Definitions

  • the technical field of the invention is that of containers capable of receiving a propellant charge and more particularly that of containers used in the field of large caliber or tank artillery.
  • Modular cylindrical containers which have been made of combustible material have already been defined. Thanks to their rigidity, such containers are easier to use than traditional powder sachets.
  • Patent FR9101499 describes a container connecting device which comprises on the one hand a sliding ring and on the other hand hook-and-loop fastening means arranged on a front face of the container.
  • Such a device is complex and expensive to manufacture.
  • the means proposed are delicate to implement. Indeed, for the ring to slide it is necessary that the radial positioning of the two containers is correct. However, the attachment means are active whatever the relative radial position of the two containers. This results in a difficulty in positioning and then making the two containers integral.
  • the patent FR1291315 describes a detachable coupling for explosive cartridges, the separation of which is effected by means of a wire or a cord which makes it possible to manually compress an internal elastic ring.
  • the invention thus provides a container connection device which is simple and inexpensive. This device ensures easy connection of two containers before their introduction into the chamber of a weapon and rapid separation of the containers without using an additional element, when it is necessary to remove them from the chamber.
  • the invention also relates to a container which can be made integral with another container at one of its front faces, by means of such a connecting device.
  • the invention can be applied as well to the realization of modular loads as of loads in at least two loads, one carrying the main load and its igniter tube and the other the projectile (and possibly, but not necessarily, a secondary charge).
  • the subject of the invention is a device making it possible to secure two containers at their front faces and comprising a ring mounted in a sliding manner at the level of a first constriction arranged on a first container and which can slide to partially cover a second constriction fitted on a second container, the front end of the ring comprising an annular spout which ensures an axial attachment of the ring on the second container when it comes to cover the second constriction, the spout cooperating with a circular redent carried by a solid ring of the second constriction, a device characterized in that it comprises first means ensuring the detachment of the front end of the ring from the second container when the two containers are placed in a chamber of a weapon, means which include an outer diameter of the ring greater than the outer diameter of the container, the ring being susceptible e to deform radially, when it is placed in the chamber of the weapon, so as to adopt a diameter substantially equal to that of the container, this deformation causing the annular beak
  • the device comprises second means ensuring the attachment of an internal part of the ring with the second container when the two containers are in the chamber of the weapon.
  • the second attachment means of the internal part of the ring comprise a fold arranged on the internal surface of the latter and capable of coming into abutment on a flange carried by the ring secured to the second constriction.
  • the ring will include, at a rear part, a shoulder intended to cooperate with a collar arranged on the first constriction in order to produce an axial stop and will be made of a plastic material of the Polyoxymethylene or High Density Polyethylene or polyamide type.
  • the collar will be part of a sub-ring integral with the first neck, sub-ring on which the ring is slidably mounted.
  • the sub-ring and / or the ring will be made of a plastic material of the High Density Polyethylene or polyamide type.
  • the sub-ring will include an annular stop allowing the axial connection of the ring with the sub-ring in its advanced position, the shoulder of the ring being positioned between the stop and the annular collar.
  • the fold and the flange will each have a conical bearing, the two conical bearing being complementary and intended to cooperate.
  • the invention also relates to a container, in particular for a propellant charge, intended to be made integral with a second container at one of its front faces by a securing device, container characterized in that it comprises at least one constriction arranged in the vicinity of the front face, constriction intended to receive a ring of external diameter greater than the external diameter of the container and which is liable to deform radially so as to adopt a diameter substantially equal to that of the container, the ring being slidably mounted at the constriction, the front end of the ring comprising an annular spout intended to cooperate with a circular step arranged on a ring.
  • the constriction will include a sub-ring intended to receive the ring, sub-ring comprising an annular collar intended to cooperate with a shoulder of the ring.
  • the container comprises at least one constriction arranged in the vicinity of the front face, constricted intended to receive a ring having a circular redent intended to cooperate with an annular spout arranged on a ring carried by the second container.
  • a first container 1a is intended to be made integral with a second container 1b at its front face 2a. The latter will then be in contact with the front face 2b of the second container.
  • Each container comprises a cylindrical envelope 3a, 3b made of a combustible material such as nitrocellulose, cardboard or a cardboard / nitrocellulose mixture.
  • the envelopes are closed by end caps 4a, 4b which are also made of a combustible material.
  • the caps are made integral with the envelopes by gluing at the level of the cylindrical surfaces 5a, 5b.
  • the containers 1a and 1b are shown here partially. They are intended to receive a propellant charge in grains or sticks (not shown).
  • the container 1b carries at its other end a projectile (not shown) which will be made integral with the casing 3b by a connecting ring (for example similar to that described by patent FR8712484).
  • the container carries at its other end a base (not shown) provided with an igniter tube (see for example patent FR9101499 which shows the fixing of such a base on the envelope).
  • the stopper 4b carries a cup 6 with a frustoconical profile which is placed in the center of the front face 2b.
  • the stopper carries a bulge 7 with a frustoconical profile which is placed in the center of the front face 2a.
  • the frustoconical profiles of the bowl 6 and the bulge 7 are complementary and are intended to cooperate with each other to allow relative radial positioning of the two containers before their assembly.
  • Axial openings 22a and 22b are arranged at the front faces 2a and 2b of the containers. These openings facilitate the transmission of flame from one container to another when igniting the propellant charge. They are obstructed, in a known manner, for example by means of combustible sheets (not shown).
  • the end plugs 4a and 4b each carry a constriction 8a, 8b, the maximum diameter D1 of which is less by the order of 10 mm than the external diameter D2 of the container, the diameter D2 of the container corresponding substantially to the internal diameter of a chamber. of a weapon in which it will be placed.
  • the constriction 8a of the container carries it a sub-ring 9 fixed for example by gluing.
  • This sub-ring is made of plastic, for example of the high density polyethylene or polyamide type.
  • the sub-ring 9 carries on its external cylindrical surface 10 an annular collar 11.
  • a ring 12 is slidably mounted on the sub-ring 9. It is also made of plastic material of the polyoxymethylene or high density polyethylene or polyamide type. It has a shoulder 14 arranged at a rear part 13 and a fold 16 at an internal surface and on the side of a front end 15.
  • the shoulder 14 and the fold 16 have a diameter greater than the external diameter 10 of the sub-ring 9, which allows the sliding of the ring on the sub-ring.
  • the shoulder 14 is intended to abut on the annular collar 11 so as to limit the axial displacement of the ring 12 relative to the sub-ring 9.
  • the ring 12 is put in place by elasticity on the sub-ring before gluing the latter on the neck 8a.
  • the ring 12 can no longer be separated from the container 1a, which avoids its loss and simplifies the logistics.
  • the ring 12 comprises an outer bead 17 of diameter D3 which is greater than the diameter D2 of the container of the order of 2 to 3 mm.
  • the ring also includes, at its front end 15, an annular spout 18.
  • the container 1b carries on its neck 8b a ring 19 fixed for example by gluing.
  • This ring is also made of plastic, for example of the high density polyethylene or polyamide type.
  • the ring 19 carries a circular redent 20 intended to cooperate with the annular spout 18 of the ring 12. It also includes a flange 21 intended to cooperate with the fold 16 of the ring 12.
  • FIG. 2 represents the two containers 1a and 1b assembled by the ring 12.
  • the two containers were brought into contact with each other at their end faces 2a, 2b.
  • the bowl 6 and the bulge 7 then ensure the alignment of the containers and thus constitute means ensuring good radial positioning of the two containers.
  • the ring 12 is slid over the sub-ring 9 so as to bring it into contact with the ring 19.
  • a slight forcing makes it possible to hang the annular spout 18 with circular redent 20, which ensures the securing of the two containers.
  • the shoulder 14 of the ring 12 is then found in abutment against the annular collar 11 of the sub-ring 9.
  • the collar 11 thus ensures the axial immobilization of the containers 1A and 1b when the spout 18 of the ring 12 is hooked to the circular redent 20 of the ring 19.
  • the flange 21 has an external diameter substantially smaller than the external diameter 10 of the sub-ring 9 so as not to interfere with the fold 16 during the translation of the ring 12.
  • the material of the ring, the sub-ring and the ring fragments when the propellant charge is ignited under the effect of the gas pressure.
  • zones of embrittlement obtained for example by localized heating or machining.
  • FIG. 3 represents the two containers 1a and 1b assembled by the ring 12 and placed inside a tube 23 of a weapon.
  • the ring 12 When loading the two containers 1a and 1b inside a chamber 24 of the tube 23 along arrow C, the ring 12, which in the rest position has a diameter D3 greater than the diameter D2 of the containers, deforms radially elastic in order to adopt the internal diameter of the chamber 24.
  • the deformation of the ring causes the spout 18 to unhook from the circular redent 20 and then a slight recoil of the ring relative to the containers until the fold 16 comes substantially into abutment against the flange 21.
  • the dimensions of the ring will be defined so that the deformation of the latter by reduction of its external diameter D3 can ensure the release of the attachment of the spout 18 from the redent 20 and the advancement of the fold 16 in the vicinity of the collar 21.
  • Figure 4 shows the two containers 1a and 1b during the unloading phase.
  • FIG. 5 represents the two containers 1a and 1b at the end of the unloading phase.
  • the two containers are thus removed from the barrel chamber of the weapon in a single operation and are found not integral with each other, which allows faster maneuvering, for example in the event of a single exchange. containers or return to storage position after non-use.
  • FIG. 6 represents a modular type container according to the invention.
  • This container made of combustible material, is intended to be assembled with other containers which are completely identical to it in order to constitute a propellant artillery charge.
  • It consists of a combustible envelope 3, closed at one end by a plug 4a which carries a first constriction 8a and at the other end by a plug 4b carrying a second constriction 8b.
  • the first constriction 8a carries a sub-ring 9 and a ring 12.
  • the second constriction 8b carries a ring 19.
  • the envelope would then be closed at its ends by plugs 4a, 4b of the type of those shown in FIG. 1.
  • the cylindrical envelope was closed by two combustible plugs carrying a constriction.
  • the envelope is shaped in an appropriate mold. This avoids a delicate operation of fixing by gluing the plug on the envelope.
  • weakening zones may be provided on the latter, obtained for example by localized heating or by machining.
  • Figure 7 shows two containers according to a second embodiment.
  • the sub-ring 9 has on its external cylindrical surface 10 and near the collar 11, an annular stop 25.
  • the stop 25 allows the axial retention of the ring 12 when the latter is in the advanced position, the shoulder 14 of the ring having come to be received between the collar 11 and the stop 25.
  • the stop 25 has a chamfer at its rear part which facilitates the passage of the ring 12.
  • the ring can also carry a complementary chamfer (not shown) on the front part of the shoulder 14.
  • Such an embodiment has the advantage of being able to be used in an automatic loading device without requiring the prior assembly of the two containers, only the translation of the ring 12 in the advanced position is necessary. Indeed, the ring being in its advanced position, the container la is put in place in the automatic loading followed by the container 1b. The ring 12 being unable to move back thanks to the stop 25, the container 1b is automatically joined to the container by hooking the spout 18 of the ring 12 on the redent 20 of the ring 19.
  • the collar 21 of the ring 19 has, in this second embodiment, a conical bearing 26 complementary to a conical bearing 27 produced at the rear level of the fold 16 of the ring 12.
  • the two complementary conical bearing surfaces 26 and 27 improve the mechanical strength of the fold back link 16 / flange 21 when the containers are removed. They allow the connection to be maintained during removal as long as the tractive effort is effective.
