Outer barrel support structure for nacelle inlet structure

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, a bulkhead, a cavity and a support structure;
• the inlet lip forming a leading edge of the nacelle inlet structure;
• the inner barrel connected to the inlet lip at an inner connection;
• the outer barrel connected to the inlet lip at an outer connection, and the outer barrel radially outboard of and axially overlapping the inner barrel;
• the bulkhead radially between and connected to the inner barrel and the outer barrel;
• the cavity extending radially within the nacelle inlet structure from the inner barrel to the outer barrel, and the cavity extending axially within the nacelle inlet structure from the bulkhead to the inlet lip;
• and
• the support structure disposed within the cavity, the support structure supporting the outer barrel, the support structure disposed aft of the outer connection and the inner connection, and the support structure formed by a plurality of discrete axially extending supports arranged and spaced apart circumferentially about the axis in an array.

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, a cavity, a support structure and an electric heater configured with an exterior skin of the inlet lip;
• the inlet lip forming a leading edge of the nacelle inlet structure;
• the inner barrel connected to and projecting axially aft away from the inlet lip at a first interface;
• the outer barrel connected to and projecting axially aft away from the inlet lip at a second interface, and the outer barrel radially outboard of and axially overlapping the inner barrel;
• the cavity extending radially within the nacelle inlet structure from the inner barrel to the outer barrel, and the cavity extending axially within the nacelle inlet structure to a portion of the inlet lip forming the leading edge;
• and
• the support structure disposed within the cavity and supporting the outer barrel, the support structure disposed axially downstream of the first interface and axially downstream of the second interface, and the support structure formed by a plurality of discrete axially extending supports arranged and spaced apart circumferentially about the axis in an array.
