Abstract
A turbine blade is disclosed. The turbine blade may have an airfoil extending from a first surface of a turbine platform. The turbine blade may further have a first side pocket of the turbine platform that is configured to substantially entirely house a first moveable seal between a forward wall of the first side pocket and an aft wall of the first side pocket. The first side pocket may have a convex surface, extending between the forward wall and the aft wall, and a concave surface. The turbine blade may also have a second side pocket of the turbine platform configured to receive a portion of a second moveable seal.
Claims23
A turbine blade, comprising:
- an airfoil extending from a first surface of a turbine platform;
- a first side pocket of the turbine platform configured to substantially entirely house a first moveable seal between a forward wall of the first side pocket and an aft wall of the first side pocket, wherein the first side pocket includes a convex surface, extending between the forward wall and the aft wall, and a concave surface;
- and
- a second side pocket of the turbine platform configured to receive a portion of a second moveable seal.
A method of assembling a turbine rotor assembly, the method comprising:
- mounting a first turbine blade to a turbine rotor;
- positioning a moveable seal substantially entirely within a side pocket of the first turbine blade;
- and
- after mounting the first turbine blade to the turbine rotor and after positioning the moveable seal substantially entirely within the side pocket, slidably mounting a second turbine blade to the turbine rotor in a direction substantially parallel to the rotational axis of the turbine rotor past the moveable seal.
A turbine rotor assembly, comprising:
- a turbine rotor including a first slot and a second slot;
- a first turbine blade mounted within the first slot and including a pressure side pocket on a pressure side of the first turbine blade, the pressure side pocket including a concave surface and convex surface;
- a second turbine blade mounted within the second slot and including a suction side pocket mounted on a suction side of the second turbine blade;
- and
- a moveable seal configured to move between a first position where the moveable seal is disposed entirely outside of the suction side pocket and a second position where the moveable seal is disposed partially within the suction side pocket.
A method of regulating the flow of gases past a turbine rotor, comprising:
- rotating the turbine rotor;
- guiding a moveable seal from a first position, housed substantially entirely within a first turbine blade, along a concave surface of the first turbine blade and a convex surface of the first turbine blade into a second position, wherein the moveable seal is wedged between the first turbine blade and a second turbine blade.
