Abstract

A component for a gas turbine engine (20) includes an airfoil shell (92; 192) having an internal cavity (84) and extending between a radially inner platform (70) and a radially outer platform (72). The component also includes a spar (86; 186) disposed within the internal cavity (84). The airfoil shell (92; 192) has a greater resistance to heat than the spar (86; 186), and the spar (86; 186) has a greater strength than the airfoil shell (92; 192). A radiant heat shield (90; 190; 290; 390) circumscribes the spar (86; 186) within the internal cavity (84). The radiant heat shield (90; 190; 290; 390) is enclosed within the airfoil shell (92; 192) and has a reflectance to radiant heat that is greater than or equal to that of the spar (86; 186).
