A disadvantage of propelling charge ignition systems which function according to the induction principle is that unwanted differential gas pressures can occur, especially in the lower temperature range. This can lead to uncontrolled increases in pressure and damage or even destroy the weapon system. Attempts to counteract this with reduced quantities of powder resulted in a significantly poorer performance of the ammunition in terms of the range and penetration power of the projectile, over the entire temperature range. According to the invention, the propelling charge bodies (1) therefore have a cartridge case (2) whose wall (6) supports at least one primary coil (7a, 7b, 7c).
Des différences de pressions gazeuses indésirables peuvent, notamment sur la plage inférieure de températures, apparaître dans les systèmes d'amorçage pour charges propulsives. Elles peuvent entraîner des augmentations de pression incontrôlées et endommager voire détruire le système d'arme. Les tentatives pour empêcher ce phénomène par des réductions de la quantité de poudre ont cependant entraîné, sur l'ensemble de la plage de températures, des pertes de puissance perceptibles de la munition, en ce qui concerne la portée et la force de pénétration des projectiles. Pour résoudre ce problème, il est prévu, selon l'invention, des corps de charge propulsive (1) comportant une douille (2) dont la paroi (6) présente au moins une bobine primaire (7a, 7b, 7c).
