An assembly for an aircraft propulsion system includes a nacelle inlet structure. The nacelle inlet structure includes an inlet lip, an inner barrel, an outer barrel, a bulkhead and a plurality of structure segments. Each of the structure segments includes an exterior skin, an inner mount flange, an outer mount flange and an electric heater configured to heat the exterior skin. The exterior skin forms at least a respective circumferential section of the inlet lip. The inner mount flange is connected to and projects radially outward away from the exterior skin. An inner fastener extends axially through the inner mount flange and couples the inner mount flange to the inner barrel. The outer mount flange is connected to and projects radially inward away from the exterior skin. An outer fastener extends axially through the outer mount flange and couples the outer mount flange to the bulkhead.

Segmented nacelle inlet lip with electric anti-icing system

An assembly is provided for an aircraft propulsion system. This assembly includes a nacelle inlet structure which extends axially along and circumferentially around a centerline. The nacelle inlet structure includes an inlet lip, an inner barrel, an outer barrel and a plurality of structure segments. The inlet lip forms a leading edge of the nacelle inlet structure. The inner barrel projects axially aft away from the inlet lip. The outer barrel projects axially aft away from the inlet lip. The outer barrel is radially outboard of and axially overlaps the inner barrel. Each of the structure segments includes an exterior skin, a mount and an electric heater configured to heat the exterior skin. The exterior skin forms a respective circumferential section of the inlet lip and a respective circumferential section of the outer barrel. The mount is bonded to the exterior skin and mechanically attached to the inner barrel.
