The reduction of scale has made all the knowledge we known to face a new aspect. Designing a MAV has become a new challenge, which includes low Reynolds-number aerodynamics analysis, effective propulsion system design, effective power system design, selection of light-weighted sensor, and selection of light-weighted communication-navigation components. Every design phase is closely connected to each other. MAV can be divided into two configurations, one is fixed-wing and the other is flapping-wing. This experiment focuses on flapping-wing configuration. A four-bar linkage flapping mechanism was designed and constructed to simulate the flapping motion of a bird. The flapping mechanism was mounted on a 3-DOF, high-frequency-response force-balance in order to measure the dynamic change of lift and drag situation. The experiment result shows that the increasing of flapping frequency for 30cm-span flapping model can produce 2-8 times more lift than can be accounted for by conventional (no flapping)flight. Using by phase average method let me clearly understand that the effective lift produced is during the down-stroke of flapping motion and the result of flow visualization show us that the effective lift produced rely on the interaction of a leading-edge vortex(created by dynamic stall during flapping) and wing-tip vortex .

MAV can be divided into two configurations, one is fixed-wing and the other is flapping-wing. This experiment focuses on flapping-wing configuration. A four-bar linkage flapping mechanism was designed and constructed to simulate the flapping motion of a bird. The flapping mechanism was mounted on a 3-DOF, high-frequency-response force-balance in order to measure the dynamic change of lift and drag situation. The experiment result shows that the increasing of flapping frequency for 30cm-span flapping model can produce 2-8 times more lift than can be accounted for by conventional (no flapping)flight. Using by phase average method let me clearly understand that the effective lift produced is during the down-stroke of flapping motion and the result of flow visualization show us that the effective lift produced rely on the interaction of a leading-edge vortex(created by dynamic stall during flapping) and wing-tip vortex .
