On the Aerodynamics of Birds

WebBirds appear to use their tails during flight, but until recently the aerodynamic role that tails fulfil was largely unknown. In recent years delta-wing theory, devised to predict the aerodynamics of high-perform-ance aircraft, has been applied to the tails of birds and has been successful in providing a model for the aerodynamics of a bird's tail. WebFlapping-wing micro air vehicles (FWMAVs) have the capability of performing various flight modes like birds and insects. Therefore, it is necessary to understand the various flight modes of FWMAVs in order to fully utilize the capability of the vehicle. The unique flight modes of FWMAVs can be studied through the trajectory optimization. This paper … WebOn the Aerodynamics of Birds' Tails.
