Abstract

In this paper we consider the various methods employed by birds to generate lift and control it. We focus on three particular aspects, namely the method that a bird employs to compensate the transport lags, the method of rapid lift generation employed and growth of lift to a steady value and finally the angle of attack at which a bird flies to generate maximum lift. Based on the study of these methods we establish mathematical control models for compensating the transport lags, and establish a constraint for the aeroelastic tailoring of a wing to maintain a steady angle of attack even when flexible modes of vibration are present. Finally the unsteady aerodynamic modeling of vortex flows for active control applications is discussed.
