A utilizacao de aerogerador esta em plena expansao e as pesquisas no campo aerodinâmico sao fundamentais, uma vez que a aplicacao de tuneis de vento e uma pratica bastante eficaz no projeto de pas. O tunel de vento e um equipamento utilizado em testes aerodinâmicos para verificar a eficiencia, resistencia ou capacidade de uma parte ou mesmo de um todo sem a necessidade de haver movimento dos objetos, apenas o vento percorre a secao de testes e atinge o modelo. Sabe-se que a aplicacao de tuneis de vento em laboratorios de projeto para ensaio de sistemas aerodinâmicos e um recurso muito eficaz nas pesquisas e testes dos prototipos de pas e aerogeradores, pois ensaiar prototipos nas condicoes de vento ao ar livre nao e muito eficaz, pelo fato de depender das condicoes climaticas e da velocidade do vento local que nao e constante, dificultando o monitoramento e coleta de informacoes para determinar a eficiencia de um prototipo. Esta pesquisa apresenta o desenvolvimento do projeto mecânico de um tunel de vento, visando desenvolver tecnologia na area de aerogeradores, bem como para realizar testes aerodinâmicos.

ABSTRACT The use of wind turbine is in full expansion and research in the aerodynamic field is fundamental, since the application of wind tunnels is a very effective practice in the design of blades. The wind tunnel is an equipment used in aerodynamic tests to check the efficiency, strength or capacity of a part or even a whole without the need for movement of the objects, only the wind travels through the test section and reaches the model. It is known that the application of wind tunnels in aerodynamic systems testing laboratories is a very effective resource in the research and testing of blade and wind turbine prototypes, because testing prototypes in open-air wind conditions is not very effective, because it depends on weather conditions and local wind velocity that is not constant, making it difficult to monitor and collect information to determine the efficiency of a prototype. This research presents the development of the mechanical design of a wind tunnel, aiming to develop technology in the field of aerogenerators, as well as to perform aerodynamic tests. Keywords: Wind turbine. Blades. Prototype. Sizing.
