Abstract –The Unmanned Aerial Vehicle (UAV) having no pilots have proven their values in many areas. In this research we have made an attempt design and analyze an indigenous UAV with good stability knowing the mass of the entire system. Stability analysis of the UAV has been carried out at different conditions and the values are noted. The paper will also discuss the step by step procedure of design and analysis of the complete UAV. The design of the vehicle has been done in catia V5 and the analysis has been carried

out in XFLR software. The software structure of the UAV has been

designed in such a manner to give good lift even at very low speed. this UAV has got the special ability to operate even at low Reynolds number. The results of this analysis could be utilized to further improve the aerodynamics of the existing design and enhance the stability and

The term UAV is an abbreviated of unmanned aerial vehicle which mean aerial vehicle which operate

without a human pilot. UAVs are commonly used in boththe military and police forces in situations where the risk of sending a human piloted aircraft is unacceptable or the situation making using an unmanned aircraft impractical. The small unmanned aircraft are designed
