Turbine cover-seal assembly
This patent describes a gas turbine power plant having a turbine rotor comprising a turbine disk circumferentially supporting radially extending turbine blades, each of the blades having a root section fitting into a recess formed on the rim of the turbine disk. Cover means fit adjacent the face of the disk at the juncture of the root section to overlie the recess and form a sealing means to prevent windage. Each of the cover means include an axially extending portion extending axially into the recess adjacent but spaced from the rim of the disk defining a gap for retaining cooler air migrating from the cooler portion of the turbine rotor for encapsulating cooler air so as to define an insulation barrier against the gas path of the power plant.
