Abstract. This paper describes a novel flapping wing micro air vehicle
(FWMAV),which can achieve two active degree of freedom (DOF) movements of
flapping and swing, as well as twisting passively. This aircraft has a
special “0” figure wingtip motion trajectory with the 140∘
flapping stroke angle. With these characteristics integrated into the simple
flapping mechanism, the aerodynamic force is somewhat improved. The model
made a balance between the improved aerodynamic performance induced by
complicated movements and the increased weight of the extra components in
aircraft. In the driven design, Only one micro-motor is employed to drive
the wing flapping and swing motion simultaneously forming the prescribed
trajectory. The 23 g aircraft could reach the maximum flapping frequency
of 11 Hz with the tip-to-tip wingspan of 29 cm.
