Definitions
- the present invention relates to projectiles, of the sub-calibrated type, and it relates, more specifically, to such projectiles intended to have high firing precision and high terminal efficiency.
- the present invention aims to propose a new projectile able to have a high impact energy, to have a certain firing precision and to develop a high terminal efficiency, without using an on-board explosive charge.
- the invention is, more specifically, directed towards a sub-calibrated, perforating and fragmentable projectile, which can be produced at a low cost price, by machining and assembly in automated lines, which is of a safe handling after execution and which surely combines the qualities of high impact energy, shooting accuracy and high terminal efficiency.
- the projectile according to the invention is characterized in that:
- the body is made up. by a block of dense material, having a frustoconical axial bore whose large base opens in the plane of the front face of the front part of the body,
- the transmission element consists of a tail extending axially from the rear face of the head and comprising at least one frustoconical bearing which is engaged in support in the tapered bore of the body, so as to leave a clearance between the rear face of the head and the front face.
- the body and the head are immobilized in the position of engagement of the tail in the bore.
- Fig. 1 is a sectional elevation, partially cut away, of a first embodiment of the object of the invention.
- Fig. 2 is a sectional elevation, partially broken away, of another embodiment.
- the projectile according to the invention of the under-calibrated perforating type, comprises a body 1 made of a dense material, such as tungsten, tungsten carbide, depleted uranium, etc.
- the body 1 is generally cylindrical and has an axis of revolution x-x *.
- the body 1 has a neckline at its anterior part to delimit an end portion 2 capable of allowing the assembly by crimping or hooping of a ballistic cap 3 made of a malleable material having good characteristics of penetration into the air, such as light alloy or copper alloy.
- the cap 3 is, moreover, used to ensure the maintenance of a head 4 which has an axis of revolution yy 'intended to be placed in alignment with the axis x-x'.
- the head 4 for example frustoconical, is placed in axial abutment in a complementary recess 3a of the cap.
- Other means than frustoconical cooperation could be provided for axially immobilizing the head 4 which is extended, from its rear face 5, by a shank 6 which is engaged in a bore 7 presented axially by the body 1, from of the front face 8 of the terminal part 2.
- the tail 6 can be an integral part of the head 4 or be constituted by an independent part.
- the bore 7 is, in the example illustrated, of frustoconical type, blind, whose large base opens in the plane of the front face 8.
- the bore 7 is complementary to the general shape of the tail 6 which has a shape also frustoconical, of continuous type or, preferably, segmented, constituted by successive frustoconical bearing surfaces 9, 9, 9, 9 of the same angle at the center, alternated with low-cut sections of neck of smaller cross-section.
- the axial immobilization of the head 4, for example by means of the cap 3, is ensured in a complementary relationship between the bore 7 and the frustoconical bearing surfaces 9, so that when the latter are in abutment against the peripheral wall of the bore 7, an interval or a clearance 10, for example between 0.05 and 0.5 mm, is present between the rear face 5 of the head 4 and the front face 8 of the end part 2 .
- the body 1 can advantageously include zones of lesser resistance 11 which can be arranged axially or, preferably, along planes P transverse to the axis ⁇ - ⁇ *. In the case of pluralities of zones of least resistance 11, provision may be made for staggering them equidistantly axially or not. These areas of least resistance 11 can be produced in any suitable manner known in the art.
- the frustoconical bearing surfaces 9 of the tail 6 are arranged so that, in the support position inside the bore 7, at least some of the bearing surfaces 9 are located in or substantially in the planes P of at least some of the zones 11 of least resistance.
- the projectile, of the fragmentable penetrating shell type described above, is characterized by a static state devoid of explosive charge and having, consequently, a great safety of realization, assembly and handling.
- the production of the projectile, in sub-calibrated form, provided with the cap 3, corresponds to a perforating projectile having good impact energy and shooting accuracy characteristics.
- the projectile according to the invention has, in this way, a high terminal efficiency due to its fragmentation upon impact, which makes it possible to combine the characteristics of firing precision and terminal efficiency by using only a piercing and fragmentable type projectile.
- Fig. 2 shows an alternative embodiment in which the tail 6 has two bearing surfaces 9. and 9, intended to cooperate with the frustoconical bore 7 which is extended by a cylindrical bore 12 extending axially inside the body
- the head 4 is mounted, as said previously, so as to place the bearing surfaces 9 .. and 9-, bearing against the frustoconical bore 7, while leaving the clearance 10.
- the mounting of the head 4 is, however, carried out after having disposed, inside the bore 12, a block 13 of radially deformable material when it is subjected to radial compression, such as in rubber. Editing is also performed so that the tail 6 is extended by a cylindrical end portion 14 responsible for being kept in contact with the corresponding transverse face of the block 13.
- the cylinder 14 can be constituted by an independent part or, again, by an extension of the tail 6 extending beyond the frustoconical range 9 ? .
- the operation of the projectile at impact is of the same order as that described above, due to the presence of the game 10. Indeed.
- the relative displacement of the body 1 relative to the head 4 results in a forced engagement with effect oe corner of the ranges 9 .. and 9-, inside the frustoconical bore 7, locally subjecting the body 1 to stresses radial.
- the depression of the tail 6 pushes the cylinder 14 is loaded so to exert axial constraint on the block 13, mania r e to cause straining radial of the body part 1, possibly intersected by the minus one of the transverse planes of a zone of least resistance 11.
- the radial constraints, locally imposed on the body 1 cause the fragmentation of the latter, simultaneously with the perforation of the target via the head 4.
- the invention is not limited to the examples described and shown, since various modif cations can be added without departing from its scope.
