1. An assembly for an aircraft propulsion system, comprising:
a nacelle inlet structure including an inner inlet opening, an outer inlet opening and a rotating structure;
the rotating structure extending circumferentially about the inner inlet opening;
the rotating structure configured to rotate about an axis between a first position and a second position, wherein the rotating structure at least partially closes the outer inlet opening in the first position, and the rotating structure at least partially opens the outer inlet opening in the second position;
the rotating structure forming an outer peripheral boundary of the inner inlet opening; and
the rotating structure forming an inner peripheral boundary of the outer inlet opening.
