A variable area vane arrangement includes a stator vane, a bushing and a vane platform with an aperture. The stator vane rotates about an axis, and includes a shaft that extends along the axis into the aperture. The bushing is connected to the shaft, and is arranged within the aperture between the vane platform and the shaft.

A method of evaluating an article includes measuring a feature of the article using a defect detection device. A set of data points is recorded representing the first feature and the set of data points is analyzed. The analyzing includes constructing a filtered curve by constructing a raw curve by listing the set of data points, constructing a first meanline curve, and finding a first difference between the raw curve and the first meanline curve. The analyzing also includes constructing a reversal curve by calculating a second derivative of a meanline curve constructed from the set of data points. The method also includes deciding the acceptability of the feature of the article.

A method for welding a first powder metallurgical (PM) part to a second powder metallurgical (PM) part includes: working a first face of the first PM part; working a first face of the second PM part; and friction welding the first face of the first part to the first face of the second part.

An airfoil including an airfoil body, a recessed portion of a first depth in a first side of the airfoil body, the recessed portion including a plurality of pockets of a second depth located within the recessed portion and ribs of the first depth located between the pockets, a cover configured to fit into the recessed portion such that an interior surface of the cover engages the ribs and an exterior surface of the cover is about flush with an exterior surface of the first side of the airfoil body, and a high energy beam weld configuration extending through the cover and into the ribs and positioned to attach the cover to the ribs.
