Micro-aerial vehicles (MAV) are being developed all round the world for a variety of civilian and military13; purposes. NAL has taken up a project to develop a fixed wing MAV of 300mm size weighing nearly 300gm13; capable of flying for 20-30 minutes in autonomous flight, with optical and transmission devices as payload. The13; aerodynamics of the MAV [1-3] having restricted span and flying at low Reynolds numbers is much different13; from that of a typical aircraft. These MAVs have a near circular wing planforms similar to the one designed by13; Zimmermann [4] and have a sharp leading edge and thin cambered sheet instead of a thick airfoil. Several such13; MAVs have been designed and successfully flown all over, however the flow over the MAVs wing is not well13; understood especially the mechanism of obtaining lift at high incidences. Further, established design procedures13; do not exist for MAV as for conventional aircrafts. Computation of such complicated low Reynolds number13; flows is rather difficult. Thus experimental studies are of utmost importance for not only understanding the flow13; but also to optimize the design.
