Definitions

  • the present invention relates to a projectile equipped with a shield wall including a projectile with pyrotechnic charge, located between the pyrotechnic part and the control and control part. It applies in particular for shells or rockets whose denotation is programmed a given delay after impact on the target.
  • the shell or rocket has at least two parts, a control and control part located at the front, followed by a part comprising the pyrotechnic charge.
  • the control and control part includes proximity sensors that determine the distance to the target and a control unit that activates the pyrotechnic charge depending in particular on the distance of the shell to the target. The firing of the charge is caused by an electrical signal from the command and control part of the shell.
  • Delay circuits may be located in the pyrotechnic portion in particular for delaying the initiation of firing of the load following the activation signal provided by the control portion. This delay is for example a few thousandths to a few tens of thousandths of a second.
  • An electric wire more generally a flex or a strand son, must therefore pass from the control and control part to the pyrotechnic part to allow the passage of control signals, for example to initiate the firing.
  • These two parts are separated by a wall comprising a shield partition.
  • the pyrotechnic part and in particular its firing system must not be destroyed by the spray debris caused by the impact of the shell head, in particularly its control and control part, on the target, for example a concrete wall.
  • the shield partition is placed at the level of what is called the eye of the shell.
  • the aforementioned flex or son strand to cross the wall separating the two parts must actually cross the shield partition.
  • a hole is necessary to let the wire pass.
  • the different materials constituting the target are sprayed and rush into the hole.
  • These debris then deteriorate the mechanisms and electronic modules located behind the shield partition, in the pyrotechnic part in particular.
  • Solutions are known to prevent the passage of spray materials into the hole.
  • baffles are made to slow or even stop the crossing of these materials.
  • Another solution is to make small slots just let the wires.
  • the thickness of the partition may be for example of the order of 10 to 20 millimeters. Performing baffles or thin slits in such thicknesses is complicated. This results in particular an additional cost of production of parts.
  • the conduit has at least one cylindrical portion and one conical portion, the conical portion being oriented forward.
  • the engaged part of the plug is for example of conical shape,
  • the conical portion of the duct and the conical portion of the plug have substantially the same angle.
  • the conduit comprises a first cylindrical portion and a second cylindrical portion of larger section, the cylindrical portion of larger section being oriented forward.
  • the engaged part of the cap is for example of cylindrical shape of section greater than the section of the first cylindrical portion of the conduit to close the latter when the plug comes into contact with it.
  • the conduit and the plug are for example symmetrical of revolution.
  • the zone of mechanical weakness is for example an area of the support portion of reduced thickness.
  • a part of the projectile comprises for example a pyrotechnic charge and the other part placed at the front of the projectile comprises for example a control and control system, the front of the shield-partition being oriented towards this part of command and control.
  • the main advantages of the invention are that it makes it possible to produce robust shield-wall parts, that it improves the reliability of a projectile equipped with such a shield-partition and that it is simple to implement.
  • FIG. 1a presents, by a simple diagram, the situation of a shield partition in a shell 1.
  • the shell comprises at least two parts 2, 3.
  • a first part 2, located at the front of the shell, comprises by example the command and control system of the shell.
  • the second part 3 includes its pyrotechnic charge.
  • a wall 4 separates for example the two parts.
  • the wall 4 is itself closed by the shield-wall 5 located substantially in its center, at what is generally called the eye of the shell.
  • the wires carrying the control signals pass through the shield wall 5.
  • the spray materials When the shell is impacted on a target, the spray materials must not pass through the hole of the shield-shield for the passage of the wires, in particular to protect the firing mechanisms and the electronic modules located in the pyrotechnic part 2.
  • These electronic modules are for example programmed to create a firing delay in response to an activation signal from the control part 1 and control.
  • This delay is for example defined so that the shell detonates for example after partially penetrating the target.
  • This target can be, for example, a concrete wall, a hard or loose floor or a metal structure.
  • the shield-partition 5 will be called shield.
  • Figure 1b illustrates the position of a shield in a rocket.
  • the rocket 1 also has two parts 2, 3.
  • the first part 2, located at the front of the rocket, comprises for example the control and control system of the rocket.
  • the second part 3 comprises in particular its pyrotechnic charge.
  • a wall 4 separates the two parts.
  • the wall 4 is closed by the shield 5 located substantially at its center.
  • the wires carrying the control signals pass through the shield partition 5.
  • FIG. 2 illustrates, in sectional view, an exemplary possible embodiment of a shield according to the invention.
  • the shield 5 is for example symmetrical of revolution, the section of Figure 2 passes through the axis of symmetry 20 of the shield.
  • the shield 5 has a partition 21, thick enough to withstand the pressure caused by the impact of the shell on a target.
  • the wall 21 made of metal, for example, is pierced with a duct 22 in which a plug 23 is engaged.
  • the duct 22 is located in the center of the wall 21.
  • the duct is composed of a cylindrical portion 221 and a conical portion 222.
  • the cylindrical portion 221 of the conduit is oriented towards the pyrotechnic charge, the conical portion 222 facing the control and control system, it is ie oriented towards the front of the shell.
  • the plug 23 has a conical portion 231 facing the conical portion 222 of the conduit. A gap is maintained between the conduit wall and the plug 23 so as to leave a passage 25 for an electrical wire 24, a son strand, a wire braid or a flex.
  • this space is intended to pass links 24 necessary for the transmission of signals between the front of the shield, oriented for example towards the control and control system of a shell, and the rear of the shield, oriented by example to the pyrotechnic charge of a shell.
  • the cap 23 comprises for example a plate 232 mechanically integral with this conical portion.
  • the plate 232 rests for example on the wall 21 of the shield.
  • a hollow matching the shape of the plate is for example made in the wall 21 in which is placed the plate 232, the conical portion 231 of the cap being engaged in the conduit 22.
  • the plate 232 forms for example a flat cylinder of a kind that the plug 23 as a whole forms a symmetrical component of revolution, centered on the axis of symmetry 20 of the shield 5.
  • the plate is for example forcibly engaged in the wall, or welded, for holding in the closed position or in near-closure, leaving just the passage space 25.
  • the plate comprises for example a slot 233 to let the 24. More generally an opening 233 in the tray made opposite the opening or passage space 25, provides a complete opening.
  • the conical portion 231 of the cap 23 and the plate 232 are mechanically secured, so they can in particular form a single piece. However, their mechanical connection comprises, for example, a zone of weakness 26 so that the conical portion 231 can separate from the plate 232.
  • This zone of mechanical fragility 26 is for example constituted by a part of the plate of lesser thickness. By way of example, it may be formed of a circular zone 26 of small thickness, this zone connecting the plate 232 to the conical portion 231, all nevertheless forming a single piece. In the event of pressure exerted on the plug, the conical portion can then be detached from the plate 232 by shearing.
  • the wall 21 is for example extended on each of its sides by a hollow portion 211, 212, forming for example a hollow cylinder.
  • a not shown thread may be provided for, for example, screw the shield on a support, or more particularly in the eye of the shell.
  • FIG. 2 represents a shield according to the invention before impacting on a target of the projectile which comprises it.
  • the shield closes a passage separating two parts of the projectile, for example the control and control part 2 of the pyrotechnic part 3 of a shell, while allowing a wire, a group of wires or any other type to pass through. of links 24.
  • Figure 3 shows the state of the shield after impact of the projectile, or shell, on a target, for example on a concrete wall.
  • the front of the shield and more particularly the plug 23 is subjected to a pressure 31 such that the conical portion 231 separates from its support, for example the plate 232, the separation is made at the zone 26 of mechanical fragility by shearing.
  • the conical portion 231 of the stopper is then pushed onto the flared face of the duct, its conical opening, so that the conical portion 231 encloses the space 25 through which the connection 24 passes.
  • the angle of the cone 231 of the shield is substantially the same as that of the opening cone of the led 22 so as to optimize the closure.
  • the closure of the space 25 causes the cut or deterioration of the link 24, however it does not matter for the rest of the operational phase. Indeed, the electrical modules located at the rear of the shield 5 remain intact because protected especially of the spray materials due to the impact on the target. In particular delays programmed in the electronic modules are still active. A firing delay can then be created from an activation signal transmitted by the link 24 passing through the shield, in accordance with the programmed instructions.
  • FIG. 4 shows another possible embodiment of a shield according to the invention.
  • the plug 23 and the duct 22 have different shapes from those of FIGS. 2 and 3.
  • the duct 22 always comprises two parts, a first cylindrical portion 221, as in the case of FIGS. facing the back of the shield.

  • the support 232 which may take the form of a cylindrical plate is mechanically connected to another portion 231 'of the plug 23 via a zone of mechanical weakness, as in the previous embodiment.
  • This other part 231 'of the plug is that which is engaged in the conduit 22, it has for example a shape cylindrical adapted to the cylindrical wall of the duct.
  • This portion 231 'of the plug has a section at least greater than the section of the first cylindrical portion 221 of the conduit.
  • the support 232 of the cap is supported on the wall 21 of the shield so that a space 25 is reserved between the cap and the bottom 41 of the cylinder of the conduit.
