ABSTRACT:
A burst guard ring for stopping and retaining blade fragments thrown from a failing rotor of a turbine engine includes an outer fiber belt of a highly elastic material, preferably aramid fibers in a silicone rubber matrix surrounding the engine housing. Ceramic tiles are provided radially inwardly of the fiber belt or in the fiber belt exclusively at certain critical locations where any bulging of the fiber ring due to blade fragment impact would damage auxiliary devices or pipelines arranged adjacent or close to the engine at such critical locations. In non-critical areas the fiber belt provides sufficient protection without the ceramic tiles. The high energy absorbing protective effect of elastic fibers is advantageously combined with the low straining or expansion of ceramic, so that a low total weight is achieved.
