The method for producing a propellant powder (TLP) with a layered grain structure starts with a green powder, which is impregnated in a watery emulsion with an energetic plasticizer and a polymeric deterrent. Propellant powders (TLP) can be produced in industrial quantities by avoiding the dangerous direct introduction of a blasting oil. The propellant powders (TLP) produced in this way have similar characteristics and a similar structure as the known propellant powders (TLP).

The propulsion system for the acceleration of projectiles is based on nitrocellulose and contains a crystalline energy carrier on a nitramine base and an inert plasticising additive. The nitramine compound contains a structural element of the general chemical structure formula R—N—NO
2
, where R is a residual.
The nitramine compound is present in a concentration in the range from 1 to 35% by weight, in particular in the range from 5 to 25% by weight. The nitramine compound is preferably RDX. The inert plasticising additive is a water-insoluble polyoxo compound, if necessary in combination with a substance containing carboxyl groups. In layers near the surface an increased concentration can be present. The inert plasticising additive is present in a concentration of 1 to 5% by weight.
