This paper presents an estimate of the drag polar of the complete configuration of fixed-wing UAV using equivalent skin friction coefficient accounts for light aircraft derived for similar categories. Coefficients are derived from an aerodynamic analysis of UAV used for surveillance, reconnaissance, and artillery support in various civilian and military operations. The UAV’s parasitic drag is significantly influenced by the presence of miscellaneous components like nonretractable landing gears, motors and propellers on the tail-boom section or gimbal. These components are responsible for more than half of an UAV’s total parasitic drag. This calculation is used for the initial sizing of the UAV for a surveillance or reconnaissance mission.
