A full scale morphing wing tip demonstrator with a droop-nose adaptive morphing wingtip was wind tunnel tested as part of the European FP7 project NOVEMOR. This demonstrator features a flexible fiberglass skin and an aluminium internal compliant mechanism. The tests were carried out to assess the performance of compliant mechanism and skin under aerodynamic loading. The results show that strains in the mechanism are mainly from the actuation showing adequate stiffness in the mechanism. In addition to strains, pressure data was taken to determine aerodynamic loading. The Finite element and computational fluid dynamics simulations performed showed good agreement with the experimental values.
