WALL OF LIQUID PROPELLANT SYSTEM CHAMBER Russian patent published in 2023 - IPC F02K9/64 

FIELD: rocket engine building.

SUBSTANCE: manufacture of liquid propellant system chamber (LPS). LPS chamber, containing an outer shell and an inner shell with ribs, through which the shells are mated to each other, according to the invention, cooling channels are made in the outer shell, which are located between the ribs of the inner shell, with the formation of cooling channels of the inner shell. The outer and inner shells are additionally connected to each other by means of radial bridges between the wall of the inner shell and the cooling channels of the outer shell, as well as by means of tangential bridges between the ribs of the inner shell and the cooling channels of the outer shell. In addition, the inner shell is made of a material with a higher thermal conductivity relative to the material of the outer shell.

EFFECT: increase in energy-mass characteristics by removing extremely high heat flows in the combustion chamber, using both fuel components.
