FIELD: rocket technics.
SUBSTANCE: invention relates to rocket technology, namely to a method for manufacturing a nozzle of a liquid rocket engine chamber. Nozzle of the liquid rocket engine chamber including the inner and outer shells, interconnected by fins forming the cooling channels, a subcollective ring with holes that are connected to the cooling channels, and the collector, according to the invention the nozzle of the chamber is a single integral structure, manufactured by the method of layer-by-layer powder laser sintering of granules. Collector can be made of a non-circular shape, of variable cross-section, and the openings connecting the collector with the cooling path have a section of non-circular shape, are a continuation of the cooling path and are not overlapped by the fins.
EFFECT: invention provides a reduction in labor intensity and rigidity in the manufacture of the nozzle.
