Composite ceramic gas turbine blade

摘要

A gas turbine blade constituted of a supportive metallic blade core and a thin-walled ceramic blade airfoil, in which the airfoil is supported against a tip plate of the blade core. The blade core consists of rod or wire-shaped pins which have widened bases at their radially inner ends. Through these widened bases, the pins are retained in a metallic adapter slidable into a turbine disc.
