FIELD: machine building.
SUBSTANCE: cermet blade has shaped ceramic shell and drive rod with inner and outer flanges arranged there inside. Said drive rod has flexible pins inclined to drive rod inner flange and staying in contact with inner surface of shaped ceramic shell to ensure stability of said shell and to damp its vibration. Plate spring is arranged between drive rod inner flange and lower thrust flange of said shell to compensate for shaped shell thermal expansion. To up reliability, detachable drive rod outer shell abuts, without clearance, on upper thrust flange of shaped ceramic shell and is secured to rod outer radius.
EFFECT: higher reliability owing to decreased dynamic unbalance and engine vibration.
