Claim 0:
1. An acoustic panel for a gas turbine engine, the acoustic panel comprising
a panel body including an outer body section having a first axial length and an inner body section having a second axial length greater than the first axial length,
a panel-body cover including a radially outer skin coupled to the outer body section of the panel body and a radially inner skin coupled to the inner body section of the panel body, and
a forward support bracket coupled to a forward end of the panel body and arranged radially between the radially outer skin and the radially inner skin, the forward support bracket including an attachment flange that extends axially forward away from the outer body section, and a panel-body support including an outer radially-extending strip coupled to the outer body section and the attachment flange, an inner radially-extending strip coupled to the inner body section, the inner radially-extending strip disposed forward of the outer radially-extending strip, and an outer axially-extending strip including an aft end and a forward end, the aft end coupled to the outer radially-extending strip and the forward end coupled to the inner radially-extending strip, the outer axially-extending strip coupled to the inner body section,
wherein the panel-body support is coupled to the inner body section of the panel body and at least partially spaced apart from the attachment flange to provide a radial cavity between the attachment flange and the panel-body support, the radial cavity defined by the attachment flange, the outer axially-extending strip, and the outer radially-extending strip, wherein the panel-body support is disposed between the panel body and the radial cavity such that the radial cavity opens axially forward from the forward end of the panel body.
