In this paper, the research performed on flexible-wing Micro Air Vehicle (MAV) is described. Flexible-wing MAV is renowned for improved lift characteristics and smooth flight in gusty conditions than its rigid-wing counterpart. The wind-tunnel experiments are carried out for various configurations to determine the ways of further enhancing lift. The effects of following techniques are quantized: (1) underlying skeleton; (2) wing membrane extension; (3) wing membrane relaxation and (4) wing membrane material. The results are compared with the rigid-wing. The baseline geometric description for all MAVs includes 15 cm box dimension and aspect ratio of 1. Results show that the skeleton layout significantly governs the lift characteristics. Latex sheets are found to be the best choice for membrane material. The effect of membrane extension and relaxation proved to be of little advantage. The aerodynamic assessment at low Reynolds number has demonstrated significant improvement of lift characteristics for flexible wings over rigid wings counterpart.
