Propulsion system (I) for the acceleration of projectiles that is based on nitrocellulose, comprises a crystalline energy carrier on a nitramine base and one or many inert plasticizing additives, where at least one of the inert plasticizing additives is present, essentially homogeneously distributed, in a matrix of (I), and the one and/or another inert plasticizing additive has an increased concentration in zones near the surface. An independent claim is included for the preparation of (I), manufacturing a powder cake containing solvent, on the base of nitrocellulose and crystalline energy carrier on a nitramine base, and one or many inert plasticizing additives; extruding the powder cake containing a green grain solvent; surface treating with an inert plasticizing additive, so that the inert plasticizing additive in the zones near the surface has a weight proportion of not more than 10 wt.%. particularly less than 6 wt.%. |
