Abstract
An acoustic panel for integration in a nacelle of an aircraft engine assembly for absorbing noise generated by an engine or a fan assembly of the aircraft engine assembly. The acoustic panel comprises a generally annular section integrated into or attached to an inner wall of the inlet section, and a flange extending generally perpendicularly from the annular section. The flange attaches the acoustic panel to a bulkhead without requiring the use of fasteners extending through the annular section of the acoustic panel, thus eliminating any unwanted air passages through the annular section of the acoustic panel.
