We study the influence of wing geometry on the aerodynamic performance of micro aerial vehicles (MAVs). Four different wing planforms: rectangular, Zimmerman, inverse Zimmerman, and elliptical are considered. The inverse-Zimmerman planform have a slightly better performance. The peak of aerodynamic performance moves to lower angles of attacks as the aspect ratio of the wing is increased. The influence of the edge-shape of the wing on the aerodynamic coefficients is also studied. We find that moderate edge-ratio of 2 or 3 produces the lowest drag coefficients. Changing the side-edge geometry influences the lift coefficients but not the drag coefficients.
