MOLDING PROCESS FOR MAKING A DOUBLE BASE PROPERGOL BLOCK WITH A HIGH RATE OF NITRAMINE AND PROPERGOL BLOCK OBTAINED BY THIS PROCESS

摘要

The subject of the invention is a new process for producing a double-base propellant block with a high nitramine content, having a high combustion rate and a great regularity of combustion over a very wide range of pressure. This process consists of casting a molding solvent consisting of a nitric ester, a plasticizer, a stabilizer on a molding powder placed in a mold and formed from nitrocellulose with a nitrogen content between 11 , 5 and 13%, a nitric ester, stabilizers, at least one nitramine, combustion catalysts or plasticizers, to cook all and is characterized in that the level of nitric ester and nitramine in percentage by weight in the molding powder is respectively between 5 and 30% on the one hand and 35 and 60% on the other hand and in that the combustion catalysts consist of a catalytic system based on copper salts, lead and acetylene black or benzene. / P
