Aeronautical structures are susceptible to vibrations that can become aggravated by aeroelastic phenomena. Therefore, methodologies for suppressing undesired aeroelastic responses are important for aeronautics. One of the new technologies, which are becoming more common involve the concept of smart structures. Among the promising materials for use in smart structures are the fluids that present rheological variations. These smart fluids in the presence of electric or magnetic field change their rheological properties very fast allowing applications in aeroelastic control. The main objective of this work is to present the viability of this fluid for future application in aeroelastic control. A flutter analysis using the PK method to show the effect of smart fluids to prevent the occurrence of flutter is presented.
