Definitions

  • the invention relates to the technical sector of ammunition.
  • the ammunition is for example constituted by a case, one end of which is capable of receiving the projectile, while the other end has a chamber shaped to receive a propellant cartridge.
  • the propellant cartridge is specially designed for the firing of projectiles whose material, diameter and weight are determined to avoid, at short distance, penetration on impact.
  • the projectile generally executed in the form of a large diameter ball, is housed in a cup mounted with free sliding and centered in the bore of the corresponding part of a case constituting the body of the ammunition.
  • This type of ammunition is apparent, for example, from the teaching of patent application FR 8805255, of which the applicant is also the holder.
  • the projectile is made of a material which is not sufficiently flexible, so that the impact surface of said projectile is very substantially limited to the initial surface generated by the volume of the projectile. However, in some cases it is important that this impact surface is as large as possible.
  • the problem which the invention proposes to solve is to design a projectile for ammunition of large caliber firearms, the characteristics of this projectile being determined to obtain, on impact, a much larger surface area than that generated by volume initial of the projectile.
  • the projectile is constituted by a spherical body made of flexible material, determined to delimit, after firing, a very large impact surface.
  • the spherical body is made of polyurethane elastomer and is subjected to a treatment capable of eliminating any effect of viscosity.
  • Another problem which the invention proposes to solve is to give the projectile temporary protection at the time of firing, taking into account the pressure forces exerted and the flexible material used for said projectile, the problem being to be able to guide this projectile until the exit of the barrel while maintaining it in its original form.
  • Such a problem is solved in that the projectile is housed in a cup mounted with free sliding and centered in a bore of the ammunition, said cup being arranged to confer a certain rigidity on said projectile at the time of the shooting.
  • this problem is solved in that the projectile is housed in the bucket by interposing a protective envelope made of waterproof and non-fibrous material and capable of enveloping, in part, said projectile.
  • the latter is constituted by a spherical body constituting an envelope made of flexible, waterproof and deformable material, capable of delimiting an internal volume capable of '' be filled with a liquid or pasty fluid.
  • the projectile is constituted by a body spherical constituting an envelope capable of delimiting an internal volume capable of being filled with a liquid or pasty fluid
  • the material is selected to burst at the moment of impact, to cause, in a concomitant manner, the diffusion of the fluid.
  • Another problem which the invention proposes to solve is to be able to use the weapon in any circumstance, whatever the outside temperature.
  • liquid or pasty fluid is selected to be insensitive to low temperatures.
  • the projectile is housed in a cup in two separate detachable parts, said sealing cup in a recess of the ammunition.
  • the rear part of the bucket has arrangements capable of increasing the rigidity of the latter, while ensuring sealing at the time of firing.
  • the arrangements are constituted by external radial ribs arranged in overflow from the bottom of the case, delimiting, in combination with said case, a sealing bead.
  • Figure 1 is a perspective view of the entire projectile and its receptacle cup, according to a first form of production.
  • FIG. 2 is a view in longitudinal section, showing the projectile housed in the bucket, according to the embodiment illustrated in FIG. 1.
  • FIG. 3 is a cross-sectional view on a larger scale, considered along line 3-3 of FIG. 2.
  • Figure 4 is an enlarged cross-sectional view, taken along line 4-4 of Figure 2.
  • Figure 5 shows the projectile corresponding to the embodiment of Figure 1, at the time of its impact.
  • Figure 6 is a perspective view of the entire projectile and its receptacle cup, according to another embodiment.
  • FIG. 7 is a view in longitudinal section, showing the projectile housed in the bucket, according to the embodiment illustrated in FIG. 6.
  • FIG. 8 is a cross-sectional view on a larger scale, seen along line 8-8 of FIG. 7.
  • FIG. 9 is a cross-sectional view on a larger scale, seen along line 9-9 of FIG. 8.
  • FIG. 10 shows another example of ammunition for a large caliber firearm equipped with the projectile according to another embodiment.
  • Figure 11 is a longitudinal sectional view of one embodiment of the projectile.
  • the projectile according to the invention finds a particularly advantageous application for ammunition of large caliber firearms.
  • Figure 1 shows a non-limiting example of ammunition which comprises in known manner, a case (E) generally in plastic material.
  • a case (E) generally in plastic material.
  • One end of the case (E) has a chamber capable of receiving, for example, a propellant cartridge (C).
  • the projectile (P) is contained in a bucket element (3), mounted to slide freely and centered in the bore in the corresponding part of the case (E).
  • the projectile (P) taking into account the problem posed of increasing the impact surface, can have different embodiments, the bucket (3) being adapted accordingly to each embodiment.
  • the projectile constitutes a spherical body, without excluding other geometric shapes, depending, for example, on the type of ammunition used.
  • the projectile constitutes a solid spherical body (6), made of flexible material, determined to delimit after firing, a very large impact surface (Figure 5).
  • the body (6) is made of polyurethane elastomer.
  • the body (6) is subjected to a treatment capable of eliminating any viscosity effect.
  • the spherical body (6) can be soaked in a talc bath.
  • the body (6) is housed in the cup (3).
  • the bore of the cup receives a protective envelope (5) made of a tight, non-fibrous material, being able to envelop, in part, the projectile.
  • the purpose of this envelope is to protect the projectile at the time of shooting, by preventing it from being crushed under the effect of the pressure of the gases inside the barrel of the firearm considered.
  • the bucket is arranged to impart a certain rigidity to the body (6) at the time of firing.
  • the bottom of the cup (3) has radial external ribs (3a) which, in combination with the body of the said cup, define a sealing bead (3b).
  • the projectile is constituted by a spherical body in the form of an envelope (1) made of waterproof material capable of delimiting an internal volume (1a) capable of being filled with a liquid or pasty fluid (2 ). From this design, two alternative embodiments can be envisaged.
  • the envelope (1) is of a reduced thickness of the order of about a millimeter, being made of any material which is sufficiently elastic and resistant to not burst at the time of impact, while being able to crash and expand in combination with the fluid (Figure 11).
  • the envelope (1) of the projectile is made of a material selected to burst on impact, to cause, concomitantly, the diffusion of the fluid (Figure 6).
  • the envelope (1) is housed in a case (4) in two separate parts (4a) and (4b).
  • the bottom of the case has radial external ribs (4c) shaped to delimit a sealing bead (4d).
  • the envelope can be filled in different ways.
