- Influence of wing shapes of a pair of flapping wing inspired by small insect
抄録
<p>The small insect, especially the Diptera (for example, fly, mosquito and so on) has a pair of wing and can fly with high mobility and high efficiency. Hence, by consulting the flapping flight of Diptera, it will develop the small flight device which has high flight performance. We focused the planer shape of wing. Then the rectangular wing model whose aspect ratio is agree with that of Diptera wing was treated as the standard model and create some wing model. To study the aerodynamic feature, we performed the numerical simulation of flow around flapping wing by using ANSYS CFX. Then the behavior of the wing model was treated as the immersed boundary by using the “Immersed Solid” function. As results, the following became clear. The average lift force during half stroke is proportional to the squared flapping frequency and the wing area. When the two rectangular wings which have the same wing area were compared the average lift force, the long span wing is higher than the long cord wing. Comparing the mosquito like wing model (Real0) and the rectangle wing (Rect0) which has same cord and span with the Real0, the average Lift and thrust forces per wing area during half stroke were almost same value when the attachment angle of wing model was changed 0 to 60 degrees. Hence, the Real0 has more efficient than the Rect0 from the viewpoint of the generated force per unit area.</p>
