ABSTRACT:
An annular turbine blade tip shroud is provided having a construction for minimizing leakage of the cooling fluid and preventing ingestion of hot gases into said cooling flow. A tip shroud support ring is located on the inner surface of said casing with tip shroud members affixed thereto and encasing the blade tips. An annular metal can is located over the forward ends of said tip shroud members and has a sealing engagement with the tip shroud support ring. This annular metal can also seals with feather seals located between adjacent ends of cooperating tip shroud members. A positive metal bellows seal is also provided between downstream vanes and the outer casing. A sheet metal seal is located between each tip shroud member and tip shroud support ring to aid in maintaining proper cooling flow through the shroud.
