Abstract

A spin stabilized payload projectile 10, in order to separate a projectile base connected with projectile body 11 and to eject a payload 13, is provided with an ejection charge 15 in its nose region, with such ejection charge being activated with a certain delay by a nose fuze 14. To prevent damage to the nose fuze 14 by the gas pressure generated by ejection charge 15, a pressure reducing element 20 is disposed between nose fuze 14 and the ejection charge. In a particularly advantageous embodiment of the invention, this pressure reducing element 20 is composed of a cone or a cone frustum whose base face faces nose fuze 14 and whose tip faces ejection charge 15. The tip of pressure reducing element 20 is provided with an opening 20a through which a firing jet travels from nose fuze 14 to ejection charge 15 for the purpose of activating charge 15. After activation of ejection charge 15, pressure reducing element 20 is deformed into a substantially gas tight disc.
