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.
Claims18
A nacelle for partially enclosing an aircraft engine and fan assembly, the nacelle comprising:
- an inlet section for directing air toward the fan assembly;
- a main section coupled with the inlet section for supporting the engine;
- and
- an acoustic panel for absorbing noise generated by the engine or the fan assembly, the acoustic panel including-
- 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 for attaching the acoustic panel to a bulkhead without requiring the use of fasteners extending through the annular section.
