摘要： An aircraft panel is provided including an outer skin (20) and an inner skin (18). The outer skin, when subject to an impact, is movable towards the first skin (18), when subject to an impact. The outer skin (20) includes stiffeners (24) that project into the cavity towards the first skin. The inner skin includes stiffeners (28) that project inwardly, of the cavity towards the outer skin (20). The outer skin contacts the stiffeners (28), when the outer skin is flexed inwardly rather than the stiffeners (24) on the outer skin contacting the inner skin. The inner skin includes a noise abatement portion.
