Abstract

Pá DE ROTOR PARA GERADORES EóLICOS COM SEUS áNGULOS DIEDROS VARIANDO DE MODO DISCRETO E OU CONTINUO AO LONGO DA MESMA. Refere-se a uma pá para rotores de geradores eólicos com ângulos diedros variando de modo discreto e ou contínuo com a finalidade de aumentar as eficiências aerodinâmica e estrutural da mesma reduzindo tanto as forças de arrasto induzido como os momentos fletores agentes em sua estrutura permitindo assim o projeto e construção de rotores com menor peso e maior potência de vento absorvida, quando comparados a rotores de mesmo diâmetro e número de pás semelhantes, mas sem estes ângulos diedros.
