Abstract
A fly-by-wire control mechanism for a rotorcraft, the mechanism comprising a stick (1) hinged to tilt in multiple directions on a support (2), detector means (6) for detecting the tilting position of the stick (1) and generating electrical signals (7), and force feedback means providing the pilot with a sensation of forces (12) opposing tilting of the stick (1). The stick (1) includes a rod (13) having its distal end held in fixed manner in the support (2), while providing a movable mount for the stick (1) on the support (2). Causing the stick (1) to tilt leads to flexing of the rod (13) from its anchor zone (16) in the support (2), with the resistance of the rod (13) to flexing deformation serving to develop the opposing forces (12) and also being measured in order to generate the electrical signals (7).
