BACKGROUND OF THE INVENTION

Anti-personnel ammunition and other soft targets ammunition have long been known. Different types of anti-personnel ammunition include multiple sub-missiles in one cartridge, which are dispersed when the cartridge is opened.

U.S. Pat. No. 3,956,990 discloses anti-personnel ammunition comprising axially arranged layers of small arrows stabilized by ribs in the projectile shell, fired from tanks on a flat flight path. Due to the flat flight path, this ammunition is not effective against soldiers behind any shelter, soldiers in trenches, firing positions or trenches, or soldiers on a diverted rear slope. Its effectiveness against lying soldiers is limited.

It is also known anti-personnel ammunition with lighter with time delay, which explodes in the air. This ammunition has a very small coverage area in the longitudinal direction. The main errors that occur with this ammunition, namely the firing direction errors, with little prospect of hitting the target, in particular targets in the form of persons who are difficult to detect and cannot be accurately targeted for range adjustment.

In addition, explosive missiles with percussion lighter are ripened. These missiles are triggered by the ground impact and do not have an impact on the ground.

-2 Ability to attack from above. Due to their flat flight path, their accuracy in hitting the target is very low.

Thus, there is a long-term need for an anti-personnel munition that contains many sub-missiles and has a flight path but which is capable of being hit from above, and it would be highly desirable to have ammunition that works similar to a proximity sensitive lighter .

DETAILED DESCRIPTION OF THE INVENTION

The invention relates to anti-personnel ammunition comprising partial charges which are capable of attacking from above, although having a flat flight path, to eliminate soldiers behind an obstacle, such as in trenches or lying down. As mentioned above, the speedway is a track with an elevation of no more than 15 ° between the launcher and the target.

The anti-infantry ammunition is equipped with different time delays for the deployment of each partial charge, thereby ensuring deployment over a long flight area. It is a particular feature of the invention that, due to the mode of operation, the sub-missiles explode or spread over the target. This gives the effect of distance lighters (susceptible to lighter-than-average lighters). · · · «« «« «« «« «« «« «« «« ·

-5Near target) when using less expensive delayed or flight path timed lighters. For ease of description, the invention will be described for the use of time lighters to eject partial charges that are currently the most common. It will be appreciated, however, that it is alternatively possible to use any other lighters, such as flight path timed lighters.

The anti-infantry ammunition according to the invention is particularly suitable for the following types of weapons: trajectory guns, flat-rocket missiles, missiles and ground-to-earth missiles. Particularly suitable as a tank grenade against infantry targets.

FIG. 1 is a schematic cross-sectional view of an anti-personnel missile 10 constructed and operative in accordance with the present invention. The bullet 10 comprises a projectile 12 and a cartridge 14. The projectile 12 has a tip 16 and a base 18, with a possible stop sign 19. The cartridge 14 comprises a firing charge 15 and a propellant explosive 17, as is known. A plurality of sub-missiles 20 are held within the projectile 12, held together by the base 18. The time lighter 22 is disposed at the tip 16 and is connected to the ejector cartridges 24 to eject sub-projectiles 20 from the projectile 12 by the piston 26.

The ammunition of the invention operates as follows, as explained with reference to FIGS. 1 and 2. A tank (or other weapon that fires a projectile) measures the target distance. The distance is introduced into the time lighter 22, either manually or by an electronic adjustment device. The missile detonates. When the time comes when the missiles 20 are to be ejected, the firing 22 fires the ejector charge. 24 in the ejection cup. This creates a high pressure at the tip of the projectile, which presses on the piston 26. The piston 26 transmits force to the projectile base 18 through the projectile sub-missiles 20. The projectile base 18 slides and the projectile 12 is ejected from the projectile 12 and continues to fly.

Detonation of partial missiles can be achieved in a number of ways (pyrotechnically, mechanically, electronically and otherwise). Two methods are described below, and are intended only as non-limiting examples.

One of the options shown in Figures 3 and 4 is that the partial projectiles are ejected from the projectile in a state where they are connected to each other. After being ejected from the projectile by the slide members 34 in the time lighter 32, the rearmost bullets 30 (closest to the base) are unlocked. In the remaining partial missiles (not shown), the lighters remain unlocked, with each lighter remaining safe with respect to the partial missile that is attached behind it. Due to the unlocking, the firing pins 36 can move freely and initiate a separation delay 38 and a detonation delay 40.

When the detonation retardant 40 burns out, a detonator 42 explodes, which ignites the separation charge 44. A high pressure is generated in the combustion chamber 46 which causes the outermost missile to detach from the rest of the missiles. As a result of the separation, the security of the lighter closest to the next partial missile is released and its sliding members are unlocked. When the detonation retarder stops operation, detonator 48 is fired, causing the main explosive charge 50 to explode 50. At the end of the retarder operation, the partial missile explodes, with scatter scattering. · ··· • · · · · ·

-To the ground and generating a pressure wave into the surrounding area.

In this way, each sub-projectile is gradually released from the remaining sub-projectiles at various positions along the flight path of the projectile. Due to the ignition time difference of the detonation delay 40, which is the same as the ignition time of the detonation delay 38, each sub missile explodes with a delay after the previous sub missile. Due to the speed of flight of the partial missiles, an explosion at different times results in an explosion above different positions. Explosions are thus distributed over the required linear path segment.

Another method, shown in Figures 5 and 6, is to eject the partial missiles at one time, but without interconnecting one another. Upon ejection from the projectile, the slide members 52 are unlocked in all the sub-shells, thereby releasing the firing pin 54 in each missile. The firing pin 54 initiates the explosion retarders 56 in all the partial missiles. The detonator 58 will explode when the detonator retarder operation ceases. The detonator explosion 58, the booster charge 60, and the booster charge will detonate the main charge 62. The principle of operation of this embodiment is based on different preselected delay times for each sub missile to detonate instead of different initiation times. A different delay is set in each sub missile, causing the sub missiles to explode along the desired line.

It is a particular feature of the invention that the ability to attack from above leads to high efficiency, as shown in Figs. 7a, 7b and 7c, against soldiers lying down, soldiers behind the shelter, in trenches, firing positions or trenches, and soldiers on the rear deflected on a slope against which no solution was found in the airfield weapons.

99 · · Sub-missiles can further correct range sighting errors as at least one of the sub-missiles is likely to explode above the actual target. Due to the attack from the top and compensation of longitudinal errors, great destruction and loss rates are achieved in infantry units.

It will be understood that the invention is not limited to what has been described above by way of example. It is limited only by the following claims.
