Abstract

Chargement unitaire de poudre propulsive notamment pour munitions pour armes de petits et moyens calibres. Il est constitué de grains de poudre à la nitrocellulose agglomérés ensemble à l'aide d'un plastifiant gélatinisant de la nitrocellulose, liquide à une température inférieure ou égale à 80 degrés C, et présent en quantité ne dépassant pas 7 % en poids par rapport à la nitrocellulose. Le chargement a pratiquement le potentiel énergétique de la nitrocellulose de départ; de plus il se fragmente et brûle instantanément comme une poudre en vrac.
