Just under this background, studying on the flight mechanism of flapping-wing MAV and sample fabrication from the bionics are conducted in this dissertation. The kinematics equations of insect wings can be acquired by the observation and measurement on the natural insect in researching paper. The geometry model of insect is established by UG technology. The three dimensional grid during the insect moving in the flow field is achieved which adopted grid generation method. The characteristic of lift and drag are attained by simulation the surround flow field during the locomotion of wings, and the flight mechanism of insect is discussed. Based on this study, the physical flapping-wing MAV is fabricated by the acquirable materials and parts of apparatus in existence.
