    摘要: This invention relates to an improved composite material leading edge/spar member for an aircraft control surface, and the like. The present invention provides a one-piece composite leading edge/spar member that is of a lighter and stronger construction offering dimensional stability, and an efficient method for manufacturing the same is also provided. A one-piece leading edge/spar member (12) includes a forward leading edge portion (22), and an aft spar portion (23). The forward leading edge and the aft spar portions are connected together as a continuous one-piece tubular member of composite material. The forward leading edge portion (22) may be rounded, and the aft spar portion (23) may include an aft web portion (24) and first and second rebate portions (26, 28). The rebate portions (26, 28) connect the web portion (24) to the rounded forward leading edge portion (22), and provide surfaces for the attachment of skin surface members (16, 18) thereto.

    摘要: A device for automated composite lay up of a part to be manufactured—such as a large aircraft fuselage—includes a mandrel having a vertical axis and an interior mandrel surface that conforms to an outside mold line of the part. A vertical movement shaft is disposed inside the mandrel. A platform is supported, moved up and down, and rotated on the vertical movement shaft. One or more arm mechanisms are attached to the platform. One or more material delivery heads are supported by the arm mechanisms, and the arm mechanisms moves and positions the material delivery heads relative to the interior mandrel surface so that composite material is delivered directly to the outside mold line on the interior mandrel surface.
