Definitions

  • the field of the present invention is that of priming devices for submunitions of cargo shells, in particular for anti-personnel and anti-vehicle grenades dropped in large numbers above a target, according to the so-called technique. of "saturation".
  • a cargo shell is a shell whose usual explosive charge has been replaced by a large number of submunitions or sub-projectiles.
  • the submunitions are grenades constituted by a cylindrical fragmentation body having an anti-personnel effect by projection of splinters, and closed at one end by a coating of hollow charge allowing aggression by the roof light or weakly armored vehicles.
  • the other end of the body supports the initiating device responsible for initiating the explosive charge contained in the body.
  • these grenades are stacked on several columns inside the cargo shell, the priming device turned towards the base occupies the space left free by the coating of the hollow charge of the neighboring grenade, or is housed in a shape provided for this purpose in the base of the cargo shell.
  • the grenades are then ejected and dispersed on the trajectory of the shell during a phase known as stripping, with a speed of rotation around their axis which is close to the speed that the shell had at the time of stripping.
  • the main technical function of the initiating device is to ignite as safely as possible the initiation of the main charge of the submunition at the time of its impact, after a normal fire on the one hand, and prohibit this firing in the event of simple impact or manipulation on the other hand.
  • It can also include a device capable of neutralizing, that is to say preventing any ignition following a manipulation when after a normal launching the ignition has not occurred.
  • the firing safety can be supplemented by a self-destruction system ignited independently of the main firing and which causes the self-destruction of the submunition by firing the main charge after a certain delay .
  • this priming device comprises a primer placed in a sliding drawer, which a striker strikes at the moment of impact, moved by its own inertia.
  • the safety of firing is supplemented by self-destruction, the firing of which is caused by the rotation of the sub-projectile.
  • the prohibition of operation during simple manipulations or shocks stems from the fact that in the storage position the drawer is in a position such that the primer which it carries is not in alignment with the rest of the pyrotechnic chain and that the drawer is held in this position by the striker as long as the latter is not in the armed position.
  • This same spring neutralizes the priming system by bringing the drawer into a misaligned and locked position in the event of insufficient rotation speed or no impact after impact.
  • the self-destruction system comprises a primer secured to the drawer and coming under the effect of centrifugal force to strike a striker secured to the body of the primer device.
  • This primer in turn initiates a retarding composition placed in a groove formed on a face of a disc interposed between the initiation system and the main charge, and having in the axis of the striker a priming relay that can be initiated, either by the main primer or by the retarding composition.
  • a vent practiced laterally in the housing of the concurrent primer and coming in relation to the retarding composition, allows its initiation.
  • the method of loading the retarding composition is difficult to implement. It will be difficult to obtain a homogeneous composition, ensuring good regularity of combustion, and thereafter delays which are reproducible from one priming device to another.
  • this priming device is composed of a large number of parts, which makes it an expensive assembly.
  • the body is a complex foundry part generally made from a zinc alloy and it ensures both the housing of the different parts as well as the fixing and the maintenance of the priming device on the body of the sub- ammunition.
  • Patent DE3144996 describes a security and arming device which is intended to equip a projectile. This device comprises a latch disposed in a longitudinal direction of the device and which disappears under the action of the projectile starting acceleration.
  • the amplitude of the erasure of this lock as well as the period during which it remains erased depends on the conditions of firing of the projectile. Thus, to be operational, the lock must be able to move away from the rotor only for significant accelerations. When the firing conditions are not correct, the lock returns to immobilize the rotor and prevents its passage into the armed position.
  • the invention therefore relates to a device of the type described in US Pat. No. 4,612,858, but by design and construction having increased safety, this with a reduced number of mechanical parts, while respecting the constraints associated with this. kind of devices, which were explained above. Finally, it aims to produce a priming device comprising more reliable and possibly removable self-destruction means, and reliable neutralization means.
  • US 4,612,858 describes the characteristics of the preamble of claim 1.
  • This construction has the advantage of locking the drawer in a known position and preventing the priming of the main chain on the one hand and of a possible delay chain on the other hand.
  • the neutralization device requires a movement of the drawer bringing the latter into a neutralization position, movement which cannot take place if the drawer is blocked.
  • the device proposed by the invention by interposing a mechanical obstacle on the path of the drawer ensures such neutralization whatever the state of the springs actuating the drawer.
  • the device according to the invention comprises a delay self-destruction means constituted by a primer, a delay cord, a priming relay and a striker mounted on the drawer.
  • Such a variant makes it possible to obtain an easy design delay since the cord is produced independently of the initiating device.
  • the priming system for submunitions of cargo shells 1 is intended as explained above to be mounted on submunitions 2, housed in large numbers in this shell.
  • Each submunition is designed so that the priming device for one is housed in the space left free inside the coating of the hollow charge of the next submunition.
  • the detail of this housing is shown in Figure 1 in which we see the coating 3 of hollow charge of a submunition comprising an explosive charge 4, coating inside which is housed the initiating device 5 of the neighboring submunition.
  • This figure is intended to illustrate the conventional arrangement of submunitions 2 in the shell, the priming system being oriented towards the base 6 of the shell.
  • the initiating device according to the invention shown in the safety position, consists of a body 7, disposed inside a metal mask 44 made of stamped sheet metal and the internal profile follows the external profile of the body 7.
  • the mask 44 thus covers the body 7 which supports all of the priming means, the body being kept in contact with the mask by a closing disc 13 itself bearing on the explosive charge 4.
  • the mask carrying the initiating device is joined to the explosive charge by means of an annular crimping 45 on the metal casing 47 of the charge (see FIG. 7), but any other mode of connection would be possible.
  • the mask constitutes a reinforcement of the body and allows it to be dimensioned allowing the use of plastics. In fact, the forces transmitted during movements of the submunitions by the parts constituting the initiating device according to the invention will be absorbed by the mask, the rigidity of which is sufficient. This avoids having to use a complex profile foundry to produce the initiation device.
  • a transverse groove 48 Inside the body 7 is arranged a transverse groove 48 inside which is slidably mounted a drawer 8, carrying a primer 9.
  • the drawer is pushed into its groove by a compression spring 10 bearing on one side on one end 11 of a recess arranged in the drawer and on the other on a lug 12 of the closing disc 13 of the body 7.
  • the body also has a longitudinal bore 49 inside which a striker 16 is slidably mounted.
  • the latter comprises an axial bore 50 inside which is disposed a sliding rod 32, the latter carries a shoulder 35 intended to abut on a washer 36 made integral with the striker 16 by crimping.
  • a textile tape 31 is linked to the telescopic rod 32 by means of a washer 33 held by a crimping 34.
  • the striker also carries a flange 15 which is received when the device is in the safety position in a groove 14 of the drawer 8, which thus immobilizes the striker in translation.
  • Figures 3 and 4 show a first blocking means constituted by a counterweight 18, bearing in a housing 29 of the body 7 and on an imprint 46 made on the drawer so as to block the latter (fig 3).
  • the counterweight is held in position by a compression spring 19, adjusted on one side in a blind bore of the counterweight 18 and guided on the other side over a short length by a pin 20 secured to the body 7.
  • this lock is designed so as to function only during sufficient accelerations and strokes of the counterweight (acceleration of the order of 900 g), this in order to protect against accidental unlocking consecutive to rough handling or falls during storage or handling periods.
  • the counterweight 18, the spring 19 and the pin 20 are aligned along an axis YY ′ parallel to the longitudinal axis XX ′ of the submunition and to the acceleration vector of the projectile at the start of the shot.
  • a recess 30 is arranged in the body 7 all around the axis YY '(see Figure 5), the function of this recess will be explained below.
  • the drawer is then still immobilized in a safety position but the flange 15 is released from the groove 14, allowing translation of the striker.
  • the drawer 8 carries a pin 38 ( Figure 3) pushed by a spring 39, intended to engage in a hole 40 of the body 7 so as to lock the drawer in the armed position.
  • FIGS. 3, 5 and 6 there is a representation of a self-destruction device comprising a striker 24 integral with the drawer 8, and a retarder assembly consisting of a primer 21 and a priming relay 22 , set on a flexible delay cord 23.
  • the priming device also comprises a neutralization means comprising a centrifugal trigger 25 held in the safety position shown in FIG. 3 by a torsion spring 26 and accommodating its free end 51 between the striker 24 and the primer 21 of the delay system, thus creating an obstacle preventing any passage of the drawer into its armed position.
  • the trigger carries at its free end 51 opposite the striker 24 a housing 43 whose function will be explained below.
  • the retarder assembly is fixed to the outside of the body 7 by support pieces 27 and 28 made integral with the body 8 by means of a snap not shown (see Figures 3, 5 and 6).
  • the operation of the device is as follows: At the start of the blow, the shell undergoes an acceleration and a rotation. By inertia, the counterweight 18 then compresses the spring 19 along the axis YY ′ and is found in the recess 30. The rotation of the projectile generating a centrifugal force, the counterweight 18 is offset and wedged across the recess 30.
  • the counterweight 18 cannot, as a result of its offset, return to its place even after the acceleration phase has ended.
  • the submunitions are ejected out of the shell with a speed of rotation around their axis substantially equal to that of the shell at the time of the unloading.
  • the centrifugal force causes the separation of the trigger 25, as well as the translation of the drawer 8 pushed by the spring 10, the flange 15 is then released from the groove 14, and the striker free to translate.
  • the ribbon 31 (fig 7) is deployed and pulls the telescopic rod 32 which abuts on the washer 36, then extracts the striker 16 from its housing 17.
  • the drawer then passes into the armed position and at the same time, the striker 24 initiates the self-destruction device, the drawer is locked by the pin 38 engaged in the hole 40.
  • the positioning of the primer 9 is ensured by the lug 12 on which the end 37 of the spring housing 10 comes into abutment.
  • the submunition hits the target on the side of the hollow charge and at the same time undergoes a very strong deceleration.
  • the striker 16 strikes and initiates the primer 9 and consequently the hollow charge 4.
  • the submunition sees its fall braked gradually, for example by branches holding the ribbon 31, the initiation of the charge is nevertheless ensured by the self-destruction device.
  • the primer 21 has ignited the delay cord 23 which will initiate the primer 9 by means of the priming relay 22 and through two recesses 41 and 42 made respectively in the drawer 8 and the body 7 (FIG 7).
  • the self-destruction sequence begins when the ignition device passes into the armed position and continues thereafter, whatever the environmental conditions encountered by the submunition during its fall, which constitutes a guarantee of reliability.
  • this self-destruction can only initiate the main charge if the drawer 8 is in the armed position, the recess 41 then being opposite the recess 42.
  • the shape of the housing 43 is complementary to that of the striker 24 so as to produce, in the event of displacement of the drawer bringing this striker inside the housing 43, an irreversible jamming of these elements, which increases the safety of the device during subsequent manipulations.
  • Figures 8 to 12 show a second embodiment of the initiating device according to the invention, in which elements similar to those described above have the same reference numerals.
  • the body 7 is a foundry of a zinc alloy (Zamac) produced for example by the lost wax process.
  • Zamac zinc alloy
  • a drawer 8 disposed in a transverse groove 48 of the body 7, and held by a closing disc 13 made integral with the body 7 by a not shown fixing means (screws or rivets).
  • the drawer is pushed by the spring 10 which bears on one side on a lug 12 of the disc 13.
  • the spring 10 is disposed on a rod 52 which allows it to be compressed in order to place it in its housing, a split washer 53 is introduced between the spring 10 and the head of the rod 52 by an opening 54 of the disc 13. This washer thus secures the rod 52 and the drawer 8.
  • the striker 16 is slidably mounted in the longitudinal bore 49, in this variant it does not have a telescopic rod, but carries the textile tape 31 fixed by means of a washer 33 held by a crimping 34.
  • the flange 15 of the striker 16 is housed in the groove 14 of the drawer 8 which thus immobilizes the striker in translation.
  • a steel strapping 55 receives the priming system and is made integral with it by transverse connecting means not shown (screws or rivets), it makes it possible to make the priming system integral with the body of the load (not shown here) at by means of an annular crimp similar to the crimp 45 shown in FIGS. 6 and 7.
  • the rotating brake fins 56 are folded over the hoop 55 and welded to it by one of their ends.
  • the locking of the drawer in the armed position is ensured by a plunger 57 slidably mounted in a housing 58 of the body 7 and pushed by a spring.
  • This plunger is held by a cover 59 made of plastic material which is supported on a flat face of the body 7 and made integral with the latter by rivets (not shown).
  • the cover 59 also carries the pin 20 which guides the spring 19 of the counterweight 18 (see FIG. 9), this counterweight constitutes the first means of blocking the drawer 8 as has already been described for the first embodiment.
  • Figures 10, 11 and 12 show the self-destruction device which comprises as before a striker 24 secured to the drawer 8, and a retarder assembly consisting of a primer 21, a priming relay 22 and a flexible delay cord 23 (see Figures 11 and 12).
  • the primer is an percussion-sensitive igniter which is not attached to the delay cord but which is attached to the body 7 opposite the striker 24.
  • a chimney 60 arranged in the body 7, connects the igniter to the delay cord 23.
  • Such an arrangement makes it possible to use a cord of reduced length and having only one curvature, which facilitates its positioning on the body 7 by simple adjustment inside the parallel transverse bores 61 and 62, and guarantees reliability. of transmission.
  • the flames produced by the initiation of the igniter will be guided by the chimney 60 and will initiate the delay cord 23 by means of an ignition composition 63 sensitive to heat or to the flame (for example a known mixture of Zirconium and Barium chromate).
