Abstract

The blade has a metallic core 2 carrying the blade root 2a and a ceramic aerofoil 1 enveloping the core with a resilient substance 4, e.g. ceramic foam or felt, interposed between the core and aerofoil. The core 2 has a head 3 under which one or more shoulders 1e engage to secure the aerofoil 1. The blade may consist of several axial sections 1a, b, c. The core and aerofoil are thus able to expand and contract independently of one another. Cooling air passages 6a may be provided. <IMAGE>
