1. A thermal radiation shield comprising:
a mounting base configured for securing to an aft mounting surface; and
a corrugated ring section extending axially from the mounting base, the corrugated ring section shaped such that, when the mounting base is secured to the aft mounting surface, the corrugated ring section extends axially forward into a generally annular cavity defined at least in part by a hot fluid flow path boundary wall and a radially adjacent and spaced apart cold fluid flow path boundary wall, the corrugated ring section is suspended via the mounting base and spaced from at least the hot fluid flow path boundary wall;
wherein the corrugated ring section is shaped to substantially block a line of sight from all of the hot fluid flow path boundary wall to the cold fluid flow path boundary wall.
