ABSTRACT:
A brake device for the rotor of a helicopter, the device associating a mechanism having a disk and a manual control for main braking of the rotor, and a mechanism for secondary braking of the rotor under strong wind. The secondary braking device includes a secondary lever hinged to the body and capable of being actuated against secondary return elements to drive a bearing finger against a main lever of the main brake mechanism and cause the jaws of the mechanism to move correspondingly towards each other so that the secondary lever actuates the main lever in order to amplify the clamping forces applied to the disk by the jaws in comparison with the forces they exert when driven by the main lever alone.
