Abstract: A device for generating impacts on a structure has a projectile head. The head includes a main body on which an impact element is mounted so it projects. The device includes a mechanical propulsion element to set the projectile head in motion, and the propulsion element can move between an initial resting position where the propulsion element is immobile and the projectile head is held against the propulsion element by at least one retaining element, and a second position where after the propulsion element comes to a stop against stop elements, the projectile head moves alone in translation toward the structure guided by guidance elements. The device also includes an anti-rebound system to prevent any rebound by the projectile head after impact on the structure.

Abstract: The invention concerns a device for generating impacts on a structure, and this device has a projectile head. According to the invention, this head includes a main body (1) on which an impact element (2) is mounted so it projects. The device includes a mechanical propulsion element (8) to set this projectile head in motion, and the propulsion element is capable of moving between an initial so-called resting position where that propulsion element is immobile and the projectile head is held against it by at least one retaining element (10), and a second position where this propulsion element comes to a stop against stop elements (11, 12), and the projectile head moves in translation toward the structure guided by guidance elements (4). The device also includes an anti-rebound system (6, 7) to prevent any rebound by the projectile head after impact on the structure.
