Aerodynamic Performance of a Passive Pitching Model on Bionic Flapping Wing Micro Air Vehicles

Figure 1

Geometric parameters of a flapping wing. is the unilateral wingspan, is the mean chord length, is the distance between the leading edge and the rotation axis, is the radius of the wing tip, is the distance between the wing root and the flapping axis, and is the radius of the second moment of the wing area.
