Abstract

An impact detonator for a projectile, for detonating a material after impacting an obstruction, comprises a detonation chain composed of a pyrotechnic mass (3) and a pyrotechnic detonation agent (4, 5, 6). The pyrotechnic mass and the agent can move relative to each other. They are separated before impact and move towards each other on impact of the projectile (1).
