<p>The assembly has blades (20) fixed to rotor discs (18) by feet (22) of the blades, and extending outside from the disc. Interblade platforms (30) extend between the adjacent blades, and define an inner profile for fluid flowing through a fan. The adjacent blades form bulge guides (25) on lateral surfaces (20A), where the guides are located outside the disc and limits radial movement of the platforms toward outside. The platforms have C-shaped section, an outer wall (30E), and inner walls (30I) that are located in extension of side walls (30L) and bent towards center of the platforms.</p> |
