Body Accelerations During the Wingbeat in Six Bat Species: The Function of the Upstroke in Thrust Generation
The kinematics and aerodynamics of Rhinolophus ferrumequinum, R. hipposideros, Myotis nattereri, M. mystacinus, Plecotus auritus and Eptesicus serotinus in horizontal flight at various flight speeds are described. Three kinematic patterns can be recognized. At low speeds M. nattereri, M. mystacinus...
