Embodiment Construction
[0026] Such as figure 1 and figure 2 As shown, the rotor disk 2 is provided with a number of grooves or "slots" 4 along its outer edge, which form cavities, each of which can receive a blade root 16 of a blade 14, around which the blade root 16 is lined. Pad 20. The blade root 16 and the fan disk 2 are made of, for example, a titanium alloy.
[0027] It should be noted that these assemblies are also provided with a spacer (not shown) between the blade root 16 and the bottom of the slot 4 .
[0028] When the wheel disk 2 rotates, the blade 14 bears the centrifugal force, and the support surface 16A on the blade root 16 will be tightly pressed on the support surface 22A of the wheel disk 2 . In the example described, the support surfaces 16A form the wings of the blade root 16 , while the support surfaces 22A form the underside of the wheel lip 22 extending on both sides of the outer opening of each slot 4 .
[0029] The liner 20 includes two side walls 20A intended to come...
