Abstract

resumo “conjunto de pás de passo variável e uma turbomáquina” trata-se de uma palheta de passo variável que compreende: - uma pluralidade de pás de hélice (2), sendo que cada uma é de passo variável de acordo com um eixo geométrico rotacional de pá (a1) e cada uma tem uma raiz (201), - uma pluralidade de eixos de conexão de rotor (6), cada eixo tem um pé (602) e uma cabeça (601), a raiz (201) de cada pá é montada na cabeça (601) de um eixo de conexão de rotor por meio de um pivô (8) de modo tal que permita cada pá (2) rotacione de acordo com o eixo geométrico rotacional de pá (a1), em que cada pá (2) tem um passo de pá, de modo que um eixo geométrico rotacional de pá (a-i) da mesma é inclinado em relação a um eixo geométrico radial (a2) que passa através do pés (602) do eixo correspondente.
