Claims8
A laminated composite intake cowl of a nacelle assembly, the assembly comprising:
- a first laminated composite component;
- a second component;
- a third component that is a laminated composite component;
- an annular bushing bonded to the first laminated composite component;
- a second annular bushing bonded to the third component;
- a fastener through the annular bushing to at least partially retain the first laminated composite component to the second component;
- a second fastener through the second annular bushing to at least partially retain the third component to the second component,
- wherein the first laminated composite component is an outer component,
- wherein the second component is a bulkhead, and
- wherein the third component is an inner component,
- wherein a first surface of the annular bushing extends above a first surface of the first laminated composite for a distance by which a second surface of the annular bushing is recessed relative to a second surface of the first laminated composite component.
