The insect-like flapping flight has inspired the development of small-sized, power-efficient,
and highly maneuverable micro air vehicles (MAVs) capable of indoor flight and hovering
in a low-speed flight environment. An efficient design of flapping wing MAV requires a
crucial wing design since the flapping wing will be responsible for lift, propulsion, and
maneuvers. The interaction between unsteady aerodynamics and structural flexibility
plays a vital role in the efficient design of flapping wing MAVs since it can lead to the
control system’s failure through strong nonlinear interactions. Therefore, the thorough
study of the widely different vortex patterns and their interactions generated in the wake
of the flexible flapping wing with different kinematic parameters is essential.
The proposed study focuses on exploring the dynamical fluid-structure interaction
behavior of flexible (chord-wise flexibility) foil. This study seeks to identify the key
parameters and physical mechanisms in the range of natural responses of the flexible foil
fluid-structure interaction. The works described above portray a clear picture of how
oscillatory body kinematics affect near-body flow and wake characteristics and resultant
forcing on the body.
