Abstract

An electrical projectile detonator, particularly a base detonator, containing a piezoceramic cell as a current generator. The cell is retained against the inside of the projectile base or base screw. A rupture plate is positioned on the outside of the base at a predetermined spacing from the cell. The rupture plate is adapted to be disintegrated by the gas pressure of the projectile propellent charge to thereby produce a shock wave in the projectile base. This shock wave propagates within the projectile and loads the piezoceramic cell so as to generate a voltage in the cell.
