Abstract:

An assembly for preventing cooling air from leaking from a plenum region formed by a shroud support and a shroud. The shroud support and shroud being so connected as to form a gap which leads from the plenum region to a cavity. The cavity being located in the forward hook region of the shroud support. A rope seal fills the cavity and prevents cooling air from leaking into the cavity causing the cooling air to remain in the plenum region.
