Abstract
A gas turbine engine including a bypass duct defined by radially outer and inner walls, the radially inner wall defined by acoustic panels. The acoustic panels define the outer wall of a heated fire zone. In conventional engines an insulating blanket is attached to the panels, however, this is heavy and costly. Cooling film means are configured to pass bypass air through and over an internal surface of the panel.
