ABSTRACT:
An assembly for a rotating composite inlet nose cone is reinforced or is repaired after having undergone delamination. The assembly strengthens the inlet nose cone and thus blacks delaminations of the inlet nose cone. In one particular embodiment, the assembly includes an outer ring that blacks delaminations in an undamaged rotating inlet nose cone. The outer ring has a higher stiffness to mass ratio than the adjacent portion of the inlet nose cone assembly. In one detailed embodiment, an inner ring is disposed inwardly of the adjacent portion of the inlet nose cone assembly. The inner ring in one detailed embodiment has a lower stiffness to mass ratio than the outer ring.
