Abstract

sistema de comando de pás com passo variável para uma turbomáquina, que compreende uma fileira anular de pás com passo variável que se estendem em torno de um eixo (a) e que compreendem cada uma delas uma lâmina ligada em sua extremidade radialmente externa a um pivô (20) que define um eixo substancialmente radial de rotação da pá e que é ligado por uma alavanca (34) a meios de comando (40a, 40b) que se estendem em torno do dito eixo, caracterizado pelo fato de que os ditos meios de comando compreendem primeiros elos (40a) portados pelos ditos pivôs e segundos elos (40b) que se estendem entre os ditos primeiros elos, os ditos primeiros e segundos elos se estendendo substancialmente em uma mesma circunferência em torno do dito eixo e que são ligados uns aos outros e a meios de acionamento (56).
