Abstract:
Gas turbine engine systems involving fairings with locating data are provided. In this regard, a representative a fairing assembly for a gas turbine engine includes: a first locating component having a leading edge, first and second sides extending from the leading edge, and a recess oriented parallel to the leading edge, the recess having a first datum surface, the first locating component being operative to be positioned between a portion of a strut and a portion of an interior surface of a fairing sheath such that the first datum surface establishes a desired orientation of the fairing sheath relative to the strut.
Abstract:
An inlet guide vane (30) provides improved, smooth airflow and avoids separation of flow even at high incidence angles. The inlet guide vane (30) includes a strut (32) having opposite side surfaces (46,48) that are continuously curved to provide a controlled velocity distribution at the trailing edge (44) of the strut (32). The inlet guide vane (30) further includes a flap (34) having a leading edge (52) aligned behind the trailing edge (44) of the strut (32). Generally, the strut (32) and the flap (34) are designed together so that low momentum air in the gap (59) between the strut (32) and the flap (34) will be energized and entrained in the boundary layer of the flap (34). The airflow from the gap (59) will remain attached to the flap (34) to improve the flow from the flap (34).

Abstract:
A guide vane includes an airfoil with a first end and a second end. A platform is disposed at a first end of the airfoil, and a K-gusset is disposed on the platform opposite the airfoil. The K-gusset includes four bosses and ribs extending between the bosses in a “K” configuration.
Abstract:
A static guide vane for use in a fan section of a gas turbine engine includes an outer platform and an inner platform. The inner and outer platforms are connected by an airfoil. The airfoil have channels extending into a main body of the airfoil to reduce the weight of the vane. A cover closes off the channels with the cover providing a portion of the airfoil.
Abstract:
A structural guide vane for use in a gas turbine engine has a leading edge section, a trailing edge, a pressure surface and a suction surface. An erosion coating such as polyurethane resin is on the pressure surface and the suction surface. The leading edge of the vane is without the erosion coating and is bare metal. The vane is formed to include a plurality of pockets and bond shelves in the pressure surface side, and an epoxy bond line on the bond shelves holding a cover plate protected by the erosion coating.
Abstract:
A device for providing a grounding path between an outer surface of a gas turbine aircraft engine and an inner surface of a gas turbine aircraft engine uses a structural guide vane (SGV) with a nonconductive coating on the surface. Bolts are put in bolt holes that have a bolt receiving cavity without the nonconductive coating. A washer and bolt are used so that attachment of the SGV to a surface provides a ground path from the SGV through the bolt, washer and nut for electrical engagement with a surface to which the bolt attaches the SGV.
