Title: Insert system for an airfoil and method of installing same

Abstract

An insert system for an airfoil is provided. The airfoil includes a plenum that extends into an aft portion of the airfoil. The plenum includes a plenum inlet and an entirety of the plenum inlet is defined axially forward of the aft portion. The insert system includes a first and second insert. The first insert and the second insert include a plurality of impingement openings defined therein. The first insert includes a first neck portion. The first insert is sized for insertion into the plenum radially through the plenum inlet and the first insert is movable aftward within the plenum into an installed position such that the first neck portion is positioned aftward in the plenum inlet. The second insert is sized for insertion into the plenum radially through the plenum inlet forward of the first neck portion in the installed position.

Method for controlling coolant flow in airfoil, flow control structure and airfoil incorporating the same

Patent Itzel, Gary Michael; Devine, II, Robert Henry; Chopra, Sanjay; ...

A coolant flow control structure is provided to channel cooling media flow to the fillet region defined at the transition between the wall of a nozzle vane and a wall of a nozzle segment, for cooling the fillet region. In an exemplary embodiment, the flow control structure defines a gap with the fillet region to achieve the required heat transfer coefficients in this region to meet part life requirements.

Gas turbine nozzle vane insert and methods of installation

Patent Miller, William John [Simpsonville, SC]; Predmore, Daniel Ross [Clifton Park, NY]; Placko, James Michael [West Chester, OH]

A pair of hollow elongated insert bodies are disposed in one or more of the nozzle vane cavities of a nozzle stage of a gas turbine. Each insert body has an outer wall portion with apertures for impingement-cooling of nozzle wall portions in registration with the outer wall portion. The insert bodies are installed into the cavity separately and spreaders flex the bodies toward and to engage standoffs against wall portions of the nozzle whereby the designed impingement gap between the outer wall portions of the insert bodies and the nozzle wall portions is achieved. The spreaders are secured tomore »« less

Turbine airfoil having near-wall cooling insert

Patent Martin, Jr., Nicholas F.; Wiebe, David J.

A turbine airfoil is provided with at least one insert positioned in a cavity in an airfoil interior. The insert extends along a span-wise extent of the turbine airfoil and includes first and second opposite faces. A first near-wall cooling channel is defined between the first face and a pressure sidewall of an airfoil outer wall. A second near-wall cooling channel is defined between the second face and a suction sidewall of the airfoil outer wall. The insert is configured to occupy an inactive volume in the airfoil interior so as to displace a coolant flow in the cavity towardmore »« less
