Notes:
Morphing aircraft wings require flexible skins that can undergo large strains, have lowin-plane stiffness. In this paper, the sandwiched structure is designed to maintain airfoil shapethroughout transition and not to suffer from large out-of-plane deformation under aerodynamicpressure loads. It consists of honeycomb and flexible skin. Honeycomb which is high-strain capablein one direction without dimensional change in the perpendicular in-plane axis provides distributedsupport to the honeycomb. Flexible skin is used to create the smooth aerodynamic surface. Themorphing wing structure is developed together with the sandwiched skin technology. It is capable ofchanging in chordwise and increasing chord by 20%. Elastomeric and SMP skins are selected for use.Embedded heating wire springs act as the activation system for the SMP. Experiment results show themorphing wing model with elastomeric or SMP skins can be driven successfully by DC motor
