Abstract: The present invention relates to a force application device for a control stick of an aircraft comprising a shaft and a control lever configured to rotate the shaft about a first axis, the device comprising: a magnetic brake comprising a braking part configured to be connected to the shaft, and a volume containing a rheological fluid in contact with the braking part, of variable shear resistance as a function of a magnetic field applied to the rheological fluid, a force feedback motor configured to exert a resistive force opposing the rotation of the shaft about the first axis, a motor power source, a movable magnetic element biased towards a position close to the magnetic brake, and distancing means configured to maintain the movable magnetic element in a position away from the magnetic brake, when such distancing means are powered by the power source.

Abstract: The invention relates to a flight control device for an aircraft, including a connection lever, mechanical means for limiting an angular stroke of the connection lever, first means for generating force feedback on the connection lever about said pivot axis, second means for generating force feedback on the connection lever, which means are arranged in parallel with the first means, at least one element selected from the second means and the connection lever comprising mechanical means for connecting them together temporarily, which means are arranged to be active when the connection lever is moved beyond a predetermined angular position in the angular range so that the second means are connected to the connection lever.

Abstract: The invention relates to a fly-by-wire system which comprises: three-stage piloting control, each stage including a control computer suitable for determining the positions of the stick, and a monitoring computer capable of verifying all the pre-determined positions of the stick; three-stage control-surface position calculation, each stage including a control computer suitable for calculating the control-surface positions from encoded positions of the stick, and a monitoring computer capable of verifying all the calculated control-surface positions; a single unidirectional communication link connecting the control computer of the first piloting control stage to the control computer of the first control-surface position calculation stage; a single unidirectional communication link connecting the control computer of the second piloting control stage to the control computer of the second control-surface position calculation stage; and a single unidirectional communication link connecting the control computer of t

Abstract: The invention concerns an actuating device (1) for moving a mobile cover of a thrust reverser, comprising: an actuator (5) comprising a first element (10), such as a screw, and a second element (12), such as a nut, mounted mobile device relative to the first element (10) such that the rotation of the first element (10) results in a translational movement of the second element (12) relative to the first element (10), and a locking device (31) comprising a rotating part (34) linked in rotation with the first element (10), and a locking part (35) that is mobile relative to the rotating part (34) between a locked position in which the locking part (35) is engaged with the rotating part (34) to prevent the first element (10) from rotating and an unlocked position in which the locking part (35) is disengaged from the rotating part to allow the rotation of the first element (10), and an electromagnet (39) for moving the locking part (35) to the unlocked position.
