  • a hollow-charge projectile may consist of a projectile body containing a shaped charge retained by a typically conical insert, a detonator spacing tube being fitted at the forward end of the body and a detonator case being fitted at the rearward end.
  • the detonator spacing tube causes detonation to occur at the correct distance of the insert from the target, and this tube is therefore of a specific length. Since hollowcharge projectiles should, as far as possible, be prevented from spinning, they are often provided with stabilizing vanes.
  • the carrier projectiles may be fired with or without spin.
  • carrier projectiles containing a number of hollow-charge projectiles are fired.
  • the subsidiary projectiles are ejected from the carrier projectile, for example by detonating a charge contained in the carrier projectile, whereupon the detonators of the subsidiary projectiles become live.
  • These subsidiary projectiles then continue to travel within a certain zone of scatter and detonate individually upon impact.
  • the object of the present invention is to further improve utilization of the space within a carrier projectile.
  • a hollow-charge subsidiary projectile for firing by means of a carrier projectile consists of a body which contains a shaped charge and at the front end of which is disposed a detonator spacing tube and at the rear end of which is a detonator case having stabilizing vanes which can be'folded inwards, wherein the space directly in front of the charge is so shaped and dimensioned that it can accommodate at least a part of the rear end of a further subsidiary projectile of like shape.
  • the subsidiary projectiles can be nested one within the other since the space that is defined by the front of the charge can be used for accommodating a part of the rear of an adjacent subsidiary projectile.
  • the inside diameter of the substantially cylindrical detonator spacing tube which is open at the front is made greater than the outside diameter of the projectile body and of the detonator case with the inwardly folded stabilizing vanes.
  • each of the subsidiary projectiles preferably has a shoulder at its forward end against which a rear shoulder of the next projectile bears. As will be explained later, this arrangement can be achieved by means of various constructions.
  • the arrangement may be such that the detonator spacing tube is slidable telescopically over the projectile body against a spring force, and the subsidiary projectiles in the carrier projectile bear against each other by the front and rear edges of their bodies.
  • This arrangement is particularly advantageous when there are only a few subsidiary projectiles disposed one behind the other, since the foremost projectile can be fitted in the telescoped condition and a further saving in space is effected.
  • the spring force is preferably applied by a helical spring within the front part of the projectile body, the inside diameter of the spring being greater than the greatest outside dimension of the detonator case with the stabilizing vanes folded inwards.

  • FIG. 2 is a longitudinal cross-sectional view similar to FIG. 1, but showing modified form of the hollowcharge subsidiary projectile;
  • FIG. 3 is a longitudinal cross-sectional view similar to FIG. 1, but showing still another modification of the hollow-charge subsidiary projectile.
  • the hollow-charge subsidiary projectile shown in FIG. 1 has a body 1 with a hollow charge 2 accommodated therein, an insert 3 being fitted forwardly of the charge. Secured at the rear end of the projectile body 1 is a detonator case 4 which contains a detonator, not shown in detail, and on the exterior of which are fitted hinged stabilizing vanes 5.
  • a substantially cylindrical detonator spacing tube 6a Disposed at the forward end of the projectile body 1 is a substantially cylindrical detonator spacing tube 6a which is open at the front and the inside diameter of which is greaterthan the outside diameter of the projectile body 1 and of the detonator4 when the stabilizing vanes 5 on the case of the latter are folded inwards.
  • a further subsidiary projectile is shown in dot-and-dash lines in front of the above-mentioned subsidiary projectile, the rearward end of this second subsidiary projectile being accommodated within the detonator spacing tube 6a, and the detonator of said second projectile projecting into the projectile body 1 so that it lies close in front of the insert 3.
  • the detonator spacing tube has, near its rearward end an internally shouldered rim 7, and that the length by which the detonator spacing tube 6a extends over the projectile body 1 is such that the internally shouldered rim 7 of the next subsidiary projectile can bear on the forward edge of detonator spacing tube 6a; it will be understood that the detonator spacing tube 6a must be rigidly secured to the projectile body 1 and should also be sufficiently stable to enable the forces due to inertia to be transmitted to the next subsidiary projectile when a first projectile is fired and ejected from the carrier projectile.
  • the subsidiary projectile illustrated in FIG.- 2 also comprises a body I with a hollow charge 2 and insert 3, and a detonator case 4 and stabilizing vanes 5.
  • the projecting body is here provided with a collor 8 against which bears a thin-walled detonator spacing tube 6b.
  • each of the subsidiary projectiles is supported by an internally shouldered rim 10 at the rear end of the projectile body 1, and each such rim can be supported on the front edge 11 of the subsidiary projectile disposed rearwardly thereof.
  • the detonator spacing tube 6b it is not necessary for the detonator spacing tube 6b to be of particularly stable form since it does not transmit the ejection force, and thus a certain saving in weigh can be achieved.
  • FIG. 3 The arrangement seen in FIG. 3 is based on a somewhat different principle.
  • the detonator spacing tube 60 is slidable telescopically over the outer periphery of the projectile body 1 which, as in the embodiments shown in FIGS.
  • the helical spring 12 is so dimensioned that its inside diameter is greater than the outside diameter of the detonator case 4 including the inwardly folded stabilizing vanes 5, as shown in broken outline in FIG. 3.
  • the detonator spacing tube 6c is provided with two elongated slots.
  • Slot 13 extends axially along tube 60 and has at the lower end an end portion (not shown in the drawing) which extends tagentially with respect to tube 60.
  • the other slot has no reference numeral but is shown in solid lines at the end of spacing tube 60 adjacent the next projectile, shown in dash-dotted lines. This latter slot extends helically about spacing tube 6c and is provided with a similar tangential end portion at its lower end (not shown in the drawing).
  • spring 12 The ends of spring 12 are both bent outwardly. One end extends through body 1 where it is fixed and into slot 13; it acts as a guide member during the forward torque-biased; its free end projection extends into the other slot and may exert a rotational movement upon release once the projectiles separate. Said rotational What is claimed is:
  • a hollow-charge subsidiary projectile for firing by means of a carrier projectile the subsidiary projectile consisting of a body which contains a shaped charge and at the front end of which is disposed a detonator spacing tube and at the rear end of which is a detonator case having stabilizing vanes which can be folded inwards, wherein the space directly in front of the charge is so shaped and dimensioned that it can accommodate at least a part of the rear end of a further subsidiary projectile of like shape.
  • a subsidiary projectile according to claim 2 wherein the projectile body is rigidly connected to the detonator spacing tube and has at that end adjacent to the detonator a rim adapted to be supported on the forward edge of the body of a similar subsidiary projectile disposed to its rear.
  • a subsidiary projectile according to claim 2 wherein the detonator spacing tube can be pushed telescopically over the projectile body against a spring force, and the projectile bodyis adapted to be supported on the forward edge of the body of a similar subsidiary projectile.
  • a subsidiary projectile according to claim 5 wherein a helical spring is fitted in the forward portion of the projectile body, the inside diameter of the spring being greater than the greatest outside dimension of the detonator case with the stabilizing vanes folded inwards.
