A turbine vane and a gas turbine including the same are provided. The turbine vane includes an airfoil having a pressure side and a suction side, at least one cooling channel formed radially in the airfoil, and an insert inserted into the at least one cooling channel to divide the cooling channel into a pressure side passage and a suction side passage.

The present disclosure is directed to a shroud assembly for a gas turbine engine that includes a first shroud segment, a second shroud segment spaced from the first shroud segment, and a third shroud segment spaced from the first shroud segment. The first and the second shroud segments define a gap therebetween, and the first and the third shroud segments define a gap therebetween. A first seal portion is positioned at least partially on the first and the third shroud segments and at least partially covers the gap defined by the first and the third shroud segments. A second seal portion is positioned at least partially on the first and the second shroud segments and at least partially covers the gap defined by the first and the second shroud segments. A third seal portion extends between and couples the first and the second seal portions.

The present invention relates to a stator vane adjusting device of a gas turbine having a plurality of stator vanes each swivellable about a radial axis and arranged in at least two radial planes, as well as at least two stator vane adjusting rings connected to the respective stator vanes and rotatable in the circumferential direction by at least one actuating device, characterized in that the actuating device is connected to the stator vane adjusting rings by means of a first transmission device and that a second transmission device, which is not coupled to the actuating device, is arranged essentially opposite to the first transmission device, with the second transmission device being connected to the stator vane adjusting rings.

A washer includes a first lobe comprising a first hole, a second lobe comprising a second hole, a third lobe comprising a third hole, and a fourth lobe comprising a fourth hole. A first leg extends from the first lobe to the second lobe, and a second leg extends between the third lobe and the fourth lobe, wherein the second leg is parallel to the first leg. A third leg extends from the first lobe to the third lobe and spaces the first leg from the second leg such that the second lobe is disposed opposite the fourth lobe.

A vane arc segment includes an airfoil fairing that has first and second platforms and an airfoil section. The platforms have first and second openings that open into the airfoil section. The platforms each define first and second circumferential mate faces, forward and aft sides, a gaspath side, a non-gaspath side. The first platform has a first flange that projects radially from the non-gaspath side aft of the first opening and a second flange that projects radially from the non-gaspath side forward of the first opening. The first and second flanges are exclusive flanges on the first platform. The second platform has a third flange that projects radially from the non-gaspath side aft of the second opening.

A turbomachine includes: a stator-side housing having: a plurality of stator-side guide vane supports fastened to the stator-side housing, stator-side guide vanes fastened to the stator-side guide vane supports, and axially spaced guide vane rings; and a rotor having a plurality of rotor-side moving blades. At least two guide vane supports are jointly fastened to and centered on a flange of the stator-side housing.

A hydraulic rotary actuator including a stator housing having a through bore to position a rotor assembly. A rotor assembly includes an output shaft and at least a first rotary piston member disposed radially about the output shaft. The rotary piston member includes an vane element. A continuous seal is disposed on peripheral longitudinal faces and lateral end faces of the rotary piston element. The bore through the stator housing includes an interior cavity with surfaces adapted to receive the rotor assembly and contact the continuous seal. With rotation fluid ports blocked, the housing cavity is sealed with the continuous piston seal for hydraulic blocking, preventing actuator displacement by external forces. A method of operation and method of assembly is disclosed.
