FIELD: process engineering.
SUBSTANCE: invention relates to machine building and may be used for production of liquid-propellant rocket engine chamber nozzles. Proposed method comprises performing shell stack, annealing and blast sizing. Prior to blast sizing, two steel rings are mounted on annealed shell stack in hot state. Said stack is allowed in said state unless complete cooling.
EFFECT: optimum clearance, power savings.
