Definitions

  • the present invention relates to a projectile of the type housing a pyrotechnic charge and means for delayed initiation of this pyrotechnic charge.
  • the presence of the initiation means at one end of the projectile constitutes an obstacle to a homogeneous distribution of the effects of the pyrotechnic charge, when such a homogeneous distribution is desired.
  • the explosion or sudden ignition of the pyrotechnic charge by the delayed initiation means violently projects the latter, with the part of the projectile which contains them, on the side where these delayed initiation means are located; this drawback is particularly noticeable in the case of decoy launching projectiles or lighting projectiles; in fact, the delayed initiation means are then generally located at the rear of the projectile, with reference to a firing direction thereof, and are therefore projected towards the personnel and the firing device while, generally, the delay in initiating the pyrotechnic charge with respect to the firing is established so that the distance at which the projectile is located by the personnel and the firing device when the pyrotechnic charge is initiated is small, that is to say often less than the distance that the part of the projectile containing the delayed initiation means can cross in return under the effect of the blast resulting from the explosion or sudden ignition of the pyrotechnic charge; this results in a non-negligible danger for the personnel and the firing device.
  • the present invention provides a projectile of the type housing a pyrotechnic charge and means for delayed initiation of said pyrotechnic charge, characterized in that the movens of delayed initiation are grouped in a longitudinally central section of the projectile, with reference to a longitudinal firing direction thereof, in that the pyrotechnic charge comprises two identical payloads offset longitudinally relative to said central section, respectively on the one hand and other of the latter and symmetrically of one another with respect to it, and in that the delayed initiation means are suitable for simultaneously initiating the two payloads.
  • the projectile comprises two longitudinally extreme sections each of which delimits a respective cavity for receiving a respective payload, in particular by a transverse wall mechanically weakened and defining one end of the projectile; thus, the sudden explosion or conflagration of the two payloads results in priority in a tearing of the extreme transverse walls, which longitudinally channels the flows resulting from this explosion or this conflagration and translates them into symmetrical, antagonistic longitudinal forces, applied to the central section.
  • the delayed initiation means comprise inertial initiation means, that is to say means causing initiation by inertia during firing, but other initiation means could also be used, such as by example of watchmaking resources.
  • the simultaneity of initiation of the two payloads a condition for the simultaneous application of symmetrical forces to the central section of the projectile upon explosion or sudden flashover of the two payloads, is obtained in a particularly simple manner if the priming means are single and connected to the two payloads by a pyrotechnic link chain having at least partially a T-shape defined by a first branch arranged in a transverse direction and functionally connected to the priming means, and by a second branch perpendicular to the first branch ; then, advantageously, the delay in initiating the payloads relative to the firing of the projectile is ensured by means forming a pyrotechnic delay inserted in the pyrotechnic link chain, between the means initiation and the aforementioned second branch, which in turn houses detonator means for the two payloads.
  • a mechanical safety common to the two payloads is established, that is to say simultaneously prohibiting the initiation of the two payloads or simultaneously authorizing such initiation, by providing that the section longitudinally central of the projectile also houses means for shifting the second branch with respect to a longitudinal alignment of the two payloads at least until the firing of the projectile so as to functionally interrupt the pyrotechnic link chain, and for detecting the firing of the projectile and longitudinally align the second branch with the two payloads when firing the projectile, so as to then establish a functional continuity of the pyrotechnic link chain; advantageously, means are also provided inside the central section of the projectile to delay the alignment of the second branch with the two payloads with respect to the firing of the projectile, naturally within limits such that, under normal conditions of operation, the functional continuity of the pyrotechnic link chain is established before the delayed initiation means of the pyrotechnic charge cause such an initiation.
  • the cartridge implementing the invention has been illustrated in an application in which the pyrotechnic charge is an illuminating charge, and in which the cartridge is intended to be hung under an aircraft in order to eject the projectile vertically downwards in order to illuminate the ground or to dazzle a threat on the ground or in the air, after passing by this projectile, out of the socket, of a sufficient distance to avoid damage to the aircraft by splinters during the ignition of the pyrotechnic charge; however, the characteristic provisions of the invention could be applied to other types of cartridge or projectile without departing from the scope of the present invention; in particular, the illustrated cartridge could be used in other orientations, and the references to relative orientations or levels appearing in the following description should only be interpreted as language conveniences.
  • a has designated by it 1 a longitudinal reference axis, vertical in the example illustrated, by 2 the longitudinal casing of the cartridge according to the invention, and by 3 the projectile housed with longitudinal sliding in the casing 2.
  • the side face 21 of the groove 19 is hollowed out, in the direction of a radial approximation with respect to the axis 1, of a continuous annular groove 22, itself of revolution around axis 1; in the direction of a radial approximation with respect to the axis 1, the face 18 of the wall 14 of the socket bottom is connected to a blind cavity 23 of the wall 14 of the socket bottom; this cavity 23 has a general shape of revolution around the axis 1 and is subdivided by a transverse wall 24 provided with longitudinal perforations 27 and situated at an intermediate level between those of the faces 17 and 18 of the wall 14 of the socket bottom , in a bottom zone 25, relatively closer to the face 16 and forming a bucket for receiving a pyrotechnic ejection composition 26, and in an outlet zone 28 in the face 18, which zone 28 constitutes, with a transverse face of the projectile 3 as will appear below, an expansion chamber for the gases released by the pyrotechnic ejection composition 26 and migrating
  • the projectile 3 will now be described in more detail.
  • this projectile 3 comprises an assembly of parts forming a whole integral, rigid, waterproof, or body 32.
  • this body 32 is delimited in the direction of a radial distance with respect to the axis 1 by a longitudinal external peripheral face 33, cylindrical of revolution around the axis 1, with a diameter as close as possible to that of the extreme sections 8 and 9 of the inner peripheral face 6 of the sleeve 2 and a length, measured parallel to the axis 1, substantially equal to the distance separating the bottom face of the groove 19 and the transverse face parallel to this axis 13 of the end of the sleeve 2, so that the face 33 of the body 32 of the projectile 3 is in contact with the end sections 8 and 9 of the inner peripheral face 6 of the tubular wall 4 of the sleeve 2, and this contact establishes a guide for the projectile 3 in longitudinal sliding relative to the sleeve 2; opposite respectively section 8 and section 9 of the face 6 in radial directions with reference to the axis 1, the outer peripheral face 33 of the body 32 is hollowed out of two annular grooves 234, 235, of revolution around the axis 1, each

  • the face 35 placed directly opposite the face 20 and in contact with the latter, connects the outer peripheral face 33, in the direction of a radial approximation with respect to the axis 1, to a flank face 36 cylindrical of revolution around the axis 1 towards which it is turned, with a diameter sufficiently close to that of the flank face 21 of the groove 19 so that contact is made between the faces 21 and 36 relative longitudinal sliding;
  • the flank face 36 for its part connects the end face 35, in the direction of approximation with respect to the face 34, to an end face 37 of the body 32, which face 37
  • the body 32 is longitudinally subdivided into three sections, on the basis of two longitudinally extreme sections 40 and 41, closer respectively to the face 37 and the face 34, and a longitudinally central section 42.
  • the two end sections 40 and 41 are hollow and delimit, respectively on either side of the central section 32, two sealed cavities 43, 44 which are strictly symmetrical to one another with respect to a plane 45 'perpencidular to the axis 1 and located midway between faces 34 and 37 (this plane coincides with one of the half-sectional planes identified in III - III in Figure 1); each of the cavities 43 and 44 also has a form of revolution around the axis 1.
  • the two end sections 40, 41 delimit the cavities 43, 44, along the transverse end faces 37, 34 of the body 32, by respective transverse walls 262, 263 identical and mechanically weakened by identically, with respect to the walls delimiting these cavities moreover, that is to say along the cylindrical outer peripheral face 33 of the body and along the central section 42; for this purpose, in the example illustrated, each of the walls 262, 263 has a decreasing thickness in the direction of approximation with respect to the axis 1, until reaching at its intersection with the axis 1 a minimum thickness, measured longitudinally with reference to the respectively corresponding transverse end face 37, 34; this thickness is reduced, in particular in the immediate vicinity of axis 1, to a value less than the thickness of the walls further delimiting the cavities by arrangement, in each of the transverse end faces 37, 34, of several notches identical rectilinear, respectively 260 and 261, preferably at least three in number and for example six or eight in number, oriented radially with respect to the axis on which they
  • the two cavities 43 and 44 thus defined contain useful pyrotechnic charges, respectively 45 and 46, of the same volume, of the same mass, of the same composition, which together constitute the illuminating pyrotechnic charge of the projectile 3, thus symmetrically distributed on both sides. other of the central section 42 so that, during the ignition of this load, it applies antagonistic forces to the central section 42 which make it possible to avoid the ejection of splinters from this central section 42 towards the launching aircraft, or any other launching device as well as to the launching personnel.
  • Initiation means 47 provided for this purpose are housed in the central section 42, which has, for receiving them, an interior cavity 48 sealed with respect to the two cavities 43 and 44.
  • the central section 42 of the projectile 3 and the means 47 for initiating the payloads 45 and 46 are more particularly visible in FIGS. 2 and 3, to which reference will preferably be made for the remainder of the description.
  • the cavity 48 of the central section 42 of the projectile 3 is itself subdivided in leaktight fashion into two chambers 49 and 50 mutually juxtaposed along an axis 51 intersecting from axis 1 and located in the plane 45 ', that is to say perpendicular to axis 1; for this purpose is provided inside the cavity 48 a sealed partition 52 perpendicular to the axis 51 and offset along this axis relative to the axis 1 so that the chamber 50, closed in a sealed manner, is intersecting of this axis and that the chamber 49, sealed vis-à-vis the chamber 50 but not vis-à-vis the outside of the projectile 3, is in turn entirely located on the same side of the axis 1 following direction 51; the watertight partition 52 is fixed relative to the rest of the body 32 of the projectile 3.
  • the chamber 49 opens into the outer peripheral face 33 of the body 32 of the projectile 3 by a lumen 53 having an oblong shape parallel to the axis 1, with an advantageously rectangular section perpendicular to the axis 51; inside the cavity 48, the chamber 49 is delimited around the lumen 53 by a face 54 facing the axis 1 and having the shape of a part of cylinder of revolution around this axis 1, which face 54 defines a shoulder on average perpendicular to the axis 51, around the lumen 53; the chamber 49 is moreover delimited by a cylindrical face 55 of revolution about the axis 51, which face 55 connects the face 54, in the direction of approximation with respect to the axis 1 parallel to the axis 51, to an annular face 56, of revolution about the axis 51 to which it is perpendicular, that the partition 52 has in the direction of a distance from axis 1 along axis 51; this face 56 itself connects the face 55, in the direction of a

  • Such a rotation leading to the alignment of the axis 103 with the axis 1 is prevented, as long as a predetermined time has not elapsed after the projectile 3 has left the casing 2, by a clock timer 136 with which the detonator wheel 96 cooperates via a bevel gear 137 that the rod 114 carries integrally, by its section 117, between the partition 124 and the face 126 of the chamber 50; this pinion 137 meshes with another bevel pinion 138 which in turn is mounted for rotation about an axis 139 parallel to the axis 1, relative to the body 32 of the projectile 3, and which itself carries a straight pinion 140 in engagement, by means of a reduction gear train designated by the general reference 141, with an escapement wheel 142 mounted for rotation relative to the body 32 of the projectile 3, in the chamber 50, around an axis 143 parallel to axis 1; this wheel 142 cooperates with an anchor 143 also mounted for rotation relative to the body 32, inside the chamber 50, about an axi
  • the anchor 143 is immobilized against a rotation about the axis 144 relative to the body 32 of the projectile 3, by a stud 145 then immobilized relative to the body 32 of the projectile 3, which prevents any rotation of the escape wheel 142 and, by the same, of the detonator-carrying wheel 96.
  • the stud 145 is carried integrally by a finger 146 essentially housed in a blind hole 147 arranged in the body 32 of the projectile 3 in a direction 148 approximately radial with respect to the axis 101, which blind hole 147 opens into the outer peripheral face 33 of the body 32 of the projectile;
  • the blind hole 147 is for example arranged in a partition 150 secured to the body 32, in the immediate vicinity of the anchor 143, and has a bottom face 149 plane, perpendicular to the axis 148, and a peripheral face 151 cylindrical of revolution around axis 148; additionally, the finger 146 is delimited by an outer peripheral face 152 which is cylindrical of revolution around the axis
  • the stud 145 is carried integrally by the finger 146, perpendicular to the axis 148, and passes through the partition 150, from the hole 147 and towards the anchor 143, via a light 157 fitted in the partition 150, with an oblong shape parallel to the axis 148; parallel to this axis, the lumen 157 has sufficient dimensions so that, from its position of immobilization of the anchor 143 illustrated in FIG.
  • the stud 145 can perform parallel to the axis 148, jointly with the finger 146 when the latter is released vis-à-vis the inner peripheral face 6 of the sleeve 2, a sufficient stroke to completely release the anchor 143; appropriate sizing is within the scope of the normal skills of a person skilled in the art.
  • the anchor 143 As soon as the anchor 143 is released from the stud 145, it authorizes a controlled rotation of the escape wheel 142 around the axis 143 and of the detonator-carrying wheel 96 around the axis 51, under the spring drive 131.
  • the pinion 140 has a toothing only on a part of its periphery, meshing with the gear train 141 on the one hand when the axis 103 is perpendicular to the axis 1 and, from this orientation, on part of the 90 ° angle of rotation necessary for the passage from this orientation to an alignment orientation of the axis 103 with the axis 1, to establish a rotation regulated by the escapement wheel 142 - anchor 143 assembly during the crossing of this angular travel part, to then completely release the detonator-carrying wheel 96 with respect to the continuation of the rotation around the axis 51 under the action of the spring 131, until axis 103 is aligned with axis 1.
  • the pyrotechnic delay 94 and the clock timer 136 are designed in a manner easily accessible by a person skilled in the art, as to the delays which they must introduce respectively in the initiation of the detonators 112 and 113 via the relays 110 and 111 with respect to percussion of the primer 58 at the crossing of the cam path 12 - 74 by the end 69 of the finger 63 at a sufficient speed and in alignment with the axis 103 with the axis 1 relative to the clearance of the finger 146 vis-à-vis the wall 4 of the sleeve 2, so that the alignment of the axis 103 with axis 1 occurs at the latest before the end of combustion of the pyrotechnic relay 94, taking into account the tolerances allowed in their manufacture.
  • the rotation of the detonator-carrying wheel 96 around the axis 51 relative to the body 32 of the projectile 3 when the axis 103 is aligned with the axis 1 can be stopped by means of any stop system, and for example by coming from a nipple 157, carried integrally by the detonator-carrying wheel 96, projecting on its face 99 parallel to the axis 51 inside the chamber 50, against a counterpart of abutment 158 secured to the body 32 of the projectile 3 inside the chamber 50, in a suitable position that can easily be determined by a person skilled in the art.
  • the igniter 29 is initiated, which itself initiates the pyrotechnic ejection composition 26, which emits gases which accumulate in the expansion chamber 28 passing through the perforations 27 in the wall 24.
  • the projectile 3 begins to move in the direction 73, along the axis 1, inside the sleeve 2.
  • the counterweight 83 causes the end 89 of the finger 88 to retract with respect to the face 55 of the chamber 49 and maintains this retraction at least until the projectile 3 is completely removed from the socket 2.
  • this orientation is reached before ignition of the detonators 112 and 113, and they detonate directly opposite the payloads 46 and 45, respectively, from which they are separated along the axis 1 only by a thinned partition, that is to say mechanically weakened, respectively 258, 259 of the body 32; the two partitions 256 and 259 are destroyed by the shock wave and the fire is transmitted to the two payloads 45 and 46 which ignite simultaneously.
  • the shock wave does not pass directly to the weakened partitions 258 and 259, which are calculated so as not to destroying itself in such a case, so that the transmission of fire does not take place towards payloads 45 and 46; this provides protection against a failure of the pyrotechnic delay 94, leading to a too short initiation time of the detonators 112 and 113, assuming that the ejection was carried out with an acceleration and a speed sufficient to cause on the one hand the retraction of the end 89 of the finger 88 and on the other hand the percussion of the primer 58 by the striker 62 of the part 60.
  • the percussion cannot be perform so that after the expiration of the alignment time of the axis 103 with the axis 100, there can be no ignition of the payloads 45 and 46.
  • This effect is reinforced by the mechanical weakening of the walls 262, 263 delimiting the cavities 43, 44 at the level of the transverse end faces 37, 34 of the projectile body 32 by the notches 260, 261; in fact, this weakening promotes a tearing of these walls 262, 263, in the form of petals, as a priority in comparison with the walls delimiting by elsewhere the cavities 43 and 44 when the payloads 45 and 46 ignite, and this tearing of the walls 262 and 263 longitudinally channels the flows resulting from the ignition of the charges 45, 46, respectively and translates them into symmetrical, antagonistic longitudinal forces , applied to the central section 42.
