a deflection position where the deflector is positioned on the ejection path of a base in order to deflect it and a folded position where the panel is pressed in the vicinity of the cylinder head.
- the invention also relates to a large caliber weapon characterized in that it is equipped with a base deflector according to the preceding characteristic and in that the actuator is positioned on a rear face of the breech of the weapon.
- the panel has an articulation axis which is inclined at a first angle relative to a vertical plane passing through a longitudinal axis of the weapon.
- the plane of the panel is inclined at a second angle relative to the longitudinal axis of the weapon.
- the first and the second angle are substantially equal to 45 °.
- the axes of the ends of the actuator are never aligned with the hinge axis of the panel.
- the cylinder head has a boss intended to prevent the alignment of the axes of the ends of the actuator and of the articulation axis.
- the invention also relates to a method allowing the deflection of a base ejected from a weapon according to the invention, characterized in that: the panel is placed in the deflection position when the weapon has just returned to battery; the panel is placed in the folded position approximately one second after opening the breech.
- FIG. 1 shows a detail view of a deflector according to the invention
- FIG. 1 shows a detail view of a weapon equipped with a deflector according to the invention in a folded position
- FIG. 1 shows a detail view of a weapon equipped with a deflector according to the invention in a deflection position
- FIG. 1 represents a schematic view of a turret comprising a deflector according to the invention.
- a deflector 1 according to the invention comprises a substantially planar panel 2 which has a hinge 3 on one of its edges and which connects it to a rear face of a breech 101 of a weapon.
- the deflector also comprises an actuator 4 disposed laterally to the panel 2.
- the actuator 4 is constituted here by an electric jack provided with a rod T which is connected by a first pivot connection 4a to one end 2a of the panel, opposite the end carrying the articulation 3.
- the jack 4 is also connected by a second pivot link 4b to the breech 101 of the weapon.
- a large caliber weapon 100 comprises the breech 101 which is closed by a wedge 102, movable vertically.
- the deflector 1 according to the invention is located on a rear face of the breech 101 in the vicinity of an orifice 103 of the latter, orifice 103 intended for the placing of a munition and the evacuation of a base. after firing (ammunition and base not shown).
- connection of the panel 2 relative to the cylinder head 101 is effected by means of the articulation 3 whose axis 3a is inclined by a first angle ⁇ of approximately 45 degrees relative to a vertical plane P passing through the longitudinal axis X of the weapon.
- the deflector 1 is shown in the folded position, that is to say that the panel 2 is pressed as close as possible to the rear face of the cylinder head 101.
- the cylinder 4 has its rod T extended and it is substantially parallel to the rear face of the cylinder head 101.
- the device 1 is thus protruding as little as possible from the rear face of the cylinder head, which greatly limits the bulk. behind the gun. This space requirement due to the deflector 1 is at most equal to the maximum thickness E of the cylinder 4.
- the cylinder head 101 has a boss 9 which prevents the alignment of the axes 4a and 4b of the pivot connections of the cylinder 4 and of the axis 3a of the articulation 3.
- the boss 9 may optionally include a spring plunger 9a which acts against the folding action of the panel 2, in order to facilitate positioning which tends to return the panel 2 to its deflection position.
- boss 9 and the pusher 9a can be carried by the panel 2 itself. But this variant would impose an additional mass on the panel 2 and the solution of positioning the boss 9 on the cylinder head 101 is therefore preferred.
- this folded position also makes it possible to minimize the space occupied by the deflector 1 behind the breech 101, allowing reloading and recoil of the weapon without interference from the deflector 1 with any surrounding equipment.
- the weapon has just returned to battery after firing.
- the return to the battery comprises a return movement from the wedge 102 of the breech to its initial position and it is ensured by the action of elastic links (links not shown ) which restore part of the recoil energy.
- the panel 2 of the deflector 1 is pivoted by the cylinder 4 which, by retracting its rod T, will position the panel 2 opposite the orifice 103, on a first ejection path of the base, with an angular orientation ⁇ of the plane P2 of the panel relative to the longitudinal axis X of the weapon 100 (schematically shown in Figure 3 a main direction of the plane P2 parallel to an edge of the panel 2).
- the base is ejected from the cylinder head 101 by spring means well known to those skilled in the art (base and spring means not shown).
- FIG. 4 thus shows a turret 20 of a military vehicle which comprises a weapon 100 whose breech 101 is equipped with a deflector 1 whose panel 2 advantageously makes it possible to deflect the bases C towards a receptacle 10 with bases which is placed in the turret. 20, above a parting line 40 of the turret 20 with a chassis 30 of the vehicle.
- the arrow ⁇ schematizes the trajectory of the ejected pellet.
- deflector 1 is returned to the stowed position, freeing access to the weapon chamber. This delay of at least one second is considered necessary to allow the ejection of a pellet under good conditions and this without slowing down the placing of a new projectile in the weapon.
- the invention therefore makes it possible to solve the problem of bulkiness in the rear part of a weapon breech as mentioned in the preamble, but it also makes it possible to avoid any intrusion below the turret joint plane.
