ABSTRACT:
A rupture prevention ring consists of two coaxially arranged, spaced-apart stiff end rings wrapped in several layers of fiber cloth. Resin bonding is used around the end rings while in the intermediate area between the end rings, the fibers are not free of resin and hence not stiffened. Owing to the high energy absorption capability of the structure including the elastic yielding of the fibers without the resin, an excellent containment ability is obtained at a low weight. Fragments are effectively retained without jeopardizing the rotating blade and disk assembly of the damaged stage.
