Definitions

  • the technical sector of the present invention is that of fire lines fitted to combat vehicles, such as armored vehicles. tanks. etc.
  • the shooting function directly combines two sub-functions: - the intended function, - the fire function (weapon + ammunition).
  • firing control The subassemblies which perform the firing function and which contribute directly to its performance are commonly called firing control.
  • Aiming systems can be classified into two families: - the mask sights attached to the weapon, - the roof finders linked by an electrical or mechanical copy to the weapon.
  • the first class of sights is fitted to a large part of the fleet of battle tanks. They exist in different versions.
  • the equipment of the shooter of these vehicles is limited to a mask telescope (linked to the barrel) whose only "fire control" is limited to a engraved micrometer indicating the ballistic corrections to be made depending on the nature of the ammunition and the firing distance.
  • the object of the present invention is therefore to propose a fire control, for equipping combat vehicles provided with a mask telescope, ensuring both the stabilization of the line of sight and the laser telemetry.
  • the invention therefore relates to a firing line adaptable to a mask scope of a combat vehicle, of the type comprising in particular a stabilized mirror, a telemetry laser, and an electronic control unit, characterized in that it includes a housing welded to the turret mask enclosing the stabilized mirror inclined with respect to the horizontal so as to reference the line of sight passing through the mirror with respect to the axis of the trunnions of the weapon and the firing axis, the laser being arranged to surround its emission and reception beams along the sighting axis of the telescopic sight and the stabilized sighting axis.
  • the firing line comprises an optical unit arranged between the stabilized mirror and the telescope, consisting of a semi-transparent blade, a dichroic blade and a mirror to ensure the harmonization of the laser emission and reception beams with the scope of the telescope.
  • the dichroic blade is fixed and inclined at 45 ° on the line of sight of the telescope and the mirror is situated in a plane substantially perpendicular to that of the dichroic blade, the blade and the mirror being capable of ensuring the reflection of the emission beams and receiving the laser.
  • the mirror is movable in elevation and in bearing so as to compensate for differences in harmonization between the laser emission and reception axes with the sighting axis of the telescope.
  • the laser is provided with a reticle injected along the reception path into the telescope via the dichroic blade and a cube corner having its base transparent at 45 ° relative to the dichroic blade and placed on the optical path. to receive the beam from the dichroic blade, the blade being on one side transparent in the visible and on the other reflective in order to bring the image of the reticle along the line of sight of the telescope.
  • the dichroic plate is treated on the one hand on one side to reflect the wavelength of the laser and transmit the visible, and on the other hand on the other side to partially reflect the visible radiation.
  • the housing is in the form of a frame in which support slides are engaged by sliding inside thereof.
  • the laser is mechanically connected to the housing according to a mechanical reference defined with respect to the axis of the weapon's journals and to the firing axis.
  • An advantage of the present invention lies in the fact that, for the first time, it is possible to ensure observation and shooting on the fly with a mask scope without mechanical or optical modification thereof.
  • Another advantage lies in the fact that the adaptation of the device according to the invention to a mask telescope only results in a modification of the optical path of the image of the landscape entering the telescope, while allowing the aiming and the shooting using the telescope.
  • the device according to the invention is in the form of a kit adaptable to any type of mask lens, and this, for an advantageous cost.
  • FIG. 1 shows the turret 1 of a combat vehicle equipped in particular with a cannon 2, carrying a mask 3.
  • This turret comprises a riflescope not visible in this drawing, the aiming axis of which is parallel to the firing axis 31, that is to say the axis of the barrel 2.
  • the device according to the invention is integrated in a housing 4 fixed to the mask 3 by welding, with a copy of the axis 30 of the barrel journals and the firing line.
  • the harmonization of the aiming and shooting axes will be explained in more detail in relation to FIG. 2.
  • the housing is provided on its front face with closing flaps 5 making it possible to obstruct one of the aiming tracks.
  • FIG. 2 is a diagram illustrating the optical structure of the firing line according to the invention and partially that of the telescopic sight 6 whose aiming axis is referenced at 7 with its aiming reticle 8 and the focusing lens 9.
  • the device according to the invention comprises a stabilized mirror 10 adjustable in elevation and in bearing and delimiting the stabilized aiming axis 11 and a blade 12 ensuring on the one hand, the reflection of the stabilized aiming axis 11 on the axis scope 7 of the telescope and secondly the transmission of the line of sight 7 to the target.
  • the strip 12 is of the semi-reflecting type. In this stabilized aim, a laser path is used to measure the distance from the target and inject the value obtained into a shooting computer not shown in this figure.
  • the laser path comprises a laser 13. the emission path 14 of which is directed at the target by a first mirror 15. a second mirror 16, a dichroic blade 17. the blade 12 and the stabilized mirror 10.
  • Each of these optical elements causes a 90 ° reflection of the light beam and these are processed to reflect the 1,060 nm wavelength of the laser beam.
  • the mirror 16 is mounted movable so as to provide an adjustment range in elevation and in bearing.
  • the emission path 14 of the laser also includes an emission afocal 24 to limit the divergence of the beam, consisting of a diverging lens followed by a converging lens.
  • the reception channel 18 reaches the laser 13 via the stabilized mirror 10, the blade 12, the dichroic blade 17, the second mirror 16 and the dichroic cube 19. Between the cube 19 and the second mirror 16 is placed a converging reception lens 20 and collimation whose role is to collect the laser flux in return and to collimate the laser reticle to infinity. Between the laser 7 and the cube 19, a converging lens 21a and a field diaphragm 21b are successively placed to limit the laser reception field. The mirror 10, the blade 12, the dichroic blade 17, the mirror 16 and the cube 19 provide reflections at 90 ° from the reception channel.
  • a reticle 22 said laser reticle, is etched, which is injected by the diode 23 into the laser reception path 18.
  • This reticle 22 is lit from the rear and follows the reception path 18 by crossing the dichroic strip 17.
  • the beam is then taken up by a cube corner 25, and after a double reflection, emerges parallel to the incident beam. It is then reflected by the dichroic blade 17 towards the lens 9 and focused in the event of agreement on the reticle 8 of the telescope 6.
  • the mirror 16 is controlled in elevation and in bearing to bring the image of the laser reticle 22 onto the image of the reticle 8 .
  • the telemetry information is sent by an electrical link in an electronic control box of known type (not shown) arranged inside the combat vehicle.
  • FIG. 3 there is shown the mechanical structure incorporating the device according to the invention which is mounted in the housing.
  • the optical elements described in relation to FIG. 2 are fixed therein in a conventional manner according to the arrangement described.
  • the laser 13 is fixed on a plate 26 also receiving a casing 27 containing the optical elements for laser emission and reception (15,24, 21a, 21b, 19, 20).
  • the plate 26 and the casing 27 are integral with the internal structure of the housing comprising the slides 4a, 4b and 4c. These slides are engaged by sliding inside the housing, while copying the mechanical references of this housing.
  • the front slide 4a of the housing reveals the stabilized mirror 10.
  • the laser 13 is powered by the electric cable 28, which is connected to the electric sources of the combat vehicle.
  • the electrical connection emerges at the level of the mask 3 of the turret to penetrate inside the housing 4.
  • the button 29 for adjusting the mirror 16 making it possible to harmonize the laser paths with the telescopic sight reticle.
  • the procedure for harmonizing the firing axis 31 and the aiming axis 7 is known in itself and need not be explained.
  • the stabilization block consists of a mobile pointing mirror along two axes equipped with a gyroscope.
  • the viewfinder offers two ways: - the normal channel 11 which makes it possible to make observation and fire when stationary or in motion, the target being telemetric by the stabilized channel, - the emergency route 7 which corresponds to the normal line of sight of the telescope 6, compensates for the possible failure of the normal route. It allows observation and shooting only when stationary.
  • a protection filter can be attached to the optical path in front of the telescope 6.
