摘要： A turbine includes a turbine seal. The turbine seal includes a first straight portion extending along a first axis. The turbine seal also includes a second straight portion extending along the first axis. The first and second straight portions of the turbine seal intersect to form a V-shaped cross section with an opening extending along the first axis. The first and second straight portions of the turbine seal are also configured to resiliantly move towards and away from each other and the first and second straight portions of the turbine seal are configured to pre-load the turbine seal along a gap between first and second bucket segments of the turbine.

摘要： A method for assembling a rotor assembly for gas turbine engine is provided. The method includes providing a first rotor blade that includes an airfoil, a platform, a shank, and a dovetail. The airfoil extends radially outward from the platform, the shank extends radially inward from the platform, and the dovetail extends from the shank, forming a recess within a portion of the shank. The method also includes coupling the first rotor blade to a rotor shaft using the dovetail, and coupling a second rotor blade to the rotor shaft such that a shank cavity is defined between the first and second rotor blade shanks. During operation, cooling air may enter and pressurize the shank cavity through the recessed portion.

摘要： A turbine has blade assemblies disposed about a rotor. Each of the blade assemblies have an airfoil and a bucket. Pockets are defined at trailing and leading sides of the bucket, with damper pin slots at an ends thereof. The damper pin slot at the trailing side has a depth sufficient for fully receiving a damper pin. The damper pin slot at the trailing side of a first adjacent blade assembly is positioned relative to the damper pin slot at the leading side of a second adjacent blade assembly to allow the damper pin to move. At each side of the pocket at the trailing side is a seal pin slot with seal pins therein. The seal pin slots extend beyond a line that is aligned with an inner edge of the damper pin slot at the trailing side, wherein the seal pins overlap the damper pin.
