Tow-steered composites are optimized for use in tailoring the aeroelastic behavior of a simple two-dimensional composite wing, with particular emphasis on improving both flutter/divergence airspeeds and gust loads. Symmetric layups are considered where the fibers vary in orientation along the wingspan and chord. Tow-steered laminates were found to increase the instability airspeed by up to 7% compared with optimized straight-fiber laminates and by 13% compared with optimized laminates with standard (0/±45/90 deg) plies. Tow-steered laminates were also found to reduce the peak wing root gust loads (up to 52%) and the correlated gust loads (up to 24%). The lowest gust loads were reached with higher order nonlinear fiber angle variations when either all plies were optimized or when two-dimensional fiber angle variations were used. Optimization strategies that allowed the fiber angles to vary freely in each ply generally performed better than optimizations based on the rotation of (0/±45/90 deg)-ply stacks along the span of the wing.
