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.ROTOR BLADE FOR WIND GENERATORS WITH THEIR DIEDER ANGLES VARIABLY VARYING OR CONTINUING ALONG. Refers to a rotor blade of wind generators with dihedral angles varying discreetly or continuously to increase the aerodynamic and structural efficiencies of the same reducing the induced drag forces and bending moments agents in its structure thus allowing the design and construction of lower weight rotors and higher absorbed wind power when compared to rotors of the same diameter and number of similar blades, but without these dihedral angles.
