Abstract
An acoustic structure includes at least a pair of adjacent panels. The panels have edges, and the panels define a plurality of cells. A first of the at least a pair of acoustic panels is connected to a second of the pair of acoustic panels at adjacent ones of the edges. There is a pair of spaced faces in each acoustic panel between which the plurality of cells extend. There are openings in each of the edges of each of the adjacent acoustic panels, and between a first of the faces and a second of the faces. A securing member extends through the openings in each of the first and the second of the adjacent acoustic panels. A gas turbine engine is also disclosed.
Claims11
A gas turbine engine comprising:
- a core engine including a compressor and a turbine;
- acoustic structure positioned on a surface of the gas turbine engine, and the acoustic structure including at least a pair of adjacent panels, said panels having edges, and said panels each defining a plurality of cells, a first of said at least a pair of acoustic panels connected to a second of said pair of acoustic panels at adjacent ones of said edges;
- there being a pair of spaced faces in each acoustic panel between which the plurality of cells extend, and there being openings in each of said edges of each of said adjacent acoustic panels, and between a first of said faces and a second of said faces, with the openings being spaced from both said first of said faces and said second of said faces with a securing member extending through said openings in each of said first and said second of said adjacent acoustic panels;
- and
- wherein the acoustic structure and the at least a pair of adjacent panels form a full-hoop structure centered on a rotational axis of the core engine.
