Definitions

  • the present invention relates to spinless subammunition projectiles of the type of the mortar bombs or warheads, in which the submunitions are disposed in parallel layers, and more particularly to a device for the mutual drawing away of the submunitions once they have been ejected from the projectile in which they were contained.
  • the device for mutually drawing away the submunitions according to the invention is characterized in that it comprises at least one flat spring for each subammunition layer, said spring being disposed under preloaded conditions among the submunitions, in contact at least with some of them, and being adapted to stretch out when the submunitions are ejected from the projectile thus drawing away ra dially the submunitions from one another.
  • a subammunition projec tile of the spinless type, provided with the device for the mutual drawing away of the submunitions according to the invention.
  • the submunitions 2 are disposed in five layers, each layer consisting of three submunitions 2.
  • the submunitions of each layer are kept in position by three spacer elements 3, generally of plastic material shaped so as to mate the outer surface of the submunitions 2 and the inner surface of the shell of the projectile 1.
  • These elements 3 are not indispensable and anyway we will consider them as a part of the shell of the projectile 1 and not as a part of the de vice for the mutual drawing away of the submunitions 2.
  • a flat spring 4 Disposed between the submunitions 2 of each layer is a flat spring 4, in the preloaded state, shaped as illustrated in Fig. 2, where the spring 4 encompasses almost completely the uppermost submunitions and partial ly the other two lower submunitions.
  • This spring 4 is nothing but a piece of spring steel strip and has nor mally a constant width and thickness. It may, as well, however, for particular requirements, have a variable width: and/or thickne ss.
  • the springs 4 are disposed normally substantially in the central portion of each layer of submunitions 2 even though it is not impossible that, in order to ob tain particular effects, f.e. a spin of the submunitions, this position may be not central.
  • the spacer elements 3 While not indispensable for the operation of the devi- oe according to the invention, the spacer elements 3 have on their concave faces, turned towards the submunitions 2, grooves adapted to receive the spring 4.
  • the action of an ejection charge intervenes which is normally enclosed in the tip 5 of the projectile 1.
  • the action of this ejection charge causes the tail 6 of the projectile 1 to detach and ejects successively the various layers of submunitions 2 from the rear side of the projectile 1.
  • the spring 4 is free to act, whereby, because of the action of the spring, the various submunitions are thrown radially with respect to the tra jectory of the projectile 1.
  • the first steps of the stretching out of the spring 4 and of the mutual drawing away of the three submunitions forming one layer are shown diagrammatically in Fig. 3, in which, for the sake of clearness, the longitudinal dimensions of the spring 4 have been partially altered.
  • the arrows of Fig. 3 indicate the projection directions of the individual submunitions under the action of the sprig 4.
  • Fig. 4 is a side view, looking from the bottom of the drawing sheet, of the sole spring 4 at the same instant shown in Fig. 3.
  • the device according to the invention can be also used in subammunition projectiles provided with a spin in which the effect of the centrifugal force is insufficient to obtain the desired distribution of the submunitions on the ground.
