【 摘 要 】

For a stable flight, it is required adequate stability of the aircraft to have good conditions of navigability. The wing dihedral angle, the format, the position and the amount of wings are factors affecting the lateral stability of any aircraft (small or large). The purpose of this paper is study the applicability of dihedral wings in aircrafts, simulating the applications in a small aircraft. Thus, through theoretical final analysis, we can observe the use of dihedral angle implies some viability and it is going to bring significant improvement in performance and stability of the aircraft during the flight. The parameters used in this study were based on the project of a cargo radio controlled aircraft designed by Urutau Aero design, Research and Competition team, to the SAE Brazil Aero design Competition in which engineering students must design a robust and light cargo radio controlled aircraft.
