    Trade-off of lifting and propulsion capacity of tandem flap**-fixed airfoils by inclining the stroke plane

    A tandem flap**-fixed airfoil configuration with a narrow gap can be found in insects and micro air vehicles (MAVs). Compared to a single flap** airfoil, the interaction between the two airfoils can bring ...

    Volumetric measurement and vorticity dynamics of leading-edge vortex formation on a revolving wing

    Leading-edge vortex (LEV) is a hallmark of insect flight that forms and remains stably attached on high angle-of-attack (AoA), low aspect ratio (AR) wings undergoing revolving or flap** motion. Despite the e...

    Effects of kinematics on aerodynamic periodicity for a periodically plunging airfoil

    In conventional Micro-Air-Vehicle design inspired by insects, the periodical motion of flap** airfoil usually leads to generation of a periodical aerodynamic force. However, recent studies indicate that time...
