Proceedings of the World Congress on Engineering 2015 Vol II WCE 2015, July 1 - 3, 2015, London, U.K. The Study and Analysis of Using Wing Dihedral on the Side of an Aircraft’s Static Stability Erika R. S. Teixeira, Beatrice Harumy de F. Yokota, Dilermando Ferreira Neto, Paulo André M. Pimentel, Sahmira Paula Santos dos Santos, Luciana Barbosa dos Santos, Antônio Claudio Kieling Abstract - For a stable flight, it is required adequate about and understanding the stability area, the main issues stability of the aircraft to have good conditions of about stability during the process of preparing of the design of navigability. The wing dihedral angle, the format, the a small aircraft will be discussed. Its applicability will also be position and the amount of wings are factors affecting the explained by relating the study of stability with the lateral stability of any aircraft (small or large). The construction of an airplane model intended to participate in the purpose of this paper is study the applicability of dihedral SAE Brazil Aerodesign Competition. wings in aircrafts, simulating the applications in a small In large or small aircrafts, the study of stability is essential for aircraft. Thus, through theoretical analysis, we can the proper functioning of it. According to Anderson Jr. [1], observe the use of dihedral angle implies some viability even if a plane is designed carefully to have the aerodynamic and it is going to bring significant improvement in
