FIELD: rocket engines.
SUBSTANCE: invention relates to chambers of liquid propellant rocket engines (LPRE). LPRE chamber operating at high pressures, containing a supersonic part of the nozzle with cooling channels, underwater and outlet lines, while the cooling channels with ribs are made with a varying angle of rotation from the longitudinal axis of the chamber to the transition point to an increased number of channels and ribs, which is determined by the thickness of the ribs and the size of the channels according to the dependence
where δribs - thickness of the rib; δchannel - channel thickness; n - the number of ribs; α - angle of inclination of the ribs of part 2; D - variable diameter of the profile of the nozzle part, and to ensure equalization of the coolant flow in the ribs, selections are made, interconnected by channels in the annular rib.
EFFECT: invention provides improvement of energy-mass characteristics.
