Abstract: A gas turbine engine includes a fan, an engine core, and an airflow duct assembly. The fan is mounted for rotation about a central axis of the gas turbine engine assembly to produce thrust for the gas turbine engine. The engine core is coupled to the fan and configured to drive the fan about the central axis. The airflow duct assembly defines a core passageway configured to conduct a first portion of air pushed by the fan into the engine core and a by-pass passageway configured to conduct a second portion air pushed by the fan around the engine core.

The impeller structure includes a near axial discharge configuration thus reducing the overall size of the envelop surrounding the compressor assembly. The impeller structure may have axial exit vanes.

Abstract: A header conduit assembly for a sediment collecting apparatus includes a tubular member having a plurality of mutually spaced (suction) orifices disposed in a linear array extending parallel to an axis of the tubular member. The conduit assembly further includes at least one elongate deflector member mounted to the tubular member in effective proximity to at least some of the orifices to guide sediment toward the orifices during a sediment evacuation process. Preferably, the deflector member extends parallel to the axis of the tubular member. Inasmuch as the tubular conduit member extends perpendicularly to a direction of movement of the conduit assembly on the floor of a clarification basin or tank, the deflector is oriented orthogonally to the path of the conduit assembly.
