Among the passive and active methods used to attenuate or suppress aeroelastic phenomena, we highlight the use of SMA. In this context, this research aims to analyze the flutter response of a flexible wing of high aspect ratio, through the use of activated SMA wires. For this, a research model was designed and the actuators were incorporated into it. The results showed reductions in the FRF peaks up to 86% and an increase up to 28% in the critical flutter speed
