ABSTRACT

Unmanned Aerial Vehicle is a type of aircraft that has a very wide application. In this study, numerical calculations were performed using ANSYS Fluent software to find the configuration and dihedral angles that were considered to provide the best lift, drag, and moment pitch values. The study was conducted by varying two-tail configurations with high and low specifications with each having three variations in the dihedral angle values. Each variation has the same stabilizer surface area value. The study was conducted using the k-omega SST turbulence model (k-ω SST) with the mission profile having a distance of 200 km, a height of 500 m, and a speed of 20.83 m/s. Mesh is made of polyhedral with quality skewness and mesh orthogonal very good. The results of this study indicate that unmanned aircraft with a low tail configuration with the smallest dihedral angle produces the biggest lift and pitch moment value. The drag value produced by each variation has a very small difference that can be ignored.
