BA609 wing skins are continuous from tip to tip and extend from approximately 5% to 50% of wing chord. They are constructed of C/EP prepreg unidirectional and fabric material with cocured hollow tip-to-tip hat-shaped stringers. The skins are tooled to the IML surface to provide the consistent hat stringer locations necessary for subsequent bonding of rib components. Caul plates are used to control the OML aerodynamic surface. Elastomeric mandrels vented to the autoclave provide pressure to the stringer laminates during cure. Each hat stringer consists of one inboard and two outboard segments. The stringer segments are fabricated off line on male mandrels and assembled onto the skin IML bond tool. The basic skin consists of plain weave fabric and unidirectional 6-inch-wide tape. A major producibility consideration for the BA609 wing skin was the desire to minimize cycle time under the tape laying machine. This goal was accomplished by designing the skins so that most manually placed ply details are produced off line and then placed on the tool prior to or after all ATLM operations have been completed. This paper will provide an overview of the BA609 torque box skin design, tooling approach, and manufacturing approach.
