Definitions

  • the present invention relates to a zone defense mine of the type comprising an orientable launching tube for launching a projectile at any bearing angle and a monitoring system for detecting a target in the mine's effectiveness area, the projectile. containing at least one explosive charge, means for rotating the projectile about an axis thereof and means for detecting a target.
  • a zone defense mine makes it possible to attack a target, such as a tank, within a radius of a few tens to a few hundred meters, this radius sweeping a surface corresponding to the area of effectiveness or the operational scope of the mine.
  • the detection means on board the projectile sweep the entire effectiveness area of the mine.
  • the projectile is generally pulled vertically and rotated around a vertical axis, so that the projectile detection means sweep the ground along a curve, called an imprint, in the form of a spiral.
  • the mine is then used in short-range operating mode, that is to say that the mine's radius of action is a few tens of meters.
  • a mine with an omnidirectional attack system is notably described in document FR-2 641 071 which relates more particularly to a self-propelled projectile by means of an improved rocket engine.
  • the detection means on board the projectile scan only one sector of the mine's effectiveness area, so that the mine surveillance system must first determine the bearing angle of the target so that the projectile launch tube is oriented at this angle.
  • the projectile is generally fired at a given elevation angle between 45 and 60 °.
  • the projectile moves on a curved trajectory and its detection means scan the ground along a curve corresponding to the combination of a spiral and the projection on the ground of the vector velocity of the projectile.
  • the mine is used according to an operating mode at medium range, that is to say that the radius of action of the mine is of the order of a few hundred meters.
  • a mine of this type is notably described in document FR-2 607 585 where the projectile is self-propelled and rotated about the roll axis, and in document FR-2 646 232 where the projectile is self-propelled. propelled and rotated around an axis coincident with the launching axis of the projectile.
  • the object of the invention is to design a mine which can be used interchangeably in a short or medium range operating mode.
  • the invention therefore relates to a zone defense mine of the type comprising a launch tube and a system for monitoring the mine's effectiveness area to detect a target, the projectile being equipped with at least one explosive charge, means for rotating the projectile about an axis thereof, and means for detecting the target, characterized in that the launching tube is orientable according to at least two different elevation angles, and in that it includes a system for positioning the projectile in the launching tube so that the inclination of its axis of rotation relative to the vertical is the same regardless of the site angle selected.
  • one of the aforementioned elevation angles is close to 90 ° so that the projectile is fired vertically.
  • the other site angle is most often between 45 and 60 °, the choice of this angle being determined by the specific characteristics of the projectile, in particular those of its explosive charge, in order to obtain an optimum trajectory.
  • the launching tube is oriented along the two aforementioned elevation angles by the use of two different platforms.
  • the launch tube may include a shoe which has a central cavity forming a bearing surface for the projectile.
  • the positioning system comprises an indexing device for orienting the projectile as a function of the site angle chosen and a device for immobilizing the projectile relative to the sabot during the firing phase of the projectile.
  • the indexing device comprises a ball permanently urged by a spring to partially protrude into one of a plurality of housings, each housing corresponding to a given elevation angle
  • the device for immo - stabilizing the projectile relative to the shoe comprises a plurality of weights equal in number to that of housings, and a housing intended to receive in part one of the weights during the firing phase of the projectile, one of the weights being located housing look for each given site angle.
  • the positioning system also comprises guide means for guiding the ball to pass from one housing to another.
  • the shoe can be in two parts, the part being intended to support the projectile, and in that the positioning system is located at the interface between the two parts of the shoe.
  • a part of the shoe may consist of a body with a convex bottom wall, a housing central being provided in the rectangular face opposite the bottom wall to partially receive the projectile.
  • the other part of the shoe may consist of a cylindrical body which rests at the bottom of the launching tube, a central cavity being located on the upper face of the body and having an opening and a bottom wall of a shape complementary to that of the bottom wall of the body of the first part of the hoof.
  • the same projectile can be indifferently used in a mine with a short or medium-range operating mode, which in particular facilitates manufacturing, maintenance and logistics operations.
  • the mine 1 with zone defense as schematically represented in FIG. 1 comprises a platform 2 for bearing on the ground, a launching tube 3 supported by the platform 2 and a projectile 5 placed in the tube 3 to be fired to attack a target located in the efficiency area of mine 1.
  • the projectile 5 is ejected from the launch tube 3 by means of a propellant charge 6 located at the bottom of the tube 3.
  • the pyrotechnic boosters 12 are controlled after a delay determined by a safety and arming device of conventional type. This device integrated into the processing and control unit 13 is itself activated by the firing of the projectile 5.
  • the casing 8 of the projectile 5 is at least in two parts to accommodate all of the above elements.
  • the means for fixing the two parts to each other are not shown.
  • the projectile 5 rests on a shoe 15 housed inside the launching tube 3.
  • This shoe 15 is supported on the bottom wall 3a of the tube 3, and it has on its upper surface a central cavity 16 having the complementary shape d 'a spherical cap of the casing 8 and which serves as a bearing surface for the projectile 5.
  • the cavity 16 is deep enough for the projectile 5 to lodge there until neighborhood of its equatorial plane for example.
  • the projectile 5 is placed on the shoe 15 by means of a positioning system 20 which makes it possible to orient the axis of rotation of the projectile 5 along the vertical axis YY, l ' firing axis XX of the charge 9 then making an angle a with respect to this vertical axis YY.
  • the positioning system 20 is located at the interface between the projectile 5 and the shoe 15, and it comprises an indexing device 21 associated with an immobilization device 30 which has the function of immobilizing the projectile 5 relative to the shoe 15 at the start of the projectile 5 firing phase.
  • the indexing device 21 comprises an element such as a ball 22 which is freely received in an external radial housing 23 of the casing 8 of the projectile 5.
  • the housing 23 has towards its end opening outwards a frustoconical bearing 24 to retain the ball 22 while allowing it to protrude partly outside the casing 8 under the permanent stress of a spring 25 housed in the bottom of the housing 23.
  • the housing 23 is obtained after having pierced an orifice in the thickness of the casing 8 to allow machining of the frustoconical surface 24, the internal opening of the orifice then being closed by a plug 23a.
  • the part of the ball 22 which can project outside the casing 8 of the projectile 5 is intended to be received in one of several complementary housings provided on the surface of the cavity 16 of the shoe 15. There are as many housings as possible positions of the projectile 5 relative to the shoe 15.
  • Guide means 47 can advantageously be provided which allow relative rotation of the projectile 5 with respect to the shoe 15 along an axis normal to the vertical plane passing generally through the two housings 27a and 27b (i.e. the vertical plane passing through the two directions of possible firing of the projectile) to facilitate the relative positioning of the projectile 5 relative to the shoe 15.
  • These guide means 47 are for example a groove 48 with a circular bottom provided on the surface of the cavity 16 of the shoe 15 and which connects one to the other the two housings 27a and 27b. This groove 48 will receive and guide the ball 22 during its passage from one housing to another.
  • the device 30 for immobilizing the projectile 5 relative to the shoe 15 comprises two weights 31a and 31b mounted respectively in two external radial housings 32a and 32b of the casing 8 of the projectile 5. These two housings 32a and 32b are respectively located on the side and on the other side of the housing 23 of the ball 22.
  • a radial housing 33 complementary to the housing 32a and 32b is provided on the surface of the cavity 16 between the two housings 27a and 27b. This housing 33 is aligned along the firing direction of the projectile 5, that is to say it is located on the axis of the launching tube 3.
  • the housing 33 is located opposite the counterweight 31 a or 31 b.
  • Each housing 32a and 32b is closed by an element 35, such as a metal sheet for example, to retain the associated counterweight as long as the projectile 5 is not fired.
  • the launch tube 3 In a short-range operating mode (Figure 1), the launch tube 3 must be oriented vertically along the YY axis.
  • the operator responsible for setting up the mine 1 on the ground uses a platform 2 such as a hollow cylindrical body 40 having a bottom wall 41 and support feet 42 adjustable in height to take account field accidents.
  • the platform 2 Once the platform 2 is positioned vertically, the operator introduces the launching tube 3 into the body 40 of the platform 2 and then positions the projectile 5 inside the tube 3, orienting it so as to that the ball 22 of the positioning system 20 protrudes into the housing 27a of the shoe 15.
  • the projectile 5 is then in the position of FIG. 2.
  • the operator comes to attach a cover 45 around the outlet opening of the launching tube 3.
  • the cover 45 fixed everywhere conventional means to the tube 3 has a central opening 45a having a diameter greater than that of the casing 8 of the projectile 5.
  • This cover 45 has in particular the function of retaining the shoe 15 during the firing phase without preventing the ejection of the projectile 5.
  • the mine monitoring system 1 (known type system, for example acoustic or magnetic) has detected a target in the mine's effectiveness area, the projectile 5 is fired.
  • the propulsion charge 6 of the launch tube 3 is initiated by an igniter 6a.
  • the pressure of the gases resulting from the ignition of the charge 6 will cause the shoe 15 and the projectile 5 to be ejected simultaneously along the vertical axis YY.
  • the impulse printed on the shoe 15 is such that the counterweight 31 has opposite the housing 33 of the shoe 15 punctures the thin metal sheet 35 which retains it in its housing 32a.
  • the counterweight 31a a then engages in the housing 33 of the shoe 15 and thus makes it possible to immobilize the projectile 5 relative to the shoe 15.
  • the weights 31a and 31b will advantageously be made of steel to give them a certain weight, and the housing 33 of the shoe 15 will be dimensioned so that the weights can be stuck there.
  • the shoe 15 is retained by the cover 45 and the projectile 5 separates from the shoe 15 by aerodynamic effect.
  • the fact that the counterweight 31a is wedged in the housing 33 of the shoe 15 facilitates this separation.
  • the projectile control electronics 13 ignites the pyrotechnic impellers 12 to impart a rotational movement to the projectile 5 around the vertical axis YY.
  • the detection beam 10a scans the ground in a spiral-shaped imprint and as soon as the target is detected, the load 9 is pulled along the axis XX, in a manner known per se.
  • the launch tube 3 is oriented according to a determined elevation angle.
  • the operator who sets up the mine 1 on the ground uses another platform 2 comprising a hollow cylindrical body 50 inclined at the above-mentioned site angle and which has a bottom wall 51.
  • the body 50 is mounted for rotation about a vertical axis A on a horizontal plate 52 which rests on the ground by feet 53 adjustable in height.
  • the operator positions the platform 2 on the ground and adjusts the horizontality of the plate 52 by individually adjusting the height of each foot 53, the plate 52 being able to incorporate a spirit level 55 for example to facilitate adjustments.
  • the operator introduces the launching tube 3 into the body 50 and then positions the projectile 5 inside the tube 3 so that the ball 22 of the positioning system 20 is partly received in the housing 27b of the shoe 15 , the counterweight 31b of the immobilization device 30 then being located opposite the housing 33 of the shoe 15.
  • the projectile 5 is then in the same position as before (fi gure 2), that is to say that its axis of rotation is always oriented along the vertical materialized by the YY axis.
  • the mine monitoring system 1 When the mine monitoring system 1 has detected a target in the mine efficiency area, it calculates the bearing angle of the target and controls the rotation of the body 50 on the plate 52 of the platform 2 by motor means, for example a stepping motor, to orient the launching tube 3 according to the angle of bearing previously calculated. Then, the projectile is fired as before, with firing of the pyrotechnic impellers 12 to impart to it a rotational movement along the vertical axis YY, that is to say along an axis different from that of the vector speed. As soon as the detection beam 1 Oa has detected the target, the charge 9 is pulled along the axis XX, in a manner known per se.
  • motor means for example a stepping motor
  • the shoe 15 is made up of two parts 15a and 15b.
  • the first part 15a of the shoe 15 consists of a body 60 with a convex bottom wall 61 and whose face 62 opposite this bottom wall 61 is rectangular.
  • a central housing 63 is provided in the face 62 of the body 60 to receive there in part the projectile 5 which has a casing 8 of cylindrical shape in this embodiment.
  • the projectile 5 is for example retained in the housing 63 by bonding.
  • the second part 15b of the shoe consists of a cylindrical body 65 which rests at the bottom of the launching tube 3.
  • the upper face 66 of the body 65 has a central cavity 16 having a rectangular opening 16a and a bottom wall 16b of complementary shape to that of the bottom wall 61 of the body 60 of the first part 15a of the shoe to receive the latter.
  • the positioning system 20 which makes it possible to orient the projectile 5 relative to the shoe 15 is of the same type as that described above, and it is mounted at the interface between the two parts 15a and 15b of the shoe 15.
  • the platform 2 described is used either in FIG. 1 for a mode of operation at low range, or in FIG. 4 for a mode of operation at medium range.
  • the invention is in no way limited to the means described and it includes all the technical equivalents of these means without departing from the scope of the invention, in particular at the level of the positioning system 21 to maintain the axis of rotation of the projectile 5 oriented along a given axis.
