Resumo
A aeroelasticidade é uma importante área da ciência que estuda as interações entre forças estruturais e aerodinâmicas. Além de estudos teóricos, envolve trabalhos experimentais, que se mostram como ferramentas ideais para verificação, validação e aprofundamento dos estudos envolvendo a aeroelasticidade. Dessa maneira, o presente trabalho compreende o projeto, o desenvolvimento, a construção e os ensaios realizados em um aparato aeroelástico com perfil NACA0012, com uma superfície de controle e compensador instalados em seu bordo de fuga. As peças do aparato são fabricadas por meio de processos de impressão 3D, são montadas e passam por processo de acabamento pós-impressão. A instrumentação do aparato é composta de equipamentos de baixo custo, como potenciômetros para registro dos movimentos do modelo. Diferentes configurações são consideradas, inclusive variando o ângulo de ataque e a velocidade de escoamento. Campanhas de ensaios são realizadas em túnel de vento e os sinais de respostas são analisados e discutidos.
Aeroelasticity is an important area of science that studies the interactions between structural and aerodynamic forces. In addition to theoretical studies, it involves experimental work, which prove to be ideal tools for verification, validation and deepening of studies involving aeroelasticity. In this way, the present work comprises the design, development, construction and tests carried out on an aeroelastic apparatus with NACA0012 airfoil, with a control surface and compensator installed on its trailing edge. The parts of the apparatus are manufactured through 3D printing processes, are assembled and undergo a post-print finishing process. The instrumentation of the apparatus is composed of low-cost equipment, such as potentiometers for recording the model's movements. Different configurations are considered, including varying the angle of attack and the flow velocity. Rehearsal campaigns are carried out in a wind tunnel and the response signals are analyzed and discussed.
