  • Machine vision acoustic panel repair with retention of acoustic properties
    Patent number: 11104086
    Abstract: An acoustic panel (200) for an aircraft nacelle (100) may comprise a perforated first skin (220), a second skin (230), and a core (210) sandwiched between them. A camera system (330) may scan a perforation pattern of a damaged portion (311) of the perforated first skin (220). The damaged portion (311) of the perforated first skin (220) may be removed. A replacement patch (660) may be formed. A CNC machine (450) may drill the replacement patch (660) according to the perforation pattern. The perforations (425) in the replacement patch (660) may be aligned with perforations (325) in the perforated first skin.

  • Acoustic panel repair with retention of acoustic properties
    Patent number: 10752380
    Abstract: An acoustic panel (200) for an aircraft nacelle (100) may comprise a perforated first skin (220), a second skin (230), and a core (210) sandwiched between them. A damaged portion of the perforated first skin may be removed. A fiberglass ply (510) may be coupled to the acoustic panel. A pressure differential may cause the fiberglass ply to form dimples (515) within the perforations (325) of the first skin. The fiberglass ply may be used as a template to drill holes in a replacement patch (400).
