Abstract

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.
