Abstract: Gas turbine engines are provided that include an annular splitter nose structure configured to impinge an accelerated air stream within the gas turbine engine and separate the accelerated air stream into a primary air stream directed into a core duct and a secondary air stream directed into a bypass duct. The splitter nose structure may include a leading edge that is pitched radially outward relative to a rotational axis of the gas turbine engine at a pitch angle of between about 0.5 and 20 degrees. The splitter nose structure may include an irregular cross-sectional shape.

Abstract: A diffuser and deswirl flow structure includes a plurality of tube structures with an outer wall that is hollow and elongate and that extends between a first portion and a second portion. The plurality of tube structures is disposed in an annular arrangement about the longitudinal axis. The flow structure also includes a plurality of flow passages extending through the tube structures. The plurality of flow passages extend from the first portion to the second portion, respectively. The plurality of flow passages respectfully include a diffuser portion, which is proximate the first portion and configured to diffuse a fluid flow from a compressor wheel. The plurality of flow passages respectfully include a deswirl portion, which is proximate the second portion and configured to deswirl the fluid flow from the diffuser portion. The outer wall defines the diffuser portion and the deswirl portion. The outer wall is self-supporting.
