AB  - This paper presents a numerical investigation on the potential for unsteady aerodynamiccontrol on integrally-actuated membrane wings made of dielectric elastomers (DEs). Theycombine the advantages of membrane shape adaptability, which produces increased lift anddelayed stall, with the benefits of simple, lightweight but high-authority control mechanismoffered by integral actuation. High-fidelity numerical models have been developed to predicttheir performance and include a fluid solver based on the direct numerical integrationof the unsteady Navier-Stokes equations, an electromechanical constitutive material modeland a non-linear three-dimensional membrane structural model. Numerical results showthat harmonic actuation of 5.0 kV gives an overall increase in the aerodynamic efficiencya fixed wing configuration the wing of up to 6.0%, measured as the lift-to-drag ratio. Inaddition, the definition of a reduced order model based on POD modes of the completehigh-fidelity system allows the synthesis of a feedback control system to obtain on-demandaerodynamic performance.
