A swan neck duct is a jet engine component, usually situated within the compression or turbine expansion system.
Many jet engines have a short annular passageway, linking two components, where there is a large change in mean radius, from front to rear. The shape of the resulting passageway is often similar to that of a swan or goose neck. Consequently, such a passageway is called a swan (or goose) neck duct.

Upon a fading gleam,
Float out upon a long
Last reach of glittering stream
And there sing his last song.”

And wild for to hold though I seem tame.””
