<p>The rotor has a disc (11) with recess (16) at its outer periphery and blade attached to the disc. The blade has a base engaged and retained in the recess, and a spacer (22) of composite material is defined between the base and a bottom of recess. An axial retention flange (26) is fixed upstream of the disc with respect to emerging ends of the disc. The disc and the flange are formed to define teeth (34, 48) and (44, 50), respectively. An axial clearance (J) is defined between the teeth (34, 48) of disc to permit an annular web (46) to deform before the teeth comes in contact.</p> |
