FIELD: liquid-propellant rocket engines.
SUBSTANCE: proposed nozzle is made in form of solid or revolution with diameter of cross-section changing along its longitudinal axis 11. Nozzle has wall with great number of cooling channels arranged close to each other in spiral practically in parallel to each other, passing along entire length of nozzle from its inlet end 13 to outlet end 14. Nozzle consists of at least two sections 10a, 10b, 10c arranged along axis. In place of butt joining of adjacent sections, angle of tilting of cooling channel arranged along spiral to longitudinal axis of nozzle changes its sign from plus to minus, which makes it possible to balance reaction rolling moments appearing in nozzle owing to friction between exhaust gases and nozzle wall. Method of manufacture is described.
EFFECT: provision of balancing of reaction rolling moments.
