Low deflection fan case containment fabric

摘要

A turbine engine fan casing (10) for containing a separated blade fragment comprising a support case (12) having an axially extending impact zone, a substantially structurally continuous penetrable covering (24) circumscribing the impact zone; and a containment covering (28) circumscribing the penetrable covering (24). The containment covering (28) comprises a textile fabric containing threads (36, 38) in a warp direction and a fill direction, wherein the threads (36) in the warp (38) direction are of a different denier than the threads in the fill direction.
