Patent ID: 7520718

Claim:
A plate positionable between adjacent turbine blades, comprising: a generally curved body that is curved circumferentially about a longitudinal axis of a turbine rotor assembly and having an engaging surface for contacting a root of a turbine blade to position the turbine blade axially within the turbine rotor assembly and seal the turbine blade; a connector tor attaching the generally curved body to the turbine rotor assembly that is configured to separate longitudinal adjacent turbine blades; wherein the connector is configured to be attached to a mini disk separating longitudinally adjacent turbine blades; and an extension arm extending from the generally curved body for limiting flow of cooling fluids between the turbine blade and an adjacent turbine vane; wherein the generally curved body comprises a first section to which the connector is attached, a second section extending at an acute angle from the first section and opposite to the connector, and a third section extending from the second section and aligned with the first section, wherein the engaging surface is attached to the third section.
