Patent number: 10316672Abstract: A method for fabricating an airfoil includes forming a diffuser section in an exterior surface of the airfoil. The diffuser section is defined by at least an outer surface and an inner surface that converge at a stop surface. The method also includes positioning a drilling element of a drilling device on the stop surface. The method further includes orienting the drilling element at a first angle relative to the exterior surface. The method also includes forming, using the drilling element, a cooling channel extending through the airfoil from the stop surface to an interior surface, thereby forming the cooling channel at substantially the first angle.Type: GrantFiled: September 26, 2013Date of Patent: June 11, 2019Assignee: General Electric CompanyInventors: Aaron Ezekiel Smith, John Wesley Harris, Jr.

Patent number: 9890648Abstract: A retention device for maintaining a first rotary machine component axially loaded onto a second rotary machine component in a fixed axial position includes a lock block sized and configured to move between first and second aligned recesses in the first and second rotary machine components. The aligned recesses are shaped to prevent rotation of the lock block, and the lock block has a threaded bore extending therethrough. An actuator is threadably mounted in the bore, such that rotation of the actuator will, in use, move the lock block from the first aligned recess at least partially into the second aligned recess.Type: GrantFiled: January 5, 2012Date of Patent: February 13, 2018Assignee: General Electric CompanyInventors: David Randolph Spracher, John Wesley Harris, Jr., Zachary James Taylor, Ryan Zane Ziegler, Bruce John Badding
