An airfoil for a micro air vehicle that includes components enabling the
airfoil to adjust the angle of attack (AOA) of the airfoil in response to
wind gusts, thereby enabling the airfoil to provide smooth flight. The
airfoil may include a first compliant region positioned between an
inboard section and a first outboard section and may include a second
compliant region between a second outboard section and the inboard
section. The compliant regions enable the first and second outboard
sections to bend about a leading edge section and move relative to an
inboard section. This action creates smoother flight due to numerous
aerodynamic advantages such as a change in the angle of attack and
improved wind gust rejection due to adaptive washout as a result of the
airfoil flexing, twisting and decambering.
