Abstract

resumo “rotor de turbomáquina com meio de retenção axial das pás” a invenção tem como objeto um rotor de turbomáquina, tal como uma ventoinha de turborreator de fluxo múltiplo, que compreende um disco (4) com alvéolos substancialmente axiais e com seção em cauda de andorinha no aro e pás (6) montadas individualmente nos 5 alvéolos, um calço axial (143) sendo disposto entre o pé das pás e o fundo dos alvéolos e uma trava transversal (144) assegurando o bloqueio axial a montante das pás no alvéolo das mesmas, a trava sendo guiada em entalhes radiais dispostos nos flancos dos alvéolos e se apoiando radialmente sobre o calço. o rotor é caracterizado pelo fato de que o calço axial (143) é imobilizado na direção de a montante estando para isso em batente contra uma 10 peça anular transversal (145) solidária do disco (4).
