Abstract

In this paper an alternative design for variable sweep wings is investigated. It consists of a two-spar, CFRP (carbon fibres reinforced plastics) wing, with truss-like ribs. The spar-web is a shell structure laminated using an unsymmetric stack sequence in order to take advantage of the residual stress field developed during the curing process, resulting in increased transverse curvature of the spar. The effect of this curvature is twofold: to increase the moment of inertia to withstand bending stresses and, under certain loading conditions, to behave like an elastic hinge to allow the sweep angle of the wing to change.
