Abstract: An applicator assembly for applying a liquid to at least one fastener includes a housing, a vat body, at least one applicator roller pair, and at least one removal roller pair. The housing includes a sidewall assembly. The sidewall assembly extends between and to a bottom end and a top end. The vat body is disposed within the sidewall assembly. The vat body extends between and to a bottom side and a top side. The vat body forms a liquid cavity at the top side. The at least one applicator roller pair is disposed within the liquid cavity. The at least one applicator roller pair includes a first applicator roller and a second applicator roller. The at least one removal roller pair is disposed between the liquid cavity and the top end. The at least one removal roller pair includes a first removal roller and a second removal roller.

Abstract: An article includes a ceramic matrix composite (CMC) vane arc segment for disposal about an engine central axis. The CMC vane arc segment includes first and second platforms and an airfoil section that extends therebetween. The airfoil section defines a radial stacking axis that is oblique to a Z-axis that is perpendicular to the engine central axis such that the radial stacking axis forms a non-zero angle with the Z-axis.

Abstract: During a manufacturing method, a workpiece is provided that includes a face surface and a back surface. A first aperture is machined into the workpiece using an energy beam. The first aperture projects partially into the workpiece from the face surface to an end of the first aperture. A waterjet is directed into the first aperture to machine a second aperture into the workpiece. The second aperture extends from the end of the first aperture to the back surface.

Abstract: A manufacturing method is provided during which an aperture is machined into workpiece using a laser beam. An image of an interaction between the laser beam and the workpiece is captured during the machining of the aperture using a camera with an electronic shutter. A parameter associated with the aperture is determined based on information from the image.

Abstract: A gas turbine engine is provided and includes a first rotor element defining a groove, a second rotor element disposed to rotate about the first rotor element and a piston seal ring (PSR) disposed in the groove to form a seal between the first rotor element and the second rotor element. The second rotor element is formed to define bypass flow channels about the PSR that extend between opposite axial sides of the PSR.

Abstract: A fan has a rotating bulge defining a radially outermost point of the rotating cone relative to a rotational axis. The rotating bulge is defined by a radially outwardly extending forward portion leading to the radially outermost point on the bulge and then a radially inwardly extending portion aft of the radially outermost point of the bulge leading into the core engine path within the splitter housing. The core splitter housing has a leading edge, and the bulge radially outermost point being upstream of the leading edge of the splitter housing. The bulge radially outermost point is a first radial distance from a rotational axis, and the leading edge of the splitter housing being at a second radial distance of the rotational axis, and a ratio of the first radial distance to the second radial distance being at least 0.95.

Abstract: A metallic seal ring has a cross-section of a “6” or “9” shape with an open loop and an extension therefrom. The open loop is seated in a groove of an inner member and, in cross-section has three spaced contact locations with the groove at a first sidewall surface, a second sidewall surface, and a base surface, respectively with gaps between the contact locations. The seal extension has a fourth contact location with an inner surface of an outer member axially beyond a span between the first and second sidewall surface contact locations.
