PROBLEM TO BE SOLVED: To provide a propulsion system for the acceleration of projectiles which has low sensitivity to mechanical action, a good "natural discharge" characteristic, and has high capability and potential force simultaneously. SOLUTION: 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 plasticizing additive. The nitramine compound contains a structural element of the general chemical structure formula R-N-NO<SB>2</SB>, where R is a residual group. The nitramine compound is present in a concentration in the range from 1 to 35% by mass, in particular in the range from 5 to 25% by mass. The nitramine compound is preferably RDX. The inert plasticizing 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 plasticizing additive is present in a concentration of 1 to 5% by mass. COPYRIGHT: (C)2008,JPO&INPIT |
