• a rotor disk provided at an outer periphery thereof with a plurality of slots, each slot being formed between two adjacent disk teeth and extending axially between front and rear faces of the rotor disk;
• a plurality of blades, each of the blades having a respective root mounted in a respective slot of the rotor disk;
• and
• at least one pin mounted in the rotor disk to pass through the roots of at least two adjacent blades and extending between and up to the front and rear faces of the rotor disk so as to attach the blades to the rotor disk,
• wherein the blades are made of composite material and the rotor disk is metallic.
