Definitions

  • the technical sector of the present invention is that of directed effect mines usable against armored vehicles, which can operate whatever its mode of laying.
  • Patent BE-A-626,902 describes an antipersonnel mine operating using a low pressure and for which the height / diameter ratio shown in the figure is less than 0.5. However, this mine does not have a formed charge and does not include a semi-rigid damping structure.
  • US-A-4,040,354 describes an anti-tank mine which can be dropped from an aircraft and whose height / diameter ratio is less than 0.5. However, this mine is not equipped with a damping structure.
  • the first type has only one charge; in the event that, during installation, the load is not facing the objective, an additional device acts to ensure its reversal. In reality, this device gives a new possibility to the mine to reposition itself correctly, which does not imply certain obtaining of the expected result.
  • the second type of mine makes it possible to considerably increase the probability of obtaining a mine laid under good conditions. To do this, the mine comprises a bead of elastomeric polyurethane to ensure the protection and the hold of the whole of the mine and to fix the external shape and a bi-directional charge formed with igniter selecting the direction of progression of the detonation towards the objective to destroy.
  • An object of the present invention is to provide a remedy to this problem by providing a mine having a very high probability of laying in good conditions and this whatever its mode of dispersion and whatever the terrain to be mined.
  • the mines must not be damaged after their contact with the ground .
  • the mines previously proposed were equipped with braking devices such as parachutes or stabilizers in order to reduce the shocks which risked damaging the electronic circuits or the load itself and which, consequently, markedly reduced the reliability of these mines.
  • Another object of the present invention is to provide a simple and low cost solution to this problem, while making it possible to eliminate the braking devices and by offering more compact, less complex and more easily accommodated leads in bodies. shells, rockets or missiles or in distributing devices for planes, helicopters or trucks.
  • the subject of the invention is a charged mine formed with directed effect in one of the two opposite directions of an axis X'X perpendicular to the median plane of the mine having a generally flattened shape, comprising in particular a substantially cylindrical housing containing the charge and at the ends of which are fixed two metallic coatings, an igniter possibly provided with an arming puller extracted by a spring, the axis X'X constituting the axis of symmetry of the coatings, the ratio height h to external diameter d of the mine being less than 0.5, characterized in that it comprises damping means surrounding the housing constituted by a layer of damping material on which are fixed flexible tongues on either side of the median plane and at a determined distance therefrom, their free ends deviating from the axis of revolution and then being substantially in the median plane of the mine, thus ensuring installation according to one or the other of the d preferential directions.
  • a characteristic of the mine according to the invention is that the flexible tongues are regularly arranged around the mine, and are fixed on either side and at a determined distance from the median plane of the mine, their free ends deviating from the axis of revolution and being substantially in the median plane of the mine.
  • the damping means are constituted on the one hand by a metal frame surrounding the housing and composed of two washers arranged in planes substantially parallel to the median plane connected to each other by spacers embedded in a damping material and on the other hand, by flexible tongues fixed on the washers on either side of the median plane and at a determined distance from this, their free ends deviating from the axis of revolution and then being substantially in the median plane of the mine.
  • an explosive charge 1 between two coatings 2a and 2b secured to a substantially cylindrical housing 3.
  • the coatings 2a and 2b are arranged at the ends of the housing along the same axis XX 'and are capable of generating formed charge jets going in two opposite directions; the two coatings are conventionally either flat or conical and made of copper.
  • These mines also have a central tube 4 in which is placed a priming system 5 movable by gravity which can be maintained in the safety position, that is to say in the central position by an appropriate device which unlocks the system to the opportune moment.
  • the mine has a generally flattened shape, for example a truncated ellipsoid.
  • the mine shown in Figure 1 consists, in addition to the load described above, of two washers 6 and 7 regularly braced by tie rods 8 which are secured by their ends to the washers, for example riveting.
  • This assembly thus forms a skeleton, for example made of metal capable of withstanding a large part of the forces due to shocks during installation.
  • This structure is embedded in a shock absorbing material 9, the shock absorbing material - skeleton couple thus formed being capable of undergoing very violent shocks while very effectively protecting the explosive charge.
  • the igniter 10 has been placed in the center of the explosive charge, where it is particularly well protected, and which also makes it possible to use it as a wave-forming screen.
  • the mine according to the invention has a cocking rod 11, making it possible to have a storage security, which acts on the priming system either directly or via the igniter 10.
  • This mine also has flexible tongues 12 regularly distributed around its periphery and fixed on the two washers 6 and 7.The free ends of these tongues are located approximately in the median plane of the mine and allow an outside diameter d of such that the height ratio h of the mine over d is at most equal to 0.5, which offers a very low probability of laying on the edge.
  • These flexible tabs can be foldable and in this case can be placed in housings 13 formed in the damping material. This possibility offers the advantage of being able to place this type of mine in shells, missiles, rockets or containers without the size of the mine being too great, most of the available space being left to the load. proper.
  • the cocking rod 11 is usually ejected by a spring, a pin 14 holding it in place until mounting in a projectile or container.
  • the flexibility of the tabs was used to facilitate the extraction of the zipper; the T-shaped outer end 15 is engaged in the recessed part 16 of the corresponding flexible tongue, so as to allow ejection through the recessed part 16.
  • the tongues can be fixed on the very layer of damping material 9 by removing the skeleton (6, 7, 8), which makes it possible to facilitate manufacture and to reduce the cost price.
  • Materials of the cellular resin or elastomer type with large elongation are remarkably suitable for producing shock-absorbing material.
  • the semi-rigid structure of the mine represented in FIG. 2 is constituted in an identical manner to that of FIG. 1, that is to say by two metal washers 6 and 7 of appropriate shape braced by tie rods 8.
  • the h / d ratio has been reduced by placing the igniter 10 at the heart of the damping material, outside the charge formed. Still relative to FIG. 1, the flexible tongues are suppressed, the external shape of the lead being that described in FIG. 2.
  • the mine shown in Figure 3 is made so that it can be housed in a cylindrical container such as the military head of a rocket or missile.
  • Its external shape is that of a circular sector of diameter D corresponding to the internal diameter of the container in which this type of mine is placed.
  • the circular sector has an angle at the top equal to 2 3 ir so as to be able to accommodate three mines side by side. It is understood that one can vary the number of mines, account given the available diameter of the container.
  • This type of mine is equipped with flexible folding tongues 12 which contribute with the very flat external shape, to allow the laying in excellent conditions.
  • the constitution of the semi-rigid structure can be that used for the construction of one of the mines described above.
