Systems and methods for assembling a skin of a composite structure on an outer surface of an inner mold line layup mandrel. The systems and methods include receiving a plurality of ply kits, assembling the plurality of ply kits to form a skin segment that defines a portion of the skin, and affixing the skin segment to the outer surface of the layup mandrel. The assembling includes transferring a respective ply kit of the plurality of ply kits to a non-planar transfer tool, compacting the respective ply kit on the non-planar transfer tool, and repeating the transferring and the compacting for each ply kit in the plurality of ply kits to form the skin segment.

1. A system for assembling a composite structure, the system comprising: a supply of ply kits, wherein each ply kit in the supply of ply kits includes a plurality of plies of a composite material;a skin segment assembly system, wherein the skin segment assembly system includes:(i) a non-planar transfer tool that is configured to simultaneously support at least two ply kits from the supply of ply kits on a non-planar upward-facing surface thereof; and(ii) a compaction tool that is configured to compact the at least two ply kits on the non-planar transfer tool to form a skin segment; anda layup mandrel that is configured to receive the skin segment on an outer surface thereof. 2. The system of claim 1, wherein the non-planar transfer tool further includes at least one compaction bladder, wherein the compaction bladder is configured to be inflated to press the skin segment into contact with the outer surface of the layup mandrel. 3. The system of claim 1, wherein the skin segment assembly system further includes a planar indexing surface that is configured to support each of the at least two ply kits prior to the at least two ply kits being supported on the non-planar upward-facing surface of the non-planar transfer tool. 4. The system of claim 3, wherein the skin segment assembly system further includes a conveyance tool that is configured to transfer a respective ply kit of the at least two ply kits from the planar indexing surface to the non-planar upward-facing surface of the non-planar transfer tool. 5. The system of claim 4, wherein the conveyance tool is configured to bend the respective ply kit to a transfer radius of curvature that is less than a radius of curvature of the non-planar upward-facing surface of the non-planar transfer tool. 6. The system of claim 4, wherein the conveyance tool is configured to transfer a first ply kit of the at least two ply kits to the non-planar upward-facing surface of the non-planar transfer tool and to subsequently transfer a second ply kit of the at least two ply kits to the non-planar upward-facing surface of the non-planar transfer tool to form a stack of ply kits that includes at least the first ply kit and the second ply kit. 7. The system of claim 4, wherein the conveyance tool is configured to flip the respective ply kit of the at least two ply kits when the respective ply kit is transferred from the planar indexing surface to the non-planar upward-facing surface of the non-planar transfer tool. 8. The system of claim 7, wherein each ply kit in the supply of ply kits is operatively attached to a respective ply carrier sheet, further wherein the respective ply carrier sheet is configured to be removed from the ply kit during assembly of the skin segment. 9. The system of claim 8, wherein the respective ply carrier sheet is located between each ply kit in the supply of ply kits and the planar indexing surface when each ply kit in the supply of ply kits is located on the planar indexing surface. 10. The system of claim 9, wherein the conveyance tool is configured to flip the respective ply kit such that the respective ply kit is located between the respective ply carrier sheet and the non-planar transfer tool when the respective ply kit is located on the non-planar upward-facing surface of the non-planar transfer tool. 11. The system of claim 1, wherein the system further includes the composite structure, wherein the composite structure includes the skin segment and at least one stringer, and further wherein the skin segment is operatively attached to the at least one stringer. 12. The system of claim 1, wherein the compaction tool is a vacuum compaction tool. 13. The system of claim 1, wherein the non-planar upward-facing surface of the non-planar transfer tool is concave, and further wherein the layup mandrel is an inner mold line layup mandrel. 14. The system of claim 1, wherein the non-planar transfer tool further includes at least one shim that is configured to define at least a portion of a shape of the non-planar upward-facing surface thereof. 15. The system of claim 1, wherein the system includes the composite structure. 16. The system of claim 15, wherein the composite structure includes a plurality of skin segments. 17. The system of claim 15, wherein the composite structure includes at least one of an aircraft, a portion of an aircraft, an airframe, a portion of an airframe, a fuselage, a portion of a fuselage, a fuselage barrel, a portion of a fuselage barrel, a wing, a portion of a wing, a stabilizer, and a portion of a stabilizer. 18. The system of claim 1, wherein the outer surface of the layup mandrel defines a contour of an inner surface of at least one of an aircraft, a portion of an aircraft, an airframe, a portion of an airframe, a fuselage, a portion of a fuselage, a fuselage barrel, a portion of a fuselage barrel, a wing, a portion of a wing, a stabilizer, and a portion of a stabilizer. 19. The system of claim 1, wherein a shape of the non-planar upward-facing surface of the non-planar transfer tool corresponds to a shape of the outer surface of the layup mandrel. 20. The system of claim 1, wherein the layup mandrel is configured to be removed from the composite structure subsequent to formation of the composite structure.
