A munition in the form of a projectile contains a dart having a body terminating in a front tip and ductile hammer block in the form of a ferrule engaging at least a part of the dart. The dart is formed of sections the diameters of which increase from the back to the front of the dart body, forming support shoulders. A recess in the hammer block has a shape corresponding to the dart body shape received in the hammer block. Hammer block sections form thrust shoulders which engage the corresponding dart support shoulders. When the projectile impacts a target, the thrust shoulders push against the dart support shoulders, causing the ductile hammer block to open and flare out.

The present invention relates to a munition comprising a projectile formed by a dart having a body ending in a tip at its front end and a hammer block in the form of a ferrule which receives at least part of the body of the dart, this assembly being integrated into a cylindrical casing having a diameter corresponding to the diameter of the barrel of the weapon for which the munition is intended.
Such munitions are already known. The aim of the present invention is to develop these munitions in order to increase their effectiveness at the moment of impact of the projectile in the target.
At the moment of impact the opening and progressive flaring of the hammer block results in a thrust exerted on the projectile as far as the last collar which releases the dart. This projectile has a strong stopping power by virtue of a marked opening out of the hammer block and a thorough effectiveness of the dart.
The present invention will be described in greater detail with the aid of the accompanying drawings, in which:
FIG. 1 shows a schematic sectional view of a munition according to the invention,
FIG. 2 shows a view on a larger scale of a first embodiment of a projectile dart/hammer block assembly according to the invention,
According to FIG. 1, the invention relates to a munition comprising a projectile formed by a dart 1 having a body 11 ending at the front in a tip. This dart is accommodated in a hammer block 2 in the form of a ferrule. The dart is for the most part received in the hammer block. The dart extends beyond the hammer block at its tip 12 and possibly its rear end. This assembly composed of the dart 1 and of the hammer block 2 is accommodated in a cylindrical casing 3. This casing 3 has a diameter corresponding to that of the barrel of the weapon for which this munition is intended.
The projectile is accommodated in a case 4 equipped with a base 5 with a fuse 6, a powder charge 7 and a tamping portion 8.
The dart 1 has a body 11 formed by a succession of sections 11a, 11b, 11c of increasing diameter. These sections are constituted by cylindrical volumes forming shoulders 12a, 12b between them.
