Method of manufacture of propellant charges of propellants a double - base by welding a hot

摘要

P manufacture of propellant charges of double-base propellants for meeting of the constituent elements of the said charges. / p & & p & method comprising: a) placing, in a mould comprising a cavity of welding with a part of the outer profile of the propellant charge to be obtained, of the said constituent elements of the juxtaposed to each other by the surfaces to be joined together; b) the sealed closure of the mold, the welding temperature and the vacuum in the cavity of the welding; c) the displacement of a punch, with the geometrical profile complementary to the propellant charge to obtain, in the cavity of welding in order to compress said constituent elements against each other so as to be welded at the level of the faces in contact; d) the cooling of the mold and the removal of the propellant charge is heat-sealed. / p & & p & the combustion of the propellant charges thus produced has no disturbance when the flame front reaches the interface of the constituent elements of these charges. / p
