More Information
Summary:The invention relates to an aeronautical thruster (10) having a longitudinal axis (X) and comprising a hub (12) and at least two annular rows of non-streamlined blades (18) including an upstream annular row (14) and a downstream annular row (16) spaced apart from one another along said longitudinal axis (X), the upstream annular row (14) being rotatable about the longitudinal axis (X), and the downstream annular row (16) comprising a series of blades including a first blade (18a) and a second blade (18b) each extending in a radial direction from the hub (12) so as to define a radial dimension between the hub (12) and a radially outer end of the corresponding blade (18a, 18b), characterised in that the radial dimension of the first blade (18a) is greater than the radial dimension of the second blade (18b). Propulseur aéronautique (10) d'axe longitudinal (X) comprenant un moyeu (12) et au moins deux rangées annulaires de pales (18) non carénées comprenant une rangée annulaire amont (14) et une rangée annulaire aval (16) espacées l'une de l'autre suivant ledit axe longitudinal (X), la rangée annulaire amont (14) étant mobile en rotation autour de l'axe 5 longitudinal (X), ladite rangée annulaire aval (16) comprenant une série de pales incluant une première pale (18a) et une deuxième pale (18b) s'étendant chacune selon une direction radiale depuis le moyeu (12) de sorte à définir une dimension radiale entre ledit moyeu (12) et une extrémité radialement externe de la pale (18a; 18b) respective, caractérisé en ce que la dimension radiale de la première pale (18a) est supérieure à la dimension radiale de 10 la deuxième pale (18b).
