HEAT SHIELDING STRUCTURE

摘要

The invention concerns a heat shielding structure (1) characterised in that it comprises means (4A) for cooling by ejection, ejecting a first cooling fluid outside said structure (1) and/or a heat barrier (2) forming at least part of said structure (1) outer wall, said heat barrier (2) being perforated so as to enable a first cooling fluid to be ejected, and/or means (4B) for cooling by convection, comprising a second cooling fluid circulating inside the structure (1) relative to the heat barrier (2), said first and second cooling fluids being derived from a common fluid.
