Séminaire de restitution EMMAV

Le 20 février 2013

EMMAV is a multi-disciplinary project which aims at promoting new intelligent electroactive materials as applied to micro- and nano- air vehicles (MAV & NAV). The use of new modelling approaches in fluid-structure interaction and of new experimental approaches, has been retained to build a micro-air vehicle demonstrator controlled by electroactive devices. The principal objective of the project is the optimisation of micro air vehicles performances in realistic environment, by means of electroactive morphing concepts. The new challenges of micro- and nano-air vehicles require, at an upstream research phase, the electroactive concept for an optimum design and control. This project aims at associating complementary scientific skills to design and develop Unmanned Air Vehicle (UAV) demonstrators including a mini-UAV equipped with piezo-actuators to perform optimal wing morphing to increase aerodynamic effiency and energy consumption performances. Furthermore, electroactive morphing surfaces will be used to achieve the flight control of a nano-air vehicle. Electroactive morphing will be applied to nano-rotors to increase the figure of merit through adaptive cyclic blade twisting. UAV demonstrators will be designed on the basis of fluid-structure modelling and of advanced experiments, both taking into account the properties of electroactive materials.
