Unsteady Stalling Characteristics of Flapping Wing Micro Aerial Vehicle 2006-01-2406

There is a serious effort to design aircraft that are as small as possible for special, limited-duration military and civil missions. These aircraft, called micro air vehicles (MAVs), are of interest because electronic surveillance and detection sensor equipment can now be miniaturized so that the entire payload mass is less than 18g. The current goal is to develop aircraft with a 15cm maximum dimension that have a mass of less than 90 g. The present study focuses on unsteady stalling characteristics of a flapping flight for different plan form models. The computational study was carried out by using FLUENT package. The results were verified with experimental values. Experiments were carried out in an open jet tabletop tunnel having test section of 350×350 mm and velocity range up to 10 m/s. Flapping actuation was generated by a newly developed rack and gear mechanism. A strain-gauge type load cell was used to measure the lift force. The wings of various cambered shape have been fabricated using Carbon composites as spars and Mylar sheet as a skin. Skins are attached to the skeleton part of the wings by using super glue bond.
