Claims9
Safety device for a rotating element of a turbine engine located in the casing of an engine and having rotating blades, comprising a ring surrounding a stage of blades, upon which is wound an elongated element, said ring being capable of being traversed by a fragment of a ruptured blade or a blade that has been detached and which strikes the elongated element, and wherein the windings of said elongated element move to absorb the kinetic energy, the improvement comprising:
- starting from the innermost layer an internal envelope, a first ring of segments made of a deformable material, a winding of an elongated element encased in a polymerizable material, a second ring of segments made of a deformable material and a thin external envelope.
