Definitions

  • the technical field of the invention is that of projectile firing systems and in particular missile launchers (or pods) mounted on a platform, for example a vehicle.
  • Projectile firing systems comprising a box containing at least one projectile are well known. These systems are mounted on a platform, such as a vehicle, and they allow the aiming and firing of one or more projectiles such as missiles or rockets.
  • the hatch is intended to be opened by pivoting around a site axis by means of a motorized means to allow the firing of the projectile or else the resupply of the box with one or more new projectiles.
  • the motorized opening of the hatch requires that the firing system be energized in order to be able to activate the opening of the hatch.
  • the opening in elevation of the hatch is not always favorable to the accessibility of the end of the box, in particular when the latter is located in the superstructure of a vehicle.
  • the invention aims to simplify the operations for restocking a firing system by not requiring that the firing system be powered up.
  • the invention relates to a projectile firing system, in particular a missile launcher, comprising a housing which is intended to contain at least one projectile and one end of which is closed off by at least one hatch, which hatch is articulated by one of its sides relative to the box thanks to a first hinge, firing system characterized in that the hatch comprises an opening which is hinged relative to the hatch thanks to 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 motor means allowing the hatch to pivot around the first hinge.
  • the hatch comprises an L-shaped frame on which the opening is articulated.
  • the opening comprises a lock intended to prevent the pivoting of the second hinge.
  • the opening comprises a means for maintaining in the open position intended to block the opening perpendicular to a plane of the hatch.
  • a turret 200 of a vehicle 100 is armed with a firing system 1 arranged on one of the lateral and vertical walls 201 of the turret 200.
  • the firing system 1 is orientable in elevation relative to the wall 201 around a site axis 101 by means of electrical or hydraulic pointing means (pointing means not shown).
  • the orientation in bearing of the firing system 1 is effected by the pivoting of the turret 200 about a bearing axis 201 and relative to the chassis of the vehicle 100.
  • the firing system 1 comprises a box 2 which according to the illustrated embodiment has a square profile.
  • the box 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 box 2 ( figure 1 ) is closed off by a hatch 3 comprising on its upper side a first hinge 4 whose axis is parallel to the site axis 101, therefore here substantially horizontal.
  • the hatch 3 carries an opening 5 which here has a square shape with 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 3a1 carrying the first hinge 4 and a side bar 3a2 which is vertical and which carries a second hinge 9 on which the leaf 5 is fixed.
  • a lock 6 makes it possible to make the opening 5 and the frame 3a integral, thus preventing opening. by pivoting of the opening 5 relative to the hatch 3. Sealing means between the frame 3a and the opening 5 will be provided, for example deformable seals. 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 cylinder, can be implemented on condition of activating the energy easements of the firing system 1 (switching on the firing system).
  • the jack 7 allows, during the operating phases of the firing system, the opening in elevation of the hatch 3 by pivoting the latter around the first hinge 4.
  • motor means conventionally known to those skilled in the art would be possible.
  • an electric motor associated with a gear train or else with pulleys and a belt or pinions and a chain could be used as motor means 7 to open and close the hatch 3.
  • the hatch 3 is sufficiently open so as to be clear of the path of the propellant jet of the missile 8, which jet is ejected by the nozzle of the latter (propellant jet not shown).
  • the box 2 can be oriented in elevation without risk of interference with elements of the vehicle located downwards, such as the roof for example.
  • the hatch 4 is closed but the opening 5 is opened by pivoting around the second hinge 9, which is integral with the side bar 3a2 of the hatch 3 and arranged perpendicular to the first hinge 4.
  • the lock 6 may be a manually operated lock conventionally known to those skilled in the art such as the lock described in the patent. IT7921144 for example.
  • a means of holding in the open position may be added to the opening in order to block the opening in this opening. last position and prevent its closing during reloading of the tube 2 (means for maintaining in position not shown).
  • the invention allows the box 2 to be replenished without having to start the energy easements of the firing system 1 and therefore without requiring the actuation of any motor means.
  • a servant can simply open the door and reload box 2.
