Simulation of winglet with bend angles of 45, 60 and 90 degree

Abstract

UAV (Unmanned Aerial Vehicle) is an unmanned aircraft or also called a military drone with long range coverage because it can air on a matter of days. One development that continues to stand out is the BWB type UAV where, the angle of wing bending varies. This research is for simulation of wing angle bend between 45, 60 and 90 degrees. The method used in the simulation uses the Finite Element Method with the help of ANSYS 17.0. Haisl's research shows that at an angle of 45 degrees the airflow within the wing is fairly normal and evenly distributed. The pressure on the BMB also increases with the addition of the speed and angle of bend. On the results of the study also showed that the value of the lift is inversely proportional to the value of drag.
