The low Reynolds number aerodynamics of low-aspect-ratio wings for Micro Air Vehicles applications was numerically investigated. The viscous flows around MAVs wings with different aspect ratio (0.5, 1 and 2) were simulated by solving incompressible Navier-Stokes equations. The influence of aspect ratio and camber was analyzed in detail. Further results showed the different flow structures for those wings with different camber.
