Abstract
A bypass air passage can be provided between a radially-outer wall of a bypass duct and an engine core, the radially-outer wall having a first, radially inner skin apertured and exposed to the bypass air passage, and a second skin radially-outwardly offset from the first skin, the second skin having an aperture blocked by a thermal fuse, wherein the thermal fuse is configured to melt upon reaching a threshold temperature, thereby opening a gas path from the bypass air passage across the second skin, via the aperture.
