Ceramic blade

Abstract

Abstract PURPOSE:To aim at improvement in the anti-vibration strength of a blade by providing an auxiliary member to contact with the ceramic made blade. CONSTITUTION:A plate 5 made of ceramic identical to or different from the ceramic of a blade 3 is arranged along the side of the ceramic made blade 3. The plate 5 is wound around the whole lower side of a root 4 and the root 4 is embedded in a disk 2 integrally with the plate 5. Even though the blade 3 is elastically vibrated, very little friction is generated at a contact portion between the blade 3 and the plate 5 and structural damping is produced. The anti-vibration strength of the plate can be thereby improved.
