    摘要: A stator assembly (22) for a gas turbine comprising is provided with:
    • a stator ring (24), which extends about a longitudinal axis (A) and comprises an inner edge and an outer edge (29); the outer edge being provided with an annular groove (30); the annular groove (30) defining a leading wall (34) and a trailing wall (35); the trailing wall (34) being provided with an annular trailing radial face (36a) and with an annular trailing axial face (36b);
    • a plurality of stator vanes (25) radially arranged and coupled alongside one another to the outer edge (29) of the stator ring (24) so as to close the annular grove (30) and define an annular cooling channel (32);
    the stator ring (24) being provided with at least one trailing cooling hole (39) having an inlet (40) facing the annular cooling channel (32) and an outlet (41) arranged on the annular trailing radial face (36b).

    摘要: A seal assembly for a gas turbine comprises at least one main spring configured to be at least partially housed in a seat (19) of a combustor outlet member (17), at least one flexible seal member having a plate portion disposed on an outer side of the main spring and having an outer blade configured to sealingly cooperate with a seat surface, and at least one shield seal member having a plate portion disposed on an outer side of the plate portion of the flexible seal element and a flange configured to contact axially a vane surface under the axial elastic load of the main spring. A corresponding gas turbine comprises an outer casing, a compressor, a plurality of can combustors (10) downstream of the compressor and a turbine downstream of the can combustors (10), the compressor and turbine comprising fixed vanes (14) carried by the outer casing and rotating blades carried by a rotor. The can combustors are spaced around the rotor and produce hot gas by combusting a mixture of air and at least one fuel. The gas turbine includes, for each can combustor, a seal assembly axially interposed between an outlet member (17) of the combustor (10) and at least one turbine vane and radially interposed between an outer hot gas path (12) and an inner space containing higher-pressure cooling air.

    摘要: A blade or vane for a compressor comprises a main body (15; 25) provided with a base face (16; 26), with a top face (17; 27), opposite with respect to the base face (16; 26), and with an outer face (18; 28), which extends between the base face (16; 26) and the top face (17; 27) and defines the airfoil profile of the blade or vane (7; 10; 70; 700); the main body (15; 25) being shaped so as to define along the outer face (18; 28) a leading edge (30), a trailing edge (31), a pressure side (32) and a suction side (33); and at least one appendix (29; 79; 779) arranged in the proximity of the trailing edge (31).
