摘要：
Fixed-wing micro air vehicle (MAV) is numerically investigated and optimized with genetic algorithm (GA). Aerodynamic performance evaluation is provided by three-dimensional incompressible Navier-Stokes equations that are solved numerically with artificial compressibility method. Present GA is real-coded and is developed with elite production, tournament selection, adaptive crossover and mutation. Five design points, angles of attack ranging from 2 deg. to 10 deg. with interval of 2.0, are considered. As a result, higher searching efficiency and more than 30% improvement in lift-drag ratio are obtained for every design point. Conclusively, optimal airfoils have three main characteristics: 1) elliptical planform, 2) AR of 1.2, 3) large leading-edge radius and cusped trailing-edge. This shape yields higher lift coefficient and decreases induced drag greatly, so the performance of MAV wing is improved highly at low Reynolds number.
