International Classification:

F01D 1712

US Classification:

415160

Abstract:

A compressor stator vane assemblage includes a first metal bushing disposed within a bore through the compressor casing and bolted to the casing by externally accessible bolts. A second composite bushing is disposed within the first bushing and receives the spindle of the stator vane. Reduced diameter portions of the spindle project through openings in the first and second bushings. A lever attaches to the spindle portion and is movable to rotate the vane. By removing the bolts, the first and second bushings can be removed from the casing for replacement or rotation of 180. degree. for prolonged service life without disassembly of the casing or removal of the stator vane.

Abstract:

The present disclosure generally relates to methods for additive manufacturing (AM) for fabricating multi-walled structures. A multi-walled structure includes a first wall having a first surface and a second wall having a second surface facing the first surface to define a passage having a width between the first surface and the second surface in a first direction. The multi-walled structure also includes an enlarged powder removal feature connecting the first wall and the second wall. The enlarged powder removal feature has an inner dimension greater than the width in the first direction and at least one open end in a direction transverse to the first width.

Abstract:

Described herein is a packing box for mounting on a machinery shaft. In accordance with one aspect, the packing box housing defines a central opening for insertion of a movable machinery shaft with a hollow passageway surrounding the central opening to form a path for the flow of a fluid coolant. The passageway is provided with a fluid inlet port and a fluid outlet port opening onto the outer surface of the packing box housing, and it is formed by a single conduit or by a plurality of conduits obtained through additive manufacturing process and connected in series or in parallel to wound around the central opening.

Abstract:

An additively manufactured fluid distribution manifold and a method of manufacturing the same are provided. The fluid distribution manifold includes a manifold body defining a plurality of internal passages that may extend through an insulation layer that extends at least partially around the manifold body. The insulation layer includes an external wall and an insulated wall separated by a gap, and the external wall may define a flat surface for receiving a heating element. The fluid distribution manifold may be part of a pitot static test module for testing pitot static tubes in low temperature environments.

Abstract:

A hinge assembly and a method of additively manufacturing the same are provided. The hinge assembly includes a hub defining a body and a first mounting arm and a second mounting arm each projecting from the body. The first mounting arm and the second mounting arm are spaced from one another and define a hinge axis. The hinge assembly also includes a rotatable member or vane rotatably coupled with the hub and positioned between the first mounting arm and the second mounting arm. The rotatable member defines a vane hinge member or hinge member having a first nesting feature shaped complementary to a portion the first mounting arm and a second nesting feature shaped complementary to a portion of the second mounting arm of the hub to nest the hinge member between the first mounting arm and the second mounting arm. The hub and the rotatable member are simultaneously additively manufactured as distinct, but inseparable monolithic components.

Abstract:

A shrouded impeller and a method of additively manufacturing the same are provided. In one example aspect, the shrouded impeller includes a hub and a shroud spaced from the hub. The shrouded impeller also includes a plurality of vanes extending between and connecting the hub and the shroud. The vanes are spaced circumferentially apart from one another. Flow passages are defined between adjacent vanes. In some implementations, the shrouded impeller is additively manufactured. During printing, one or more support structures are formed within and fill a portion of one or more of the flow passages to support the unsupported walls of the shrouded impeller, e.g., the shroud. Further, the support structures are removable from the shrouded impeller, e.g., after the shrouded impeller has been printed.
