PROCEDE DE FABRICATION DE PAROI DE CHAMBRE DE COMBUSTION, NOTAMMENT POUR MOTEUR-FUSEE, ET CHAMBRE DE COMBUSTION OBTENUE PAR CE PROCEDE.

摘要

The method of manufacturing a combustion chamber wall, in particular for a rocket engine, includes the following steps: [a] making a corrugated metal inner shell by deforming a first plane or tubular sheet; [b] making a metal outer shell from a second plane or tubular sheet; [c] assembling the corrugated inner shell and the outer shell together and welding them together locally; [d] forming an inner coating on the inside face of the corrugated inner shell by the technique of powder metallurgy using a container for the material that is to constitute the inner coating, the outside face of said container being constituted directly by the inside face of said corrugated inner shell and the inside face of said container being made using removable non-consumable sections or a soluble core that is removed by selective chemical dissolving after the inner coating has been formed by applying a hot isostatic compacting cycle; and [e] forming an outer coating on the outside face of the outer shell.
