A powder bed additive layer manufacturing apparatus for manufacturing a component, the apparatus including a base plate including a set of axes X, Y, Z and a first re-coater blade. The base plate includes a build surface for receiving powder, and the build surface includes a non-planar surface profile for complementing the shape of a component non-planar surface. The first re-coater blade has a blade profile that corresponds with a non-planar surface profile of the build surface. The first re-coater blade is configurable such that it can traverse across the build surface, for providing a layer of powder having a consistent depth across the non-planar build surface during the manufacturing process.

A system for an outlet guide vane assembly and method of assembly thereof are provided herein. The outlet guide vane assembly generally includes a composite outlet guide vane that includes a monolithic body extending in an axial direction from a base to a top, as well as an anchor bracket. At least one of the base and the top includes a bulbous profile having a thickness in a radial direction that is greater than a thickness of the monolithic body in the radial direction, where the radial direction is orthogonal to the axial direction. The anchor bracket generally includes an anchor base, an engagement slot, and at least one side structure defining the engagement slot.

An airfoiled component comprises: a root section, an airfoil section, a damper pocket enclosed within a portion of the airfoil section, and a damper. The airfoil section includes a suction sidewall and a pressure sidewall each extending chordwise between a leading edge and a trailing edge, and extending spanwise between the root section and an airfoil tip. The damper includes a fixed end unified with a damper mounting surface, and a free end extending into the damper pocket from the damper mounting surface.

A rotor for a machine under this disclosure could be said to include a hub having a plurality of blades extending radially outwardly of the hub. At least one of the hub and the plurality of blades is formed of at least two metal materials. The two metal materials are selected to have different thermal expansion coefficients such that the overall rotor will be more resistant to forces it may experience as temperature or speed increases. There are layers of each of the two metal materials, with an intermediate gradient wherein the two materials are mixed. Alternatively, a shape memory alloy may be used. A method is also disclosed.
