In this paper a number of control surfaces method for UAV performance optimization was objected. An unmanned aerial vehicle is a type of aircraft that operates without any human intervention. Unmanned aerial vehicles are used in many industries and applications, including communications, GIS, border surveillance, research and rescue, scientific and environmental studies, agriculture, as well as the military industries. The advantages of using drones include high efficiency, access to difficult and dangerous zones, cost reduction and human hoarding. However, the use of UAVs also comes with challenges and problems. One of the most important problems is the risk of losing control and running out of fuel and aerodynamic problems at different angles of attack or flow condition around the UAVs that change the performance and stability of UAVs. In this research, the samples are examined, Geometries and shapes changes created on the UAV’s wing to improve the aerodynamic coefficients in the low and high angle of attack, flight range and etc. in other words, this current research is to enhance the manoeuvrability of a UAV, performance and stability parameter and aerodynamics behaviour of UAV, a number passive flow control method was employed and studied
