SUPPORT COLLAR GEOMETRY FOR LINEAR FRICTION WELDING |
摘要 |
An example method of attaching an airfoil for an integrally bladed rotorincludes placing a support collar in an installed position around at least a leading edge and trailing edge of an airfoil stub to be repaired in an integrally bladed rotor. The support collar and the airfoil stub together have a midline that is positioned between opposing, laterally outer surfaces of the airfoil stub when the support collar is in theinstalled position. The method performs linear friction welding to add a replacement airfoil to the airfoil stub.Figure 1 |
