PREPARATION OF VULCANISING EQUIPMENT FOR OPERATION

摘要

FIELD: engines and pumps.SUBSTANCE: invention relates to fabrication of internal heat protective coating of rocket engine bodies from composites, that includes the preparation of vulcanisation equipment. Here, at preparation of this equipment for operation after installation of vacuum bag compressed air is forced in the cavity between mandrel with composite and vacuum bag for inflation of vacuum bag and its levelling. Then, overpressure is released to evacuate said cavity between mandrel with composite and vacuum bag and to force liquid fluid in cavity between vacuum bag and cover of hydrostat.EFFECT: simplified application of this process, higher quality and lower labour input.2 dwg, 1 ex
