Abstract:
1. A thrust reverser inner fixed structure, comprising: an inner skin; an outer skin; a cellular core disposed between the inner skin and the outer skin; and a reinforcement lattice comprising a plurality of reinforcement members extending in a thickness direction through the cellular core between the inner skin and the outer skin configured to reduce at least one of cracking or delamination of the inner fixed structure, wherein each of the reinforcement members also extends in lateral direction of the cellular core, lateral directions associated with a first set of reinforcement members intersecting lateral directions associated with a second set of reinforcement members to thereby form the reinforcement lattice; and wherein the reinforcement lattice is provided only in an enlarged barrel portion of the inner fixed structure, the enlarged barrel portion being located between an upper bifurcation wall portion and a lower bifurcation wall portion of the inner fixed structure, wherein each reinforcement member comprises: a central segment extending radially through the cellular core, the central segment having a first end and a second end; and a first end segment extending from the first end of the central segment substantially parallel to the inner skin and bonded to the inner skin, wherein the second end of the central segment abuts the outer skin, the outer skin is not bonded to the second end, wherein the outer skin is free from bonding to any of the reinforcement members.
