Abstract:

There exists a very rich variety of distinctive properties which are relevant to unsteady, nonlinear flows and structural dynamics, as the flexible structures and fluids are coupled dynamically. If the aeroelastic effects are controlled and utilized properly, the aerodynamic performances and self-adaptability of aircraft wings and wind turbine blades could be improved significantly. In this paper, the progress and major challenges in aeroelasticity and its applications in flow control are reviewed, and three main directions, including the aerodynamic characteristics of the membrane wing, the drag reduction technique using flexible wall and the Sinha disturbers, are discussed in detail. In particular, the relevant studies including the experimental techniques, the numerical methods for fluid-structure interactions and theoretical methods such as nonlinear dynamics, Lagrangian coherent structure are summarized, and the great potential of the aeroelasticity in flow control and its academic values are emphasized, in order to pave the way for the researchers who are engaged in this field.

Key words: aeroelasticity, flow control, membrane wing, flexible wall, Lagrangian coherent structure
