Elastomer-Based Skin for Seamless Morphing of Adaptive Wings

Elastomeric materials are developed for adaptive wings focusing on the elasticity at minus 55 °C to ensure morphing at cruise altitudes. In order to optimize fatigue and ageing properties of this new multi-material device, FEM simulations and mechanical tests are carried out. Two large skin panels are finally manufactured and successfully assembled into a true-scale wind tunnel demonstrator for the experimental validation of adaptive trailing edge device functionality in simulated operative conditions.
