Definitions
- the technical field of the invention is that of projectile firing systems and in particular missile launcher boxes (or pods) mounted on a platform, for example a vehicle.
- Projectile firing systems having a housing containing at least one projectile are well known. These systems are mounted on a platform, such as a vehicle, and they allow the pointing and firing of one or more projectiles such as missiles or rockets.
- the hatch is intended to open by pivoting around a site axis by means of a motorized means to allow firing of the projectile or the replenishment of the box with one or more new projectiles.
- the motorized opening of the hatch requires powering the firing system to be able to activate the opening of the hatch.
- the opening in site of the hatch is not always favorable to the accessibility of the end of the box, in particular when it is located in superstructure of a vehicle.
- the invention aims to simplify replenishment operations of a firing system by not imposing power on the firing system.
- the invention relates to a projectile firing system, in particular a missile launcher, comprising a caisson which is intended to contain at least one projectile and one end of which is closed by at least one hatch, a hatch which is articulated by one of its sides relative to the casing by means of a first hinge, a firing system characterized in that the hatch comprises an opening which is articulated with respect to the hatch with a second hinge oriented perpendicular to the first hinge.
- the first hinge allows pivoting of the hatch around a horizontal axis.
- the firing system comprises a motor means for pivoting the hatch around the first hinge.
- the hatch comprises an L-shaped frame on which is articulated the opening.
- the opening comprises a lock intended to prevent the pivoting of the second hinge.
- the opening comprises a holding means in the open position for locking the opening perpendicular to a plane of the hatch.
- Figure 1 shows a three-quarter view of a firing system according to the invention fixed on a vehicle turret.
- Figure 2 shows a detail view of the firing system with a hatch in the closed position and its opening also closed.
- FIG. 3 shows a detail view of the firing system with a hatch in the open position, the opening integral with the hatch being closed.
- Figure 4 shows a detailed view of the system shot with a hatch in the closed position and the hatch opening in the open position.
- a turret 200 of a vehicle 100 is armed with a firing system 1 disposed on one of the side and vertical walls 201 of the turret 200.
- the firing system 1 is orientable in site with respect to the wall 201 around a site axis 101 by means of electrical pointing means or hydraulic (pointing means not shown).
- the bearing orientation of the firing system 1 is by pivoting the turret 200 about a bearing axis 201 and relative to the chassis of the vehicle 100.
- the firing system 1 comprises a caisson 2 which according to the illustrated embodiment has a square profile.
- the caisson 2 is intended to contain at least one projectile, here a missile 8, and it thus forms a launch tube for this missile.
- the rear AR of the box 2 ( Figure 1) is closed by a hatch 3 having on its upper side a first hinge 4 whose axis is parallel to the axis of site 101, so here substantially horizontal.
- the hatch 3 carries an opening 5 which here has a square shape of dimensions slightly smaller than those of the square shape of the hatch 3 and which is fixed to a part of the hatch 3 which forms a frame 3a and which is L-shaped. .
- the frame 3a thus comprises a horizontal upper bar 3al carrying the first hinge 4 and a lateral bar 3a2 which is vertical and which carries a second hinge 9 on which is fixed the opening 5.
- a latch 6 allows to make the opening 5 and the frame 3a, thus preventing the opening by pivoting the opening 5 relative to the hatch 3.
- Sealing means between the frame 3a and the opening 5 will be provided, for example deformable joints.
- the thickness of the opening 5 will advantageously be the same as that of the frame 3a.
- a motor means 7, such as an electric or hydraulic jack, can be implemented provided that the energy servitudes of the firing system 1 are activated (power up the firing system).
- the cylinder 7 allows, during the operating phases of the firing system, the opening in the upward position of the hatch
- motor means conventionally known to those skilled in the art would be possible.
- an electric motor associated with a gear train or with pulleys and a belt or sprockets and a chain may be used as a motor means 7 for opening and closing the hatch 3.
- the hatch 3 is sufficiently open so as to be clear of the trajectory of the propellant jet of the missile 8, which jet is ejected by the nozzle of the latter (propulsion jet not shown).
- the box 2 can be oriented in situ without risk of interference with vehicle elements located downward, such as the roof for example.
- the lock 6 may be a manual operation lock conventionally known to those skilled in the art such as the lock described in the patent IT7921144 for example. It may include a key lock to block access to the contents of the box 2. Means for holding in the open position (for example a forestay set up manually) may be added to the opening to block the opening in this last position and prevent its closure during reloading of the tube 2 (holding means in position not shown).
- the invention allows a replenishment of the caisson 2 without having to start the energy servitudes of the firing system 1 and therefore without the need to actuate any motor means.
- a servant can simply open the opening and reload the box 2.
- the opening of the opening 5 being around a vertical axis, the maneuver of this opening is facilitated compared to that of the hatch itself which, once opened, forms an obstacle limiting access to the box.
