Abstract
A method of manufacturing an enclosure containing hot gases cooled by transpiration comprises: PA1 forming a shaped rigid shell comprised of a microperforated sheet metal, hydraulic calibration sheath, PA1 welding spacers to an outside face of the hydraulic calibration sheath; PA1 welding an outer sealing envelope on an outside surface of the spacers and the partitions; and PA1 forming a porous wall by applying a deposit onto an inside face of the hydraulic calibration sheath.
