Abstract
The invention relates to a process for the manufacture of a double-base propellent composition with low flame-glare emission, and a propellent composition thus obtained. The process of the invention consists in casting a nitrocellulose-based moulding powder with a nitroglycerine-based casting solvent. According to the invention, the moulding powder consists of a mixture of two powders, one of which contains the antiglare agents, and the weight ratio of the powder containing the antiglare agents to the other powder is between 15/85 and 50/50. The invention permits an antiglare agent to be added to a propellent composition without affecting the ballistic properties of the composition, while strengthening the antiglare effect of this agent. The invention is applicable particularly in the field of solid-fuel propulsion.
