Wings have a function of changing the air flowing into force lift, and drag. It can reduce the drag is fairing flap track, where its function can reduce the obstacles caused by the effects of compressibility, fairing flap track also has a major influence on reducing the coefficient drag on airfoil. In this study, we observed the addition of fairing flap track to airfoil, fairing inspired by Sailfish and Blue Shark fish, its fins known to have speeds of 60 km/h. The independent variable in this research is compare airfoil NACA 4412 and NACA 6412, while the dependent variable is influence of fairing flap track configuration on unmanned aerial vehicle (UAV) character by knowing coefficient lift, coefficient drag and lift to drag ratio using software computational fluid dynamic (CFD). Simulation results know that the coefficient drag airfoil NACA 4412 decreased 0.3%, coefficient lift decreased 0.5% and coefficient drag airfoil NACA 6412 also decreased 0.4%, coefficient lift decreased 0.7%. It can be concluded that the addition of fairing on airfoil is very influential in reducing the value of coefficient drag and improve the coefficient lift on airfoil.
