Definitions
- the present invention relates to 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 shield partition is placed at the level of what is called the eye of the shell. Or 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. In the absence of precaution, under the pressure of the shock 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. In particular, baffles are made to slow or even stop the crossing of these materials. Another solution is to make small slots just let the wires. However, such solutions are complex to implement. Indeed, 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 subject of the invention is a shield partition comprising at least: a pierced wall of a duct; a plug composed of a support part and a part engaged in the conduit leaving a space between itself and the wall of the conduit, the two parts being connected by an area of mechanical weakness; the support part bearing on the wall, at the front, so that the engaged part separates from the support part under the effect of an external pressure to come into contact with the inner wall of the duct and close the space .
- 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.
- the invention also relates to a projectile comprising at least two parts separated by such a shield-partition, a signal transmission link passing through the space left between the wall of the conduit and the plug.
- a part comprises a pyrotechnic charge
- the other part placed at the front of the projectile comprises, for example, a control and control system, the front of the shield wall being oriented towards this control and control part.
- 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 the situation of a shield partition in a projectile, for example a shell
- - Figure 1b the situation of a shield partition in another type of projectile, for example a rocket
- FIG. 2 a first possible embodiment of a shield partition according to the invention
- - Figure 3 the state of this shield partition after impact
- FIG. 4 another possible embodiment of a shield partition according to the invention.
- - Figure 5 another embodiment of a plug used in a shield wall according to the invention;
- Figure 6 the position of the previous cap in a shield wall according to the invention.
- 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 partition 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 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 also has two parts 2, 3.
- the first part 2, located at the front of the rocket, comprises for example the rocket control and control system.
- 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.
- a second portion 222 'in which the cap 23 is engaged has a wall 41 disposed facing the wall of the cap so as to reserve a space between the wall of the duct and the wall of the cap.
- This space 25 is provided for the passage of a link, this connection may be an electrical wire or a group of son in the form of strand, braid or flex.
- the portion 222 'of the conduit which receives the plug 23 forms a cylinder.
- the duct 22 thus comprises two cylindrical parts of different sections.
- the plug 23 is engaged in the cylinder of larger section.
- the plug 23 is for example always composed of a support 232 bearing on the wall 21 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.
- the cylindrical portion 231 'of the cap disengages from the support 232 and abuts on the bottom 41 of the cylinder of the conduit 22.
- the front and the rear of the shield are then well closed to each other.
- the support 232 of the cap 23 also comprises for example a slot 233 for passing the connection.
- the cylinders 231 ', 232 forming the cap are for example symmetrical of revolution. It is possible to provide embodiments where the two cylinders are not symmetrical of revolution.
- the cylinder 222 'of the conduit in which the plug is engaged will accordingly have a suitable shape, and the section of the plug will be large enough to close the first cylinder 221.
- FIG. 5 shows another embodiment of the plug 23 used in a shield according to the invention.
- the portion 231 of the plug engaged in the conduit 22 has a conical shape. It is possible to provide another embodiment where this part would have another shape, for example of the flat cylinder type as illustrated in FIG. 4.
- the conical portion 231 is always connected to the support 232 by an area of mechanical weakness 26 '. Nevertheless, in this embodiment, this zone 26 'is a rod of small section.
- the cone 231, the rod 26 'and the support 232 form for example a single mechanical part.
- the support may, for example, be supported on the partition by pins 51.
- Figure 6 shows in a sectional view and in perspective the position of a plug, as shown in Figure 5, in a shield according to the invention.
- the wall 21 is extended, for example, to form a well 61 which opens out onto the duct 22.
- the support 232 of the plug 23 is then placed at the bottom of the well, opposite the duct 22.
- the rod 26 crosses the well.
- the support 232 of the cap has a shape that does not close the well 61, so as to allow the one or more connections 24 and secondly to allow the pressure causing the rupture of the rod 26 '.
- the conduit 22 of the shield has an inner surface substantially parallel to a surface of the plug 23 engaged in the conduit, with a space 25 reserved between these two surfaces . Under the effect of an external pressure both surfaces come into contact to close the shield.
- the invention is economical and simple to implement.
- the component parts of a shield according to the invention can be symmetrical of revolution without particular bore. There are at most two bores to predict.
- a bore for the conduit 22 is simple to make. It is the same to make the slot 22 of the plug support for passing the links. This embodiment also makes it possible to obtain robust parts.
- a projectile at most equipped with such a shield is therefore more reliable and also less expensive to achieve.
- the shield 3 separates the pyrotechnic portion of the projectile or the shell of the control portion and 2.
- a control link 24, for example electric, transmits signals between the two parties.
