Description
s Appln.No. 41602/3 CANISTER FOR EXPLOSIVE FIN-STABILIZED PROJECTILES \ INCLUDING A PLASTIC BODY fin-stabilized projectile (hereinafter referred to as proj The invention re in which there is housed separately from the explosive charge an amount of fragments, e.g. balls, metallic pieces and the like, the proj ectile—p eJ-e - -l-^-redt-tg—a—g-r-e ade , ajtjicularly a gre..ade_f.or fi ring—f-r-om—a-mor-ta- .
Various types of such projectiles are known in themselves. The fragments are generally surrounded by an outer casing or sleeve, usually of metal. In such an arrangement the outer casing is of a certain strength and in many cases is of considerable wall thickness. Such a metal casing severely curtails the range of the fragments released by the explosion, as the latter must be driven through the bursting metal casing. Part of the kinetic energy is absorbed in shattering and breaking through the casing.
The purpose of the invention is to provide a projectile of the aforementioned type, in which the fragments are held and contained in a much simpler way, so that they are directly exposed to the effects of the detonation. The exploding projectile, in which fragments are provided separately from the explosive charge is characterised according to the invention in that the projectile has an inner, generally tubular steel casing containing the explosive charge and surrounded by a body of plastics material in which the fragments are embedded, the peripheral surface of the plastics body forming the outer surface of the projectile body. In this case the body consisting of plastic* and containing the embedded fragments has, at or near the peripheral surface, a surrounding continuous layer of a fibre fleece or the like.
In an explosive projectile designed in this manner, the effects of the detonation on the fragments are utilised to a much better degree. The plastics body, which is not restricted on its outer surface by a casing or the like, presents practically no hindrance to the dispersal or scattering of the fragments by the detonation whereby the coverage of these fragments is improved. The plastics body ceases to exist under the force of the detonation so that the force is optimally transformed into kinematic energy of the fragments and a maximum predeterminable effect is guaranteed.
The fleece or net made of fibres or the like provided on the peripheral surface of the plastics body, increases the mechanical strength of the grenade, particularly on the peripheral surface corresponding to the grenade's calibre, and coming into contact with the mortar's barrel wall when fired. It is however thin enough to avoid hindrance to the acceleration of the fragments, e.g. balls or the like, during detonation. The result is an explosive projectile, in which the plastics body carrying the embedded fragments Xs B333X effectively pi'otected against accidental external damage without reduction in the effectiveness of the kinetic energy for throwing out the fragments.
Fibres of textiles, glass and/or metal or the like can be provided in a random arrangement in the fleece or net embedded on the plasties body.
According to a further feature of the invention, the peripheral surface of the plastics body, at the point of largest diameter of the grenade, can have an embedded ring of a predetermined thickness, in which guide-elements known in themselves such as annular grooves or the like are provided. This can entail an annular guide ring, such as is necessary for the rifling and/or gas sealing. In this way the necessary function of the projectile as it passes through the barrel is also assured. Such a ring or band is incapable of lessening to any appreciable extent the other effects of the plastics body. The ring or band may also be made of plastics, and has on its other periphery the required profile, e.g. annular grooves and the like.
The pre-formed plastics* and/or metal ring or band or the like, appropriately formed, can be placed directly into the plastics body during the casting process. In this case the fleece layer and the ring or band advantageously form an integral unit. The procedure can however be such that the guide elements such as annular grooves and the like are arranged directly on the fibre-fleece layer reinforcing the plastics body at its periphery. This can be achieved by appropriate moulding of the grooves etc .
The plastics body is preferably moulded directly on to the inner steel casing, in such a way that it as protected against separation from the inner casing containing the charge. The substantially annular plastics* body can however be moulded separately and pushed on to the casing containing the charge. In the case of a mortar grenade, the plastics body is of a cylindrical, pointed, arcuate or toric outei' contour. In the case of other projectiles, the. plastics body can be in the form of a disc, of a thick ring or the like, in the centre of which the casing containing the charge is located.
The invention will now be described in more detail with reference to the drawing, which illustrates a mortar grenade by way of example .
Fig. 1 shows a mortar projectile according to the inventio in partial front view and in partial section; and Fig. 2 shows a cut-out section of the mortar projectile in Fig. 1, a guide-ring or the like being shown embedded in the plastics body.
The mortar projectile or grenade 1 is a fin-stabilised projectile consisting of a main body 2, a forward transitional part 4a with a head igniter 3, a rear transitional part 4b and a tailpipe 5 with guide-fins. The projectile is provided with a preferably tubular inner member 6 of steel or aluminium containing an explosive charge 6'. Member 6 i connected to the forward and rear parts of the projectile in an appropriate way, e.g. by screw connections. The fragments 7, e.g. metal pieces, steel balls and the like, are embedded in a body 8 of .s.o.lid synthetic resin or the like, the fragments 7 being uniformly distributed in the resJLn-,mass . Plastic* body 8, with fragments, is formed as a unitary structure. The resin mass of body 8 directly ^forms the outer surface of the projectile A layer 9 of randomly-arranged or woven fibres can advantageously be provided directly under or on this outer surface. These fibres may be of inorganic or synthetic substances, or even of metal or the like. The fibre-fleece layer is set into the plastics body 8 during the casting process. Instead of a fibre-fleece layer, a net can be set on or near the peripheral s*urface of plastics body 8. The net, like the fibres of the fleece layer, may consist of textiles, glass and/or metal. Guide elements such as annular grooves or the like may be provided in layer 9.
In the region of the calibre diameter of the projectile, an independent ring 10 of a predetermined thickness can be embedded in the plastics: body 8 or the fibre-fleece layer, or in the net, said ring 10 having known guide elements 11 on its peripheral surface. Guide-ring 10 can form an integral unit with the plastic* body 8 or the fleece layer 9 or the net. The metal or fibre net 9 can consist of several parts and need not pass underneath the ring 10.
Instead of an independent ring 10 or band for the guids elements, the region of maximum diameter of the projectile or the like can be additionally reinforced by one or more fibre-fleece layers or nets, so that it is possible to arrange the guide-elements 11 such as annular grooves and the like directly in the plastics body 8 or fleece layer. This region, provided with the guide-elements, has only restricted longitudinal dimensions compared to the plastic* body 8, so that the effect of free dispersal of the fragment provided by plastics body 8, is practically unimpaired.
The ring or band 10 can also be itself made of plastics or synthetic resin.
In the example of a mortar grenade shown, the plasticK body 8 is designed as a pointed arcuate tubular member. In order to make up the grenade, the body 8 is moulded or thrus on to the inner member 6 in such a way that it bears against the transitional part before the head part is attached there Such plastics bodies with embedded fragments can also be provided in other projectiles, e.g. conventional grenades fired from cannon, or in bombs, land mines and the like.
Such a plastics: body can have any suitable shape; it may be formed as a disc or a hollow prism, and may have any externa contour. The plastics body can also be made up of two parts fitting one into the other or secured to one another in any other suitable way.
