Abstract
A blade attachment apparatus for a turbine is provided and includes a member, which rotates about an axis of the turbine, including fore and aft disk posts that retain corresponding fore and aft turbine blades, respectively, fore and aft of a turbine nozzle and a central portion proximate the turbine nozzle and an attachment retained between the fore and aft disk posts and the fore and aft turbine blades and coupled to the central portion, such that a portion of the attachment interrupts a purge flow through the turbine.
Claims18
A blade attachment apparatus for a turbine, comprising:
- a member, which rotates about an axis of the turbine, including fore and aft disk posts that retain corresponding fore and aft turbine blades, respectively, fore and aft of a turbine nozzle and a central portion proximate the turbine nozzle;
- and
- an attachment retained between the fore disk post and the fore turbine blade and between the aft disk post and the aft turbine blades and coupled to the central portion, such that a portion of the attachment interrupts a purge flow through the turbine.
A method of assembling a blade attachment apparatus for a turbine, the method comprising:
- forming a member, for rotation about an axis of the turbine, the member including fore and aft disk posts and a central portion interposed therebetween;
- installing fore and aft turbine blades into the fore and aft disk posts, respectively, such that when the member is installed within the turbine, the turbine blades are positioned fore and aft of a turbine nozzle and the central portion;
- and
- inserting an attachment to be retained between the fore disk post and the fore turbine blade and between the aft disk post and the aft turbine blades for interruption by a portion of the attachment of a purge flow through the turbine during operations thereof.
