METHOD TO MANUFACTURE A CHARGE OF MIXED SOLID PROPELLANT FOR ROCKETS Russian patent published in 2003 - IPC

FIELD: chemical industry. SUBSTANCE: The invention presents a method to manufacture a charge of mixed solid propellant for rockets (MSPR) According to the invention, the method of manufacture of a MSPR charge includes a proportioning of MSPR components in the mixer of a premixing of the mixing machine, following mixing of doses of MSPR components for obtaining composite fuel in series first in the mixer for premixing in the upper and lower mixers of the mixing machine, feeding of the propellant mixture from the lower mixer to formation of the charge by pressure die casting, at that they execute the check of a ratio of the fed doses of MSPR components and in the case of distortion of the fed doses of MSPR components ratio before the expiration of the time of their residence in the upper mixer terminate the proportioning of MSPR components from the moment of the distortion and submission of composite fuel from the upper mixer in the lower mixer and from the lower mixer - to forming of the a charge, admix composite fuel in the upper mixer and make proportioning of the necessary amount of doses of MSPR components for obtaining required components ratio in the upper mixer. Then after proportioning of 4-9 complete doses of MSPR components, terminate the metering-in, once more agitate propellant mixture in the upper mixer and then renew a proportioning of MSPR components in the mixer of premixing. EFFECT: invention presents a method of manufacture of MSPR charge in the case of distortion of ratio of the MSPR components proportioning fed in the mixer. 1 dwg, 1 tbl
