Fuse with a piercing head for a projectile

摘要

The projectile fuse comprises a piezoelectric generator located forward of a piercing part (2) and formed by a striker (5), a hammer (6) and a crystal (8). The firing device comprises a watch movement (11) providing a muzzle safety and making possible the positioning of a rotary support (15) for at least one primer (24). A part (2) of material with high mechanical resistance acts as the piercing head for the projectile after the dislodging of the electric generator at the moment of impact and effectively protects the watch movement (11) and the rotary support (15).
