Micro aerial vehicles (MAVs) have had a recent surge of interest due to their many commercial, military and scientific applications. Their wide range of uses, such as those intended for close proximity situations, could include search and rescue missions as well as reconnaissance and surveillance.The optimal Strouhal numbers, that is the dimensionless number describing oscillating flow mechanisms, obtained for a freely flying system are found to be in the range of 0.2≤ St≤ 0.35[5]. It has been proposed that Strouhal number selection in natural flight is not the result of an active feed back control mechanism but a limit cycle …
