Enclosure containing hot gases cooled by transpiration, in particular the thrust chamber of a rocket engine

摘要: An enclosure containing hot gases cooled by transpiration includes means for applying a cooling fluid, said comprising hydraulic calibration sheath applied on the outside face of porous wall that forms inside portion enclosure, being made material is proof to liquid and perforated multiplicity microperforations having distribution density varies progressively over various different portions so as provide greater perforation wherever heat flow be reaching high, fluid feed volume formed between secured an outer sealing envelope apply pre-determined rate per unit area in zones spacers interposed envelope.
