Method of manufacture of an enclosure containing hot gases cooled by transportation, in particular the thrust chamber of a rocket engine

摘要

A method of manufacturing an enclosure containing hot gases cooled by transpiration comprises:PPforming a shaped rigid shell comprised of a microperforated sheet metal, hydraulic calibration sheath, PPwelding spacers to an outside face of the hydraulic calibration sheath;PPwelding an outer sealing envelope on an outside surface of the spacers and the partitions; andP Pforming a porous wall by applying a deposit onto an inside face of the hydraulic calibration sheath.
