ABSTRACT:
A generator for generating electrical ignition energy through a piezo element in a spin projectile. A guide band on the projectile deforms upon entry into the riflings of a weapon barrel. To generate the ignition energy due to the deformation of the guide band, the piezo element is a tubular member polarized radially relative to the longitudinal axis of the projectile. The outer circumference of the piezo element lies against the projectile shell. The piezo element is stiffened along its inner circumference by a stiffener ring positioned thereagainst.
