COMPONENT OF ROCKET ENGINE AND METHOD FOR MANUFACTURE OF ROCKET ENGINE COMPONENT Russian patent published in 2006 - IPC F02K9/64 

FIELD: liquid-propellant rocket engines.

SUBSTANCE: the component has a load-wall bearing with cooling ducts, whose outer surface is formed by a shell of sheet metal fastened to which in the longitudinal direction are cooling ducts, the load-bearing wall is coated by a layer of material applied on the shell. The layer features a high thermal conductivity, it forms a continuous contact surface running on the shell from the wall of one cooling duct to the wall of the cooling duct adjacent to it, and which partially envelops the walls of the cooling ducts. The method for manufacture of the component is considered.

EFFECT: reduced thermal load on the bearing wall.
