Abstract
The fan cowl () of a ducted fan gas turbine engine () has a downstream portion including an inner casing () that surrounds a honeycomb structure () in abutting engagement. Honeycomb structure () is made up of a number of closely spaced honeycomb blocks () fixed about a liner (), one or more of which blocks, if struck by a broken fan blade portion, will move relative to those not struck, in a radially outward direction, thus reducing the crushing force of the blow, and only flexing casing () instead of permanently deforming or puncturing it.
