FIELD: blasting operations.SUBSTANCE: invention relates to methods of production of large-sized charges of mixed solid rocket fuel (MSRF) by method of free casting. The method of manufacturing a MSRF charge comprises placing the mounted with channel-forming fitments and the drainage pipe line of the housing in the altitude chamber, coupling of the drainage pipe line with the drain valve of the mixer, vacuumising of the altitude chamber and the housing and draining the fuel mass into the housing, at that for placing the housing in the altitude chamber the altitude chamber lid is removed, the drainage pipe line is mounted on it, on which from the inner side of the lid the housing is mounted assembled with the channel-forming needle, and mounted into the altitude chamber housing.EFFECT: possibility of manufacturing the MSRF charge in thin-walled housing of free casting without mounting the housing in the altitude chamber on the stand.1 dwg |
