内容記述 | Flapping motion consists of combined motions of wing reciprocation and rotation, and thus generates complex flow field and pressure change around the wing, which produce typical sound sources such as dipole or quadrupole sources. This implies the control of flapping sound is an important issue to realize practical flapping wing air vehicles. For this purpose, we developed a numerical scheme to analyze sound generation and transmission of flapping wing by combining CFD and acoustic analyses. This scheme is applied to two types of motions, i.e. hovering and forward moving motion of insect (hawkmoth). Conspicuous similarity is found in both flying types, i.e. the dominance of fundamental frequency wave in front and the second or higher harmonic wave in side or bottom. Another similarity is found in the sound directivity, i.e. the strong sound transmission in the direction perpendicular to the flapping plane and the weak transmission in the direction parallel to the flapping plane. These results clearly represent the relationship between wing motion and sound characteristics, and thus providing us with insights on the control methods of flapping sound. | |||||
