Projeto de uma bancada para testes de motores classe sae aerodesign

Abstract

Extension is one of the pillars they support the undergraduate universities, alongside teaching and research. In order to seek to solve existing problems of interest and need to society, they are directly involved in training, scientific production, dissemination of information and technology. In view of this context, the SAE Aerodesign project, which is widespread in Brazilian universities, is inserted, students work in the conception, design, manufacture and tests of a radio controlled aircraft that must take off, land and perfectly meet the mission requirements. One of the fundamental stages of the project is a quantitative selection of the most suitable powertrain, for this it is important to collect the thrust and power data provided by the engine and propeller assembly on a test bench. However, in the reality of universities, a large part of the engine test benches are technologically out of date and the works that address the design of the test benches do not present the results that will facilitate their implementation. As a result, the present work has a SAE Aerodesign class engine test bench project, proposing a more assertive design methodology, based on the selection of the best test bench configuration and the dimensioning of components from the perspective of their modes possible failure. The choice of the test bench configuration was due to a literature review and the study of the needs of the IFPI Sol do Equador Aerodesign project. The design was duly justified and formulated by the concepts of mechanics of solids, fatigue, machine elements and mechanical vibrations. As a dimensioning resource, the results are met in the form of design curves for each component, which make reproducibility feasible and support the decision making regarding adaptations. Finally, a realistic model of the parts and assembly was built, facilitating the later design of the project. Thus, the contribution to the modernization of Aerodesign do Brasil projects was evident.
