Abstract (en)
[origin: EP1878995A2] The rocket impact (1) comprises a body (2) having a piezoelectric generator (4) placed on a support of the body, which forms an anvil, and a piston (7) to exert a mechanical constraint on the generator and to receive an effort transmitted by a cap. The piston slides with respect to the body. A plastic deformable unit is interposed between the cap and the body, where the unit is distorted by a movement of the body during the impact of the rocket on a target. An energy consumed by the distortion of the unit ensures a progressive pressing of the piezoelectric generator. The rocket impact (1), comprises a body (2) having a piezoelectric generator (4) placed on a support of the body, which forms an anvil, and a piston (7) to exert a mechanical constraint on the generator and to receive an effort transmitted by a cap. The piston slides with respect to the body. A plastic deformable unit is interposed between the cap and the body, where the unit is distorted by a movement of the body during the impact of the rocket on a target. An energy consumed by the distortion of the unit ensures a gradual collapse of the piezoelectric generator during the impact of rocket on the target. The plastic deformable unit is constituted by a metal washer (10). The metal washer has two deformable caps separated by a groove.
