Title:
STRUCTURAL ARRANGEMENT AND METHOD OF FABRICATING A COMPOSITE TRAILING EDGE CONTROL SURFACE
Document Type and Number:
WIPO Patent Application WO/2015/156857
Kind Code:
A3
Abstract:
The present disclosure is generally directed to a composite trailing edge control surface (600) including a contiguous one-piece composite control surface skin (200) wrapped around a plurality of stiffening cores (300), a plurality of hinge fittings (400), and a plurality of substantially parallel ribs (500). 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 (200) on a substantially flat tool. A plurality of stiffener cores (300) 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 (350) that is trimmed and has fastener apertures and hinge fitting access apertures (210) provided there-through.
