Abstract
Abstract A TURBOMACHINE ROTOR INCLUDES BLADE CARRYING RINGS WITH AXIALLY SPACED FLANGES HAVING DOVETAIL SLOTS THROUGH THE FLANGES TO RECEIVE DOVETAIL ROOTS OF EACH BLADE IN THE SLOTS IN EACH FLANGE. A REINFORCEMENT RING OF A FIBER COMPOSITE IS DISPOSED AROUND THE OUTSIDE OF THE RING BETWEEN THE FLANGES. THESE REINFORCEMENT RINGS ARE SPACED SUFFICIENTLY FROM ONE SIDE OF THE FLANGES ABREAST THE SLOTS TO ALLOW MOVEMENT OF THE BLADE TO FREE IT FROM THE SLOTS. FIBER REINFORCED BLADE LOCKING RINGS PREVENTING AXIAL DISPLACEMENT OF THE BLADES ARE MOUNTED ON THE OUTER SURFACE OF THE RING.
