Abstract

The development of aerospace technology in the country is now getting faster with the existence of Unmanned Aircraft (PUNA) or known as Unmanned Aerial Vehicles (UAV) which are aircraft that fly without a pilot during flight. UAV is used in surveillance or monitoring where the UAV is given a camera to record an object that is used as monitoring data. In the process of designing an aircraft, it must have Design Requirements and Objects (DRO). This DRO will later be used as a reference whether the aircraft has reached DRO or not. Computational Fluid Dynamic (CFD) is a branch of fluid mechanics that uses numerical methods to solve and analyze problems involving fluid flow. By using the CFD approach, the aerodynamic characteristics of the aircraft are easier to obtain. So that the design process will be faster. However, the CFD results must be validated with the analytical results on the wing used. To determine the lift and drag forces used CFD simulation using ANSYS software. The results of the aerodynamic simulation at an angle of 0º maximum speed coefficient of lift obtained is 0.059 and coefficient of drag is 0.031. The maximum lift coefficient is obtained at an angle of 17º at the maximum speed condition, which is 0.349 and the coefficient drag maximum is 0.145.
