ROTOR ASSEMBLY AND METHOD OF INSTALLING A PLURALITY OF ROTOR BLADES IN A ROTOR ASSEMBLY

A rotor assembly (300) includes a rotor (34) having a dovetail slot (36). The dovetail slot (36) includes a plurality of recesses (44) and a first radially innermost surface (210). A rotor blade (20) includes an airfoil (22) that extends radially outward from a platform (31) and a dovetail (32) that extends radially inward from the platform (31). The dovetail (32) includes a plurality of projections (40) extending in opposite directions that are received by the plurality of recesses (44) of the dovetail slot (36). The second radially innermost surface (46) defines a groove (33) from the leading edge surface (25) to the trailing edge surface (27). The shim (52) is positioned within the groove (33) and between the first radially innermost surface (210) of the dovetail slot (36) and the second radially innermost surface (46) of the dovetail (32). The shim (52) extends at least partially radially along both of the leading edge surface (25) and the trailing edge surface (27) to secure the rotor blade (20) within the dovetail slot (36) during various operating conditions of the turbomachine.
