  • Effusion cooled shroud segment with an abradable system
    Patent number: 9528443
    Abstract: A turbine casing assembly, comprising an annular seal segment assembly for surrounding the turbine adjacent to the turbine blades. An abradable coating is provided on the inboard surface of the seal segments of the assembly and one or more coolant ducts extend from the outboard surface of the seal segment assembly through respective seal segments and the abradable coating, for carrying a coolant towards the blade tips. One or more annular grooves are formed in the inboard surface of the abradable coating, the or each coolant duct opening into one of the one or more annular grooves.

  • Aerofoil cooling arrangement
    Patent number: 9376918
    Abstract: An aerofoil typically for a blade or vane for a gas turbine engine comprises a pressure wall, a suction wall and a web that extends therebetween. One of the walls comprises an inner leaf and an outer leaf which defines a cavity, the other wall defines a first outlet, the aerofoil defines at least one first passage extending from the cavity through the web and to the outlet. Coolant in the cavity on one side wall of the aerofoil is thereby routed across the web to be used to cool the other wall by convention and formation of a coolant film.
