Projeto estrutural da asa da aeronave da equipe Abutres Aerodesign

Abstract

The Society of Automotive Engineers (SAE) airplane design competition annually challenges several teams from universities throughout Brazil to design aircraft. Among the steps included in the conception of a new aircraft, the structural design has great relevance. In the competi- tion, one of the fundamental objectives is to lift the maximum load with the lightest aircraft possible, thus maximizing the points obtained in the competition. In this way, this work aims to accomplish the structural design of the wing of an aircraft of the Abutres Aerodesign team. The structural project involves from the survey of the loads acting on the structure during its entire mission, from the aircraft take-off, flight and landing, to the subsequent structural design, prototyping of the model and validation of the project. The work is sequenced to show the calculation of the main stresses involved in the wing structure, material selection for construc- tion, and a static and buckling analysis using the Finite Element Method (FEM) to ascertain the structural integrity of the wing throughout the aircraft mission. The results obtained show that the aircraft designed for the competition has safety margins above the minimum proposed in aeronautical standards, making the project safe for the competition.
