<p>A practice projectile (56...79), for large-calibre guns from 40 mm upwards, is to be equivalent - in trajectory and accuracy - to a combat shell over an initial portion of the trajectory. At the beginning of the second portion of the trajectory, the projectile is to self-destruct in such a manner that none of the parts (2...50) thereof fly beyond the second portion of the trajectory. This is achieved by means of a plurality of pyrotechnical delayed-action fuses (15, 31) which are ignited when the projectile is fired and which, after burning up, ignite gas generators (15, 30). The pressurized gas produced by the gas generators ruptures the connections which hold the projectile together. Individual components of the projectile are separated from each other either by compressed gas and/or by dynamic air-pressure and by the residual spin of the projectile.</p> |
