ABSTRACT:
An apparatus for sealing a gap between adjacent rotor blades of a turbine engine rotor assembly and for damping vibrations of the rotor blades is provided. The apparatus comprises a platform seal and a damping block. The damping block is independent of the platform seal and includes apparatus for coupling the platform seal and the damping block. The damping block selectively acts against adjacent rotor blades of the turbine engine rotor assembly, forward of the platform seal, and therefore does not interfere with the platform seal. The coupled damping block and platform seal may be installed in the rotor disc prior to installation of the adjacent rotor blades in the disc, thereby obviating the need to blindly install the platform seal.
