Abstract: A method of evaluating and validating additive manufacturing operations includes generating a multidimensional space defined by a plurality of bounds, each of the bounds being defined on a distinct parameter of an additive manufacturing process and each of the parameters affecting the occurrence of a keyhole porosity flaw, each of the parameters being a dimension in a multi-dimensional coordinate system, determining a coordinate position of at least one additive manufacturing operation within the multi-dimensional coordinate system, and categorizing the operation as free of keyhole porosity flaws when the coordinate position is within the multi-dimensional space.

Abstract: A vibration resistant fan guide vane for a gas turbine engine is provided. The fan guide vane comprises a vibration damping component made of a MAXMET composite. The damping component may be a cover that covers some or all of the fan guide vane body. Alternatively, portions of the fan guide vane body or the entire vane body may be made from MAXMET composites. The disclosure makes use of the ultrahigh, fully reversible, non-linear elastic hysteresis behavior that MAXMET composites exhibit during cyclic elastic deformation in order to damp vibration.

Abstract: A method for treating a surface of a contoured titanium substrate used for adhesively bonded engine components. The method including applying energy from a fiber laser system to a contoured surface of a titanium substrate, the laser energy is distributed to the contoured titanium surface by at least one of direct light of sight, reflection, or scattering of one or more laser beam.

Abstract: A method of evaluating and validating additive manufacturing operations includes generating a multidimensional space defined by a plurality of bounds, each of the bounds being defined on a distinct parameter of an additive manufacturing process and each of the parameters being directly related to the occurrence of a horizontal lack of fusion flaw, each of the parameters being a dimension in a multi-dimensional coordinate system, determining a coordinate position of at least one additive manufacturing operation within the multi-dimensional coordinate system, and categorizing the operation as free of horizontal lack of fusion flaws when the coordinate position is within the multi-dimensional space.
