Definitions

  • the subject of the invention is a device for supplying a weapon with ammunition, specially adapted for fragile munitions.
  • the loading corridor therefore comprises guide members between which the ammunition is pushed by means of automatic transport.
  • a displacement the lang of the axis is carried out by a repressor comprising a pusher which bears on the ammunition and which moves along a direction parallel to the axis of the latter.
  • the loading corridor generally consists of several parts, for example an integral part of the oscillating machine and a fixed part mounted on the carriage and which can consist of a magazine comprising a series of ammunition locations forming a closed chain , associated with a series of cell trays.
  • the different parts of the loading lane are equipped with ammunition guiding members, it is difficult to correctly wedge them in the loading lane or the shock store to which the ammunition is subjected when the weapon is mounted for example on an armored vehicle can cause a detenoration of the loading lane and even ammunition when these are fragile.
  • ammunition comprising a shell associated with a socket of combustible material that is not very resistant and which must always be well supported over its entire length so that the shell remains integral with the combustible socket.
  • the container consists of two tubes sliding telescopically one inside the other; the inner tube can. thus form a bridge between the magazine and the breech, for the loading of the ammunition and, when it is retracted inside the external tube, to free the space necessary for the retreat of the cylinder head.
  • the wedging pads are constituted by plates fixed to the end of flexible blades, the other end of which is integral with the internal tube, the latter being provided with an orifice for the passage of the plate and of its flexible blade.
  • the magazine must be placed on the carriage and it is then moved away from the cylinder head by a relatively large distance.
  • Such a device is intended for normal munitions and does not ensure their maintenance when they are provided with a combustible case.
  • the subject of the invention is improved provisions enabling its length to be maintained over all its length / not only inside the folded container but also when the container is unfolded and during the movement of the ammunition relative thereto. of them
  • the telescopic container is provided with at least / rows of wedging studs spaced from one another for holding, res. pectively, from the shell and the shell and, after unlocking, each stud is held in the chocking position by its flexible blade and constitutes an elastic support capable of being spread outwards by the passage of part of the ammunition with a larger section than that corresponding to the chocking position, the unlocking of the studs being controlled by successive rows during the movement of the ammunition relative to the outer tube.
  • the device comprises a telescopic container placed in the axis of loading of the cylinder head to form a connection tube between the latter and the magazine, this container being devoid of bottom and constituted itself by an external tube. and an internal tube on which are mounted wedges of the ammunition. This is pushed by a delivery device from the magazine to the cylinder head and guided continuously by the studs of the magazine container then of the connecting tube which are locked and unlocked in successive rows during the advancement of ammunition.
  • other parts of the loading corridor could be constituted by a telescopic container forming a tube inside which the ammunition is guided by resting on the wedging pads. It is thus possible to separate the different parts of the loading passage, leaving free spaces for the passage of mechanical parts, these spaces being occupied, at the time of loading, by the unfolding of the internal tube.
  • the external tube is provided, for each pad, with an orifice and a notch with sections equal .respectively, to those of the pad and of the flexible blade and whose position the along the container wedged longitudinally with respect to the level of the stud in the folded position by a distance equal to the advancement of the internal tube in the unlocked position, and, for at least part of the studs, the orifice for the passage of the latter is closed by a movable shutter, the opening of which is controlled, for a determined position of the ammunition, by the displacement of the latter in the internal tube.
  • Figure 1 there is shown schematically, in longitudinal section, the rear part of a barrel tube 11 mounted on an armored vehicle 1 and provided with a cylinder head 12, the assembly being fixed on an articulated oscillating mass on the vehicle 1 around a horizontal axis 10 of elevation orientation.
  • the ammunition is placed in reserve in a magazine 2 placed on the rear of the vehicle, and which is shown diagrammatically in section in FIG. 3.
  • the magazine limited by two transverse walls 21, comprises a series of cell trays 22 arranged in pairs on axes 23 arranged in a horizontal plane.
  • the ammunition driven by the nested cell trays form an endless chain.
  • each pair 22 takes care of the ammunition, one at the level of the shell plate and the other at the height of the crimping of the shell.
  • This arrangement is perfectly suited when the ammunition has a metal case and is very rigid.
  • more fragile munitions / like those which have a combustible case l cannot be retained at two points only especially when the gun is mounted on a vehicle subjected to horizontal and vertical accelerations.
  • each munition is placed in a tubular container 3 provided with wedging pads. So like it can be seen in FIG. 3, the cell trays 22, symbolized by crosses in the figure, will not engage directly on the ammunition M but on the periphery of the containers 3 each containing an ammunition. It obviously follows that the diameter of the cells must be enlarged to correspond to that of the containers 3 which is substantially greater than the diameter of the ammunition.
  • each container 3 consists of an inner tube 31 and an outer tube 2 telescopically sliding one inside the other. It is the same for the container 4 which consists of an internal tube 41 and an external tube 42 so as to make the connection with the cylinder head 12.
  • the munition M is held by a plurality of wedging members made up of studs 6 distributed around the munition and over the entire length of the latter.
  • the inner diameter of the inner tube 31 is equal to that of the socket plate M1 of the ammunition M.
  • the ammunition can be held sufficiently by two series of studs 6 placed in two transverse planes spaced from each other so that the studs of one series rest on the shell and the studs of the other series on the socket, near the crimping ( Figure 4) .
  • Each stud 6 is fixed to the end of a flexible blade 61 placed along the outer wall of the internal tube 31, on which it is embedded at its other end. In addition, the stud 6 penetrates towards the interior of the container 3 through an orifice 34 formed on the wall of the internal tube 31.
  • the stud 6 protrudes towards the outside of the tube 31 by a height e corresponding to the interval existing between the walls of the tubes 31 and 32 and therefore comes s' press against the inner wall of the tube 32 which locks it in this position.
  • the total height h of the stud 6 is determined, as a function of the position of the stud along the munition, so that it penetrates towards the inside of the tube 31 over a distance which, in this plane, corresponds to the difference in diameter between the ammunition and the tube 31.
  • the studs 6 are locked and ensure the timing of the munition, the latter being obtained in good conditions if there are in each support plane / three studs centered in axial planes angularly spaced by 120 °. In these axial planes are centered three slots 35 formed in the wall of the external tube 32, one of these slots being shown in FIG. 6. These slots allow the studs 6 to be unlocked for certain relative positions of the tubes 31 and 32, as we will see it with reference to FIG. 11 which represents the successive stages of advancing an ammunition from a container 3 from the store to the container 4. For simplicity, the positions are shown only in FIG. 11 relative internal and external tubes of the container 3 and the pads which are placed in the plane of the figure.
  • Figure lla corresponds to Figure 4, the pads 62 and 63 being locked.
  • the pads 62 and 63 being locked.
  • the slot 35 extends opposite the studs 62, the latter, however, in this position, have a width greater than that of the slot and remain locked.
  • the studs 63 are placed in front of a solid part of the external tube 32.
  • the elongation of the telescopic container is produced by the displacement member of the ammunition which is supported thereon and at the same time causes the advancement of the internal tube 81.
  • This displacement member can be constituted in a conventional manner by a repressor 5 comprising an endless chain provided with a stop 51 which moves in a direction parallel to. the axis 30 of the munition M taking support on the socket plate Ml. To this end, the stop 51 slides in two superimposed slots 33 formed in an axial plane on the tubes 31 and 32 ( Figure 4).
  • the magazine 2 is provided with a single repressor 5 dvec which must wedge the slots 33 of the tubes when arriving in the sliding position. This is why the inner tube 31 is guided longitudinally on the outer tube 32 and the latter is closed by a bottom 36 which carries two guide pins 37 sliding in a closed groove 26 formed on the bottom 21 of the magazine 2 and preventing the containers 3 to turn on themselves.
  • the repressor 5 causes the ammunition M to advance by means of the stop 51 which rests on the socket plate M1 and at the same time drives the internal tube 31 thanks to an eclipsable stop 311 shown in FIG. 6.
  • the cartridge tray the ML rests on the stop 311 which is pivotally mounted on the tube i n t e r-ne 3 1 so as to tilt and release the tube 31 when it encounters, there is a wedge 321 fixed on the external tube 32
  • a stop 310 fixed on the tube 31 and sliding in a slot 320 of the tube 32 is stopped by the bottom of the slot 320 and blocks the tube 31 in this position shown in FIG. 11b which ensures continuity with the container 4.
  • each pad 62 is placed in front of an orifice 38 disposed at the end of the slot 35 and of section equal to that of the pad; it is then no longer locked and can move outwards by opposing the elastic resistance of the blade 61.
  • the stud 63 placed on the rear and of width less than that of the slot 35 comes stand in front of the rear part of it and is therefore also unlocked.
  • the munition is supported in an elastic manner by the two series of studs 62 and 63.
  • the repressor 5 continues to advance the munition, the latter slides along the studs which, maintained by the elastic blades 61, can move aside from the crimping and the Ml socket plate.
  • the munition continues to advance while penetrating inside the internal tube 41 of the container 4 and, in position d, comes to rest on studs 64 placed at the rear of the container 4 to take charge of the socket M3. In this position, the studs 64 are locked, the two tubes 41 and 42 of the container 4 being folded one inside the other.
  • the socket plate M1 then passes over the studs 62 which, being unlocked, move apart to let it pass and the ammunition completely penetrates into the container 4, in position (e).
  • the ammunition leaves the store while remaining guided by elastic studs inside a continuous tubular conduit.
  • the container 4 shown in FIG. 7 is likewise provided with elastic studs for wedging the ammunition.
  • the container 4 provides the connection with the breech 12 of the barrel, it is essential that at the time of unloading, the munition is placed exactly in the axis (13) of the tube.
  • the vertical accelerations to which the vehicle is subjected could cause a slight displacement of the axis of the ammunition. This is why it is preferred to use the locking means shown in FIGS. 8, 9, 10.
  • the container 4 is provided with four series of studs spaced from one another.
  • the studs 64 which take into account loads the socket M3 on arrival of the latter in the container and on the other hand, at the front thereof, studs 65 which guide the rear part of the socket when the ammunition leaves the container 4 to penetrate completely in the cylinder head 12.
  • the internal tube 41 advances, at the same time as the ammunition, by a length 1 determined by the length of a longitudinal slot 420 formed on the rear of the tube external 42 and in which slides a stop 410 integral with the internal tube 41.
  • a length 1 determined by the length of a longitudinal slot 420 formed on the rear of the tube external 42 and in which slides a stop 410 integral with the internal tube 41.
  • all the pads of the container 4 are placed in front of orifices 46 formed in the external tube 42 and which therefore allow the pads 6 to move towards outside.
  • each orifice 46 is closed by a shutter 7 placed at the end of an arm 71 articulated around a pivot 72 centered on an axis passing through the median plane of the corresponding stud 6 and mounted on a support 73 secured to the outer tube 42 of the container 4.
  • the support arm 71 is extended by a control arm 74, the assembly forming a bent lever, so that the arm 74 extends towards the axis of the container to interpose on the passage of the stop 53 of the repressor 52 associated with the container 4.
  • the stop 53 advances in the direction of the arrow, it pushes on the arm 74 which controls the pivoting of the arm 71 and the opening of the window 46 allowing the unlocking of the corresponding stud 6.
  • the stages of operation of the container 4 are shown diagrammatically on the Figure 12.
  • the latter by means of an eclipsable stop, drives with it the internal tube 41 until the latter comes into abutment in the position of Figure 12
  • the internal tube 41 then makes the connection with the breech 12 and, as indicated, all of the upper studs are unlocked, providing elastic support for the ammunition all along its upper generatrix.
  • the middle of the container 4 only the upper stud 63 is unlocked, since the two lower studs are placed in front of openings 46 which remain closed by the shutters 7.
  • the studs 65 which are placed at the front of the internal tube 41 remain locked during most of the movement of the ammunition inside the tube 41. Their position is determined so that, at the moment when the projectile enters the barrel tube, that is to say substantially in the position the front part of the socket M3 rests on the locked studs 65 which thus maintain the alignment of the ammunition in the axis of the tube and allow its penetration.
  • the studs 63 are located near the rear part of the socket.
  • the stop 53 of the repressor 52 then controls the pivoting of the shutters 7 and the opening of the orifices 46 by pressing on the lever 74.
  • the lower studs 63 are then unlocked and the relative position of the stop 53 and of the socket plate M1 relative to the stud 63 at the time of unlocking is determined by the length of the arm 71.
  • the pads 63 thus unlocked therefore move apart to allow the bushing plate M1 to pass and the repressor then introduces the ammunition into the tube 11 of the barrel.
  • the stop 53 of the repressor comes to lock on the bottom 411 of the slot 412 formed in the internal tube 41 for the passage of the stop 53 of the repressor.
  • the internal tube 41 then advances by a distance 1 ′ and the studs 65 are placed in front of orifices 54 placed at the end of the outer tube 42. They are then unlocked and can therefore move apart to allow the bushing plate M1 to pass when it enters the cylinder head 13 .
  • the ammunition is always guided and the unlocking of the studs 63 prevents the ammunition from tilting relative to the axis of the container and therefore allows its introduction into the tube 11 of the barrel without risk of misalignment.
  • the container 4 During the introduction of the ammunition into the breech 12, the container 4 must obviously be placed in the axis of the barrel but if it remains in this position during the firing, it must be moved back with respect to the breech corresponding to the retreat of the barrel caused by the shooting. This does not present a serious drawback given that the distance 1 of advancement of the internal tube can be adjusted to take account of this additional distance due to recoil and to guide the ammunition as far as the breech, as is the case. shown in Figure 12.
  • the container 4 can be placed on a pivoting frame allowing it to move away from the axis of the barrel outside loading periods.
  • FIGS. 1 and 2 which advantageously comprises two containers 4a and 4b placed respectively on either side of the plane of symmetry B passing through the axel10 of the barrel.
  • Each of the containers 4a and 4b, associated with a repressor 52, is mounted on a cradle 8 articulated around an axis 80 on a fixed support 81 and the tilting of which can be controlled by a jack 82 whose body and rod are articulated respectively on the cradle 8 and the support 81.
  • the two axes 80 are arranged symmetrically on either side of the vertical plane of symmetry P of the mount so that, in the folded position of the jacks 82, the two containers 4a and 4b are aligned with two containers 3a and 3b placed respectively in two trays 24 and 25 of the magazine 2 and that, by extension of the jack 82, one or the other of the containers 4a and 4b comes to center on the axis 13 of the cannon.
  • one of the containers for example 4a can be loaded with a muni tion from the corresponding container 3a while the other container 4b introduces into the tube the ammunition it contains.
  • the rate of fire can be increased.
