Gradient-based optimisation of composite wings requires high-fidelity analysis, but 2D/3D FEM is prohibitive for large design spaces. We propose 1D Carrera Unified Formulation (CUF), adjoint sensitivities in reverse-mode for ply sizing. On Z-stringer panel, CUF with Taylor expansion matches 3D strains within 5% at 1-2 orders of magnitude lower cost. Scalable to DLR wing-box benchmark.
