Abstract
Abstract The invention relates to a means for containing burst fragments generated when very high speed machinery, particularly gas turbines, rupture. The containment means is a winding of tape over the machinery housing and radially aligned along the expected path of travel of part fragments. The winding is formed from lightweight material having high strength and high elongation properties providing unusual energy absorbing capabilities which tends to contain the impact of burst fragments primarily by deflection rather than high yield stresses.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
48 words
A burst containment means comprising the combination of a housing about a rotated bladed structure, a winding on said housing consisting essentially of at least 15 overlapping turns of a tape formed from a nylon ballistic material having a specific energy absorbing capability of at least 200,000 (INLB/LB).
Claim 2
Dependent Claim
