摘要:
Provided are a method of forming a rotating component. The method for forming a rotating component includes providing a rotor (101) having an outer surface. A circumferential surface feature (131) is formed on the outer surface of the rotor (101). The forming includes applying metallic material to the outer surface of the rotor (101) to build up the circumferential surface feature (131) on outer surface of the rotor (101) to define at least one cooling passageway (211). A rotating component having a circumferential surface feature (131), a turbine system and an apparatus for forming the rotating component are also disclosed.

摘要:
A turbomachine blade may include an airfoil (122) and a shank (124) coupled to the airfoil. The shank may include a cover plate (132) having a first circumferential face and a second, opposing circumferential face. A radial cooling groove (250) is positioned in the first circumferential face and is configured to allow a cooling fluid to pass from a first radial position to a second, different radial position relative to the platform. The radial cooling groove (250) provides cover plate and shank cooling. In addition, the radial cooling groove may deliver fluid for purging gaps between blade platforms and cover plates, which prevents the ingestion of hot gas from the turbine flowpath.
