Previous issue date: 2014-10-24 === A acelera??o das mudan?as tecnol?gicas e o processo de globaliza??o t?m intensificado a
competi??o e a necessidade de novos produtos (bens e servi?os), resultando na crescente
preocupa??o das organiza??es no desenvolvimento de avan?os tecnol?gicos, econ?micos e
sociais. O presente trabalho objetiva apresentar um panorama global do desenvolvimento das
tecnologias relacionadas ? energia e?lica e projetar suas tend?ncias. Para conduzir esta
pesquisa, faz-se (i) a revis?o bibliogr?fica sobre inova??o tecnol?gica, m?todos de prospec??o
tecnol?gica e fundamentos da energia e?lica; (ii) a an?lise de patentes, apresentando o
panorama atual da tecnologia estudada, por meio da busca de informa??es em bancos de
patentes; e (iii) a elabora??o do mapa da evolu??o tecnol?gica dos aerogeradores e constru??o
da tend?ncia futura a partir de informa??es da literatura e not?cias do setor estudado. A etapa
(ii) permitiu o estudo de 25.644 patentes entre os anos 2003 a 2012, no qual os EUA e China
lideram o ranking de depositantes e a empresa americana General Electric e a japonesa
Mitsubishi apresentam-se como os maiores detentores da tecnologia e?lica. A etapa (iii)
analisou e identificou que a maioria das inova??es apresentadas na evolu??o tecnol?gica da
energia e?lica s?o inova??es incrementais de produto para o mercado. A proposta de
tend?ncias futuras mostra que os aerogeradores do futuro tendem a ser de eixo horizontal,
s?ncrono, com a nacele mais alta que 194m e de di?metro do rotor superior a 164m, possuindo
gera??o superior a 7,5MW. Os materiais utilizados nas p?s ser?o novos materiais com
caracter?sticas de baixa densidade e alta resist?ncia. As torres est?o com tend?ncia h?brida de
materiais, aliando o a?o ao concreto. Essa disserta??o busca cobrir a lacuna existente na
academia sobre a utiliza??o de t?cnicas de prospec??o tecnol?gica para o setor de energia
e?lica, por meio do reconhecimento de que utilizar-se da an?lise de patentes, an?lise de
artigos cient?ficos e not?cias da ?rea, proporcionam conhecimento sobre o setor e que
influencia na qualidade das decis?es de investimento em P&D e, consequentemente, a
melhora da efici?ncia e efic?cia da gera??o de energia e?lica === The acceleration of technological change and the process of globalization has intensified
competition and the need for new products (goods and services), resulting in growing concern
for organizations in the development of technological, economic and social advances. This
work presents an overview of the development of wind energy-related technologies and
design trends. To conduct this research, it is (i) a literature review on technological
innovation, technological forecasting methods and fundamentals of wind power; (ii) the
analysis of patents, with the current technology landscape studied by means of finding
information in patent databases; and (iii) the preparation of the map of technological
development and construction of wind turbines of the future trend information from the
literature and news from the sector studied. Step (ii) allowed the study of 25 644 patents
between the years 2003-2012, in which the US and China lead the ranking of depositors and
the American company General Electric and the Japanese Mitsubishi stand as the largest
holder of wind technology. Step (iii) analyzed and identified that most of the innovations
presented in the technological evolution of wind power are incremental product innovations to
market. The proposed future trends shows that the future wind turbines tend to have a
horizontal synchronous shaft, which with the highest diameter of 194m and 164m rotor
nacelle top, the top having 7,5MW generation. The materials used for the blades are new
materials with characteristics of low density and high strength. The towers are trend with
hybrid materials, uniting the steel to the concrete. This work tries to cover the existing gap in
the gym on the use of technological forecasting techniques for the wind energy industry,
through the recognition that utilize the patent analysis, analysis of scientific articles and
stories of the area, provide knowledge about the industry and influencing the quality of
investment decisions in R & D and hence improves the efficiency and effectiveness of wind
power generation
