Method of forming hollow channels within a component
TL;DR: In this paper, the authors proposed a method of forming an internal channel within an article, such as a cooling channel in an air-cooled blade, vane, shroud, combustor or duct of a gas turbine engine.
Patent
Airfoils with improved strength and manufacture and repair thereof
Melvin Robert Jackson,Aaron Todd Frost,S. C. Huang,Charles Gitah Mukira,Thomas Robert Raber,Raymond Alan White,Paul Leonard Dupree,Canan Uslu Hardwicke +7 more
TL;DR: In this paper, the authors presented a repair method for a gas turbine airfoil with specified nominal dimensions, which is based on removing at least a portion of at least one section of the airframe to create at least 1 deficit of material relative to the specified nominal dimension, and then inserting a second material, having a creep life that is at least substantially equal to the creep life of the first material, and a fatigue life equal to fatigue life.
Patent
Method for repairing superralloy castings using a metallurgically bonded tapered plug
TL;DR: In this paper, a mating tapered plug is prepared such that the plug can fit into the aperture so that the sloped side walls of the plug evenly and unilaterally rest on frusto-conical sides of the aperture.
Patent
Method of forming high-temperature components and components formed thereby
TL;DR: In this article, a method for forming an exterior surface of a high-temperature component, such as a blade or vane of a gas turbine engine, is presented. But this method does not consider the service conditions of the component.
Patent
Electroslag apparatus and guide
Mark Gilbert Benz,William Thomas Carter,Paul Leonard Dupree,Howard Roscoe Hart,Bruce Alan Knudsen,Janel Koca Browning,Russell Scott Miller,Robert John Zabala +7 more
TL;DR: In this article, a melt guide is provided for enclosing a bottom of an electroslag refining crucible containing a melt of refined metal, and a base plate is sized to have a perimeter to engage the crucible bottom for attachment.
