Electroactive Morphing is a multidisciplinary axis, combining aerodynamics, innovative materials and mechatronics. This concept consists in improving the aerodynamic performance by the use of actuators deforming the airfoil of an aircraft in real time. Supported by Airbus, the modeling, design and implementation of a small scale demonstrator is a first step. Based on an A320 wing profile, it is equipped with actuators for hybrid electroactive morphing: large deformations at low speeds by Shape Memory Alloys are associated with the integration at the trailing edge of piezoelectric actuators allowing high operating frequencies at lower amplitude. A second step of the thesis is dedicated to wind tunnel tests. The measurement of forces and the Particle Image Velocimetries allow for the understanding of the flow and turbulence physics. The study of this fluid-structure-actuator coupling presents the effects of the morphism by independent actuation; then the nonlinear coupling of the hybrid actuation. The third step is the transition to a realistic scale of actuators, by designing an "electro-morphed" macro-actuator. An optimization sizing approach is proposed. Based on new actuation technologies, a prototype of such a macro-actuator is then designed to be tested.
