METHOD FOR REPAIRING AT LEAST A PORTION OF AN ACOUSTIC PANEL FOR A NACELLE

摘要

The invention relates to a method for repairing at least a portion of an acoustic panel for a nacelle (1) of an aircraft turbojet engine (6), said panel comprising an acoustic skin (104) in which a plurality of acoustic holes (106) are drilled, a solid skin (112), and a cellular acoustic structure (108) comprising a plurality of cells (110), each of which has one or more drainage openings (132) arranged in one or more of the walls forming each cell (110), said structure (108) being arranged between the acoustic skin (104) and the solid skin (112), said method comprising, in particular, a step in which a resin (130), which is capable of hardening at ambient temperature, is injected through the acoustic holes (106) of the acoustic skin (104), said holes (106) terminating in complete cells (124) adjacent to junction cells belonging to the cut acoustic panel (100) so as to block the drainage openings (132) of said junction cells (122), said junction cells (122) being intended to be in contact with the cutting area (102).
