Abstract

resumo “pá e ângulo diédrico de pá” a presente invenção refere-se a uma pá de compressor definida em cada um dos pontos de superfície da mesma por um ângulo de curvatura e por um ângulo diédrico que compreende: uma raiz, uma ponta, sendo que a distância entre a raiz e a ponta, medida ao longo de um eixo geométrico referido como o eixo geométrico radial perpendicular a um eixo geométrico de rotação do compressor, é referida como uma altura radial (h), uma zona entre a raiz e a ponta da qual uma primeira porção tem um ângulo diédrico de borda de ataque estritamente positivo e uma segunda porção tem um ângulo diédrico de borda de ataque estritamente negativo, sendo que a zona de ângulo diédrico máximo é, ao longo do dito eixo geométrico radial, entre r = 0,25 h e r = 0,7 h.
