METHOD OF PROTECTION OF INNER SURFACE OF ROCKET ENGINE HOUSING Russian patent published in 1998 - IPC

Abstract RU 2117811 C1

FIELD: manufacture of rocket engines; rocket projectile engines of salvo fire system working on solid composite propellant; lining of inner surfaces of cylindrical articles working in stressed mechanical, temperature and chemical media. SUBSTANCE: includes heating of housing, application of composition on base of low-molecular rubber on its inner surface by rotating the housing followed by hardening of composition. Composition is used at starting viscosity of η+20oC = 3100...3400 poises on base of polyvinyl epoxy urethane rubber with fillers and hardeners. Heating is continued to 60-100 C. Housing is rotated at a rate of 800 to 1300 r/min at a temperature of 80 to 120 C for 10 to 35 minutes. Hardening is effected at a temperature of 115 to 135 C for 3 to 8 hours at a pressure ranging from 1.2 to 1.4 kgf/sq. cm. EFFECT: enhanced reliability of protection. 1 tbl
