1. An assembly for an aircraft propulsion system, comprising:
a nacelle inlet structure extending axially along and circumferentially about an axis, the nacelle inlet structure including an inlet lip, an inner barrel, an outer barrel and a plurality of supports;
the inlet lip forming a leading edge of the nacelle inlet structure, the inlet lip including an outer aft end;
the inner barrel projecting axially aft away from the inlet lip;
the outer barrel projecting axially aft away from the inlet lip, the outer barrel including a mounting flange, the mounting flange connected to the outer aft end forming an interface between the outer barrel and the inlet lip, and the outer barrel radially outboard of and axially overlapping the inner barrel; and
the plurality of supports arranged circumferentially about the axis in an array and configured to support the outer barrel, each of the plurality of supports extending longitudinally along the axis, each of the plurality of supports extending radially between and connected to the inner barrel and the outer barrel, and forward ends of the plurality of supports disposed aft of the interface between the outer barrel and the inlet lip.
