FIELD: rocketry; liquid propellant rocket engines.
SUBSTANCE: invention relates to method of manufacture of nozzle for combustion chamber of liquid propellant rocket engine. Proposed method of manufacture of welded-soldered large-size nozzle of liquid propellant rocket engine chamber consisting of steel inner and outer envelopes connected with manifold unit includes making of envelopes of sheet blanks using stamping, assembling, welding, slot cutting, application of coating and soldering. Nozzle is made as soldered unit, inner envelope being made solid, seamless, by method of multipass rotary extrusion with subsequent calibration of pack consisting of inner and outer envelopes by explosion with preservation of relative position of envelopes. Girth seam at welding of parts of outer envelope is arranged in zone of welding of under manifold ring.
EFFECT: reduced labor input, metal usage, cost of manufacture and improved reliability of nozzle.
