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