Patent ID: 8661641

Claim:
A rotor blade assembly tool for coupling a plurality of circumferentially spaced rotor blades to a rotor disc of a turbine rotor, wherein each rotor blade extends from the rotor disc to a radially outer blade tip and includes a platform extending from the rotor blade in opposed circumferential directions, a plurality of components are each disposed radially between the respective platforms of the rotor blades and the disc, and circumferentially between adjacent said rotor blades, the tool comprising: a base ring; and an array of circumferentially spaced resilient fingers supported on the base ring, the fingers extending in a substantially axial direction and being configured to radially abut the components against a radially inner facing surface of the platforms, respectively, when the rotor blades are installed on the rotor disc, each of the fingers having a maximum thickness in a radial direction with respect to the rotor blade assembly, smaller than a radial clearance between the disc and a land of the respective platforms.
