The invention concerns a turbine engine with an axis of rotation B comprising a blower casing ( 10 ) and a blower (V) with movable blades ( 17 ). A clearance lies between the internal surface of the casing and the free ends of the blades. A bearing of the blower is connected to fixed parts of the turbine engine by connections such that, in the event of a load on the blower blades, these connections break and the axis of rotation of the blower oscillates about the axis of rotation B. The casing comprises, bonded to its internal surface and over at least part of the extent of the clearance, a layer of thermoformable foam ( 19 ) placed opposite the ends of the blades ( 17 ) of the blower (V). The layer of thermoformable foam ( 19 ) is partly covered with a layer of abradable substance ( 14 ), the thickness of the layer of abradable substance ( 14 ) is such that the free ends of the blades of the blower do not reach the layer of foam during the normal functioning of the turbine engine, and, in the event of a load on the blower, the free ends of the blades at least partly fragment the layer of abradable substance.
