Filed:

Jan 9, 2012

Appl. No.:

13/345959

Inventors:

Aaron Gregory Winn - Piedmont SC, US
Niranjan Gokuldas Pai - Clifton Park NY, US
Michael Gordon Sherman - Simpsonville SC, US

Assignee:

GENERAL ELECTRIC COMPANY - Schenectady NY

International Classification:

F04D 29/54
B23P 15/00

US Classification:

415201, 2988802

Abstract:

A turbomachine component includes a body having a first end that extends to a second end. One of the first and second ends includes a mounting element, and a mounting component. A cover plate is arranged at the one of the first and second ends to establish an interface region. The cover plate includes a mounting member configured to align with the mounting element, and a mounting portion configured to align with the mounting element. A fastener member is configured and disposed to cooperate with the mounting element and the mounting member to constrain the cover plate to the body along at least two axes with the interface region being devoid of a metallurgical bond.

Appl. No.:

16/713376

Inventors:

- Schenectady NY, US
Luke C. Sponseller - Greer SC, US
Michael Gordon Sherman - Taylors SC, US

International Classification:

F01D 5/18

Abstract:

A turbine bucket may include a platform, an airfoil extending from the platform at an intersection thereof, and a cooling circuit extending within the platform and the airfoil. The cooling circuit may include a root turn with an asymmetric shape to reduce stress concentrations therein. The asymmetric shape of the root turn may be asymmetrical along a path between a pressure side of the airfoil and a suction side of the airfoil. The asymmetric shape of the root turn may be asymmetrical within a plane defined by a radial direction and a circumferential direction.
