Definitions

  • the present invention relates to a dispersible anti-tank mine.
  • Mines of this type are distinguished in particular from buried mines, which can be planted by mechanized laying using suitable machinery; this allows in particular to place the mines very precisely (depth, orientation, ).
  • a first type of dispersible mine has been proposed, of flattened shape, that is to say having a diameter greater than the height: such a mine therefore has two large faces, and a rim narrow device; once on the ground, it rests on one or other of these faces.
  • a reversible arming system is then provided (for example with a tilting member) so that the face turned upwards is always the sensitive face of the mine.
  • Such a mine solves the difficulty of positioning, but does not lend itself to a wide variety of payloads, precisely because of its reversibility. This structure is moreover generally reserved for dispersible mines of small caliber.
  • the correct positioning is ensured by one or more latches which are deployed after impact to straighten the lead to its correct position, the sensitive side facing up.
  • latches which are deployed after impact to straighten the lead to its correct position, the sensitive side facing up.
  • the pivoting torque being at least equal to the torque necessary to cause the mine body to turn over, in the event that it rests, before opening, with its bearing face facing upwards.
  • the mine body which is advantageously of flattened shape, but without necessarily being of the reversible type, comprises a sensitive face (which will be designated hereinafter “exposed face”, as opposed to the "bearing face” by which the mine rests in contact with the ground) which will always be turned upwards: indeed, after impact and immobilization, or else the body of mine is placed from the first in good position, that is to say face exposed upwards, and the cover after opening then only uncovers this face; or else the body of mine comes to a halt upside down, that is to say face downwards and in contact with the ground, and then the opening of the cover gives it sufficient momentum to cause it to turn over at the place.
  • the cover comprises a crown extending upwards, in the closed position, the side wall of the mine body, so as to center the center of gravity of the assembly formed by the mine body and its closed cover downwards. to give this assembly, when it rests on the ground, a privileged position of stable equilibrium in which the cover is turned upwards.
  • the bearing face of the lead body is preferably a convex surface of revolution.
  • the cover comprises a continuous surface completely covering, in the closed position, the exposed face of the lead body, so as to constitute a protective shield for this exposed face.
  • the cover thus plays, in addition to the two aforementioned functions of decentering the center of gravity (before opening) and widening the bearing surface on the ground (after opening), a third function of protection of the exposed face of the mine body before its opening, i.e. during storage, during dispersion and after impact until the moment of immobilization.
  • the dimensions and the height of the crown define for the latter a shape complementary to that of the bearing face of the mine body, so as to allow a stacking of a plurality of identical mines, the crown of a mine housing, at least partially, the mine body of the adjacent mine.
  • This characteristic thus achieves a fourth function of stacking means, the female shape of the cover being homologous to the male shape of the lead body.
  • This possibility of stacking is all the more advantageous since dispersible mines are, by definition, intended to be used in large numbers; it is therefore desirable to rationalize its storage.
  • the mine comprises means for detecting the impact of the mine on the ground, capable of controlling the operation of the opening means; it also includes delay means, triggered by the impact detector means, to delay the operation of the opening means after the mine has impacted the ground.
  • the mine is advantageously a mine with a formed charge, with a projection of a plate for example ⁇ the exposed face of the mine body comprising a concave metal plate forming a projectile and the inner face of which is in direct contact with the explosive charge.
  • This type of mine classic in itself, allows to obtain maximum effects with a reduced amount of explosive: the detonation propagating by radiating from the point of initiation, the metal plate will begin to deform in the center , at the same time that it will be set in speed, thus realizing a projectile with peak effect.
  • Figure 1 shows the lead body 100 capped by its cover 200, before opening.
  • the lead body 100 comprises an envelope, for example of synthetic material, closed by a metal plate 110 constituting the exposed face of the mine, that is to say that this face is always turned upwards when the mine is in the active position.
  • This plate 110 has a generally concave shape, and its inner face is in direct contact with the explosive charge 130, according to a conventional structure for a plate projection mine.
  • the lower face 120 of the mine body which is a bearing face resting on the ground when the mine is in the active position, has a generally convex shape of revolution, with an evolving external profile between the center A of the face and the rim peripheral.
  • the explosive 130 enclosed in the mine body is a shaped charge explosive; an ignition system 140 is also provided, comprising, in addition to the pyrotechnic means for initiating the explosive, means (for example electronic) for detection, in particular for detection by influence when an armored vehicle passes.
  • the ignition device 140 is preferably programmable and activatable in energy just before the disnersion of the mines.
  • This ignition device 140 also includes means for detecting the impact of the mine on the ground, as well as delay means, triggered by these impact detector means, for delaying the arming of the pyrotechnic chain of the mine after impact. on the ground for a duration corresponding to the maximum foreseeable duration before complete immobilization (it will also be seen later that these retarding means are capable of delaying the opening of the mine cover).
  • the cover 200 is connected to the lead body 100 by an arm 230 articulated between a peripheral point 150 of the lead body and a point 250 of the cover.
  • This articulated arm for example formed by two elements 231, 232, is deployable so that, as will be seen later, in the open position, the assembly formed by the arm and the cover maintains the exposed face of the lead body in a general horizontal orientation.
  • the cover In the closed position, the cover is locked on the lead body, for example by fitting a hollow part 240 into a projecting part 111 of the exposed face 110; an explosive bolt 112 is then screwed into this projecting part to hold the cover 200 in place.
  • a charge 113 After immobilization of the mine on the ground, and for example on command of the ignition and timing means station 140, a charge 113 will be ignited by a detonator 114, thus causing the expulsion of the bolt 112.
  • FIG. 2 represents two positions of the mine immobilized on the ground, before opening: most generally, taking into account the convex shape of the bearing surface 120 and the shift of the center of gravity explained above, the mine rests on the ground in the position shown on the right of Figure 2, that is to say with its bearing face 120 actually in contact with the ground.
  • Opening means which can be mechanical means such as springs, pyrotechnic means, etc. exert on the cover a pivoting torque to move the mine from the closed position of FIG. 2 to an open position (FIG. 3) in which, after a pivoting of about 1/2 turn, the cover 200 rests, turned upside down, next to the lead body 100.
  • the opening of the cover only reveals the exposed face 110 and increases the bearing surface on the ground, thanks to the crown 210 which is then in support on the ground.
  • the dimensions of the articulated arm 230, as well as the amplitude of movement which is permitted thereto, are chosen so that the exposed face 110 of the lead body is maintained in a generally horizontal orientation, so that this face, which is the sensitive side, or oriented in the most efficient way.
  • the opening means will exert on the mine body 100 a pivoting torque at least equal to the torque necessary to cause a reversal of this mine body: it is then the cover 200 which remains in abutment on the ground, and the mine body 100 which comes to rest, in a correct orientation, next to the cover.
