Abstract
A rotor assembly for use with a turbine engine. The rotor assembly includes at least one rotor disk that includes an inner surface that defines a dovetail groove. At least one turbine bucket is coupled to the rotor disk. The turbine bucket includes an airfoil that extends outwardly from a dovetail. The dovetail is inserted at least partially within the dovetail groove. A tang assembly extends from one of the inner surface of the rotor disk and the dovetail. the tang assembly minimizes a rotation of the turbine bucket with respect to the rotor disk.
Claims20
A rotor assembly for use with a turbine engine, said rotor assembly comprising:
- at least one rotor disk comprising an inner surface defining a dovetail groove;
- at least one turbine bucket coupled to said rotor disk, said turbine bucket comprising an airfoil extending outwardly from a dovetail, said dovetail inserted at least partially within said dovetail groove;
- and
- a tang assembly extending from one of said inner surface of said rotor disk and said dovetail, said tang assembly minimizes a rotation of said turbine bucket with respect to said rotor disk.
A turbine engine comprising:
- a generator;
- a turbine coupled to said generator;
- and
- a rotor assembly extending through said turbine, said rotor assembly comprising:
- at least one rotor disk comprising an inner surface defining a dovetail groove;
- at least one turbine bucket coupled to said rotor disk, said turbine bucket comprising an airfoil extending outwardly from a dovetail, said dovetail inserted at least partially within said dovetail groove;
- and
- a tang assembly extending from one of said inner surface of said rotor disk and said dovetail, said tang assembly minimizes a rotation of said turbine bucket with respect to said rotor disk.
A method for assembling a rotor assembly for use with a turbine engine, said method comprising:
- providing at least one rotor disk that includes a dovetail groove defined by an inner surface, a first axial surface, and a second axial surface, the inner surface extending generally axially between the first axial surface and the second axial surface;
- defining a tang assembly within the dovetail groove, the tang assembly extending from one of the inner surface, the first axial surface, and the second axial surface;
- and
- providing a turbine bucket including an airfoil and a dovetail;
- coupling the turbine bucket to the rotor disk such that the tang assembly is between the turbine bucket and the rotor disk to minimize rotation of the turbine bucket with respect to the rotor disk.
