A rotor of an aircraft turbomachine having a main axis A, which includes modifying the critical speed of the rotor, depending on whether the rotational speed of the rotor is lower or higher than a predefined rotational speed, including a component that is capable of occupying a first state or a second state depending on whether the rotational speed of the rotor is lower or higher than the predefined rotational speed, each state of the component corresponding to a critical speed of the rotor, and driving the component to one or the other of the two states thereof, depending on the rotational speed of the rotor, wherein modifying the critical speed of the rotor further includes a component that engages with the drive means and is capable of being deformed elastically between one or the other of two stable forms, each of which corresponds to a state of the component. |
