Definitions

  • the present invention relates to anti-personnel ammunition.
  • Anti-personnel ammunition and other ammunition for soft targets has long been known in the art.
  • Several types of anti-personnel ammunition include a plurality of submunitions in a single casing which are scattered when the casing is opened.
  • a projectile including a plurality of submunitions in the projectile, means for ejecting the submunitions substantially simultaneously from the casing, and means for detonating each submunition in the air at a different time.
  • the means for detonating includes a time delay fuze in each submunition, each time delay fuze having a different time delay.
  • the projectile has a flat trajectory.
  • flat trajectories are considered as a superelevation of not more than approximately 15° between launcher and target.
  • the submunitions are coupled to one another, and the means for detonating includes means for separating one submunition after another from the remaining submunitions, and means actuated by the means for separating for detonating the separated submunition.
  • a method of attacking a target including the steps of shooting a projectile including a plurality of submunitions over the target, substantially simultaneously ejecting the submunitions from the projectile, and sequentially detonating the submunitions.
  • the present invention relates to anti-personnel ammunition including a plurality of submunitions which, while having a flat trajectory is capable of attack from above, so as to eliminate soldiers behind a barrier, in trenches, or lying down.
  • a flat trajectory is a superelevation of not more than approximately 15° between launcher and target.
  • the anti-personnel ammunition is provided with a different time delay for deployment of each submunition, thereby providing deployment over a long area in the line of flight. It is a particular feature of the invention that, due to the method of operation, the submunitions explode or burst above the target. Thus, the effect of a proximity fuze can be achieved by using less expensive time delay or range fuzes, For ease of description, the invention will be described herein with regard to time fuzes for expulsion of the submunitions, which are the most common at present. It will be appreciated, however, that any other fuze can alternatively be used, including a range fuze.
  • the anti-personnel ammunition of the present invention is particularly useful in the following types of weapons: flat trajectory barrel type weapons; rocket-type flat trajectory weapons; cruise missiles and flat trajectory ground to ground missiles. It is particularly useful as a tank shell against infantry targets.
  • Fig. 1 there is shown a schematic sectional illustration of anti-personnel ammunition 10, constructed and operative in accordance with one embodiment of the invention.
  • Ammunition 10 includes a projectile 12 and a cartridge 14.
  • Projectile 12 has a nose 16 and a base 18, with an optional tracer 19.
  • Cartridge 14 includes a primer 15 and propellant 17, as known.
  • a plurality of submunitions 20 are disposed in the projectile 12 and held in place by base 18.
  • a time fuze 22 is disposed in nose 16 and is coupled to an expulsion charge 24 for expelling submunitions 20 from projectile 12 by means of a piston 26.
  • Operation of the ammunition of the present invention is as follows, with reference to Figs. 1 and 2.
  • the tank (or other weapon firing the projectile) measures the range to the target.
  • the range is loaded into time fuze 22, either manually or by means of an electronic setter.
  • the round is fired.
  • time fuze 22 ignites the expulsion charge 24 in the ejection cup. This creates high pressure in the ogive, which pushes the piston 26.
  • Piston 26 transfers the force to the base 18 of the projectile through the submunitions 20.
  • Base 18 of the projectile is sheared, and the submunitions are ejected from the projectile 12, and continue to fly.
  • the detonation of the submunitions can be accomplished in a number of ways (pyrotechnic, mechanical, electronic, and others). Two possible ways are described below, by way of non-limiting example only.
  • Figs. 3 and 4 One possibility, illustrated in Figs. 3 and 4, is that all the submunitions are ejected together from the shell while coupled to one another. After ejection from the projectile, sliders 34 in submunition fuze 32 of the rearmost submunition 30 (closest to the base) are armed. In the remaining submunitions (not shown), the fuzes remain unarmed, each fuze remaining safe because of the submunition attached behind it.
  • the firing pins 36 are free to move, and they initiate the separation delay 38 and the detonation delay 40.
  • the lead charge 48 is detonated, which detonates the main explosive charge 50.
  • the submunition explodes, spraying fragments on the ground and creating a shock wave in the surrounding area.
  • each submunition is released from the remaining submunitions and detonated at a different location along the line of flight of the projectile. Due to the time difference in igniting the detonation delay 40, the length of which is the same as the separation delay 38, each submunition explodes with a delay after the'submunition before it. Due to the speed of flight of the submunitions, explosion at different times results in explosion over different locations. In this way, the explosions are distributed over a desired linear range.
  • the second method involves expelling all the submunitions at one time, but not coupled to one another.
  • sliders 52 in all the submunitions are armed, freeing firing pins 54 in each submunition.
  • Firing pins 54 initiate the explosion delays 56 in all of the submunitions.
  • the lead charge 58 explodes. Explosion of the lead charge 58 explodes the booster 60, and booster 60 detonates the main charge 62.
  • the principle of operation of this embodiment is based on different pre-selected delay times for explosion of each submunition, rather than different initiation times. In each submunition, a different delay is installed, and this causes the submunitions to explode along a desired line.
