Abstract

L'invention a pour objet une fusée 1 d'impact comportant un corps 2 renfermant un générateur piézoélectrique 4 qui mis en place sur un support solidaire du corps 2 et formant enclume, fusée comportant un piston 7 destiné à venir exercer une contrainte mécanique sur le générateur, piston qui reçoit l'effort d'impact transmis par une coiffe 9. Cette fusée est caractérisée en ce que le piston 7 est monté coulissant par rapport au corps 2 et en ce qu'elle comporte un moyen 10 plastiquement déformable qui est interposé entre la coiffe 9 et le corps 2, moyen qui est déformé par le déplacement de la coiffe 9 lors de l'impact sur une cible, ce déplacement entraînant le déplacement du piston 7.
