Structural Arrangement and Method of Fabricating A Composite Trailing Edge Control Surface

摘要

The present disclosure is generally directed to a composite trailing edge control surface including a contiguous one-piece composite control surface skin wrapped around a plurality of stiffening cores, a plurality of hinge fittings, and a plurality of substantially parallel ribs. The contiguous one-piece composite control surface skin provides a control surface on opposing sides of the trailing edge control surface and substantially distributes bending, shear and torsion loads of the trailing edge control surface to the plurality of hinge fittings and the plurality of substantially parallel ribs. A method of manufacturing the trailing edge control surface includes positioning a contiguous one-piece composite control surface skin on a substantially flat tool. A plurality of stiffener cores having a plurality of thin covering skins are positioned on the contiguous one-piece composite control surface skin and are cured to create a laminate sandwich composite structure skin that is trimmed and has fastener apertures and hinge fitting access apertures provided there-through.

主权项

1. A composite trailing edge control surface comprising:
a contiguous one-piece composite control surface skin; a plurality of stiffening cores bonded to the contiguous one-piece composite control surface skin; a plurality of hinge fittings fastened to the contiguous one-piece composite control surface skin; and a plurality of substantially parallel ribs fastened to the contiguous one-piece composite control surface skin, wherein the contiguous one-piece composite control surface skin being enclosed around the plurality of stiffening cores, and wrapped around the plurality of hinge fittings and the plurality of substantially parallel ribs provides a control surface on opposing sides of the trailing edge control surface and substantially distributes bending, shear and torsion loads of the trailing edge control surface to the plurality of hinge fittings and the plurality of substantially parallel ribs.
