Practice cartridges for artillery shooting are known, which reduce the practical training in a Allow a scale of about 10: 1 in relation to the actual conditions. These Practice cartridges, which have a caliber of approximately 14 to 20 mm, have a percussion fuse and a smoke generator of usual composition. In these storeys, however, only a relatively small amount can be used Smoke generator can be accommodated. Elapsed from the impact to the ignition of the smoke generator a certain time, so that the projectile in unfavorable terrain, z. B. loose sandy soil, already some depth below the ground before the smoke generator can take action. He can therefore be completely swallowed up by the soil above.

It has now been shown that despite the small amount of smoke, one can also work well at greater distances Visible marking of the impacts can be achieved by opening the smoke generator sleeve in which the smoke generator is located is thrown out of the projectile after the impact ignition. To this end, it is proposed the smoke generator sleeve housed a primer that contains a propellant. The primer is open the side facing the igniter an opening through which the flame of the igniter can strike. On the on the other hand, the primer cap has an opening with a larger diameter than the opening of the smoke generator sleeve. The primer thus transmits the igniter's pilot flame with practically no delay on the smoke generator and expels the entire smoke generator sleeve with the smoke generator from the floor.

An embodiment is shown in the drawing. In the front part of the projectile 1 is the igniter 2 with the primer 3. The ignition flame of the primer 3 strikes the primer 5 with propellant 6 through the hole 4 in the projectile. The primer 5 has an opening on the side facing the smoke generator sleeve 7 9, exercise cartridge

which has a larger diameter than the opening 10 of the smoke generator sleeve 7. The flame of the propellant charge 6 strikes on the one hand through the opening 10 of the smoke generator sleeve 7 into the smoke generator 8 in order to ignite it. On the other hand, the deflagration gases of the primer 5 simultaneously expel the smoke generator casing 7 with the smoke generator 8 from the projectile body 1 .

Claims (1)

Claim: Exercise cartridges up to 20 mm caliber with a pyrotechnic smoke signal charge, characterized in that a primer (5) with propellant charge (6) is located between the igniter (2) and the smoke unit charge (8) , which ejects the smoke unit casing (7) from the projectile (1) and at the same time ignites the smoke generator so that it burns down outside the projectile body.
