Abstract
A rotor disk for a fan in a turbomachine is disclosed. The disk includes in its perimeter a plurality of essentially axial grooves for the installation and retention of vane roots having hooks at their downstream ends, and deformable regions formed by cavities being situated at the downstream end of the grooves in attachment flanges for inter-vane platforms to absorb the stresses between the disk and the vane roots.
