Abstract

Aspects of the disclosure are directed to a system that includes a boot configured to attach to a chevron of an aircraft nacelle, and an attachment mechanism configured to attach the boot and the chevron. In some embodiments, a boot includes a first surface and a second surface, where the surfaces are attached by inwardly tapering sidewalls that form an opening that is configured to surround a chevron of an aircraft nacelle. In some embodiments, a repair of a chevron on an exhaust nozzle of an aircraft engine includes placing a chevron-shaped boot with a pocket over at least a portion of a chevron structure on an exhaust nozzle of an aircraft engine, the pocket having a shape that generally conforms to an external surface of the chevron, covering the portion of the chevron structure with the boot, and fastening the boot to the chevron through at least one of bonding or mechanical fastening.
