What can be learned from bird's lack of a fin for mini-airplanes

Abstract

Flight mechanical functions for which a fin is used are considered for small flying objects. One is to provide a sufficient level of static and dynamic yaw stability. It is shown that the required aerodynamic yawing moment capability decreases with a reduction in size. Thus, a wing of appropriate form can provide the necessary stability level. Another function is yaw damping. Here, the required aerodynamic moment is also reduced for smaller flying objects so that the wing can generate the necessary damping level. Further functions concern control and trim in asymmetric flight. It is sown that there are control possibilities for coping with such flight conditions without the need for a fin.
