A turbine blade damper-seal assembly includes a seal nested within a damper such that both the seal and damper are disposed to provide sealing between adjacent blade platforms. The seal traverses the seal slot in the damper and seals the gap between adjacent blade platforms for the full axial length of the neck cavity between adjacent blades. The damper is located in an aft most position and includes features to facilitate vibration-dampening performance. The damper also includes features that cause entrapment between blades and therefore avoids the conventionally required protrusions on the blade to retain it in the assembled position.

What is claimed is: 1. A gas turbine engine rotor assembly comprising:a multitude of blades spaced apart from each other for rotation about an axis of rotation, each of said plurality of turbine blades having a blade platform which defines an inner platform surface and an outer platform surface;a damper having a lengthwise seal slot and an aft seal surface adjacent said inner platform surface, said damper includes a damper body with a forward leg which extends from said damper body transverse to said lengthwise seal slot and an aft leg which extends from said damper body transverse to said lengthwise seal slot and generally parallel to said forward leg, said aft leg having an aft seal surface; anda seal nested with said lengthwise seal slot and disposed adjacent said inner platform surface.
