Abstract
A turbine rotor disk fitted with blades having Christmastree-shaped roots, said disk having complementary slots each receiving the root of a blade, wherein at least one stick having a setback holding a spring strip captive is placed in the bottom of each slot of the disk between said bottom and the end face of the root of the corresponding blade. During assembly, the slot of the disk corresponding to the blade that is to be mounted is put in the bottom position and then the root of the blade to be mounted is slid into the slot, after which the sticks, each fitted with its own spring strip are inserted in succession into the empty space between the bottom of the slot and the end of the root of the blade.
