Abstract

A heat shield assembly includes a supporting structure having an outer surface to be shielded from a hot fluid, the supporting structure having cooling fluid ducts formed therein; and an internal lining formed of heat-resistant material, the internal lining including mutually adjacent mushroom-shaped heat shield elements each having a cap portion in the form of a polygonal plate body having a central region, the plate bodies each covering a portion of the outer surface of the supporting structure and defining cooling fluid gaps therebetween, and a shaft portion thermally moveably anchoring the central region of the plate body to the supporting structure.
