An actuating device for moving a mobile cap of a thrust reverser, which includes: an actuator having a first element, such as a screw, and a second element, such as a nut, collaborating with the first element in such a way that turning the first element causes the second element to move in a translational movement. A locking piece is rotationally mobile between a locked position in which the locking piece prevents the first element from turning, and an unlocked position in which the locking piece allows the first element to turn. An unlocking piece is rotationally mobile between an active position in which the unlocking piece urges the locking piece towards the unlocked position and a passive position in which the unlocking piece allows the locking piece to return to the locked position.

Flight control device for an aircraft

A coupling comprising a driven part and a driving part that is connected by a safety pin so as to drive the driven part together with the driving part in a travel direction, one of the parts having a male portion engaged in a female portion of the other part, the male and female portions respectively having a first guide surface and a second guide surface facing each other in such a manner that, in the event of the pin breaking, the driving part is capable of moving relative to the driven part in the travel direction, the pin extending perpendicularly to said direction through corresponding holes made in the male and female portions, the coupling being characterized in that the hole made in the male portion opens out in the bottom of a setback in the second guide surface.

Coupling with securing pin

An actuator for hinging a first element to a second element about a first pivot axis (A), the actuator comprising a motor-drive device, a first mounting plate () connected to a body () of the motor-drive device, a second mounting plate () connected to the second element, the second mounting plate being mounted in the first mounting plate in order to pivot about the first axis, and a bush () mounted in the second mounting plate to pivot about a second axis (A) perpendicular to the first axis. The motor-drive device has an outlet shaft () pivotable about a third axis (A) perpendicular to the first axis and intersecting the first axis, and it is extended by a pin () that is pivotally received in the bush and that has a central axis (A) intersecting the first axis and the third axis, and forming an acute angle with the third axis. An aircraft guidance assembly including such an actuator.

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.

The invention relates to a device comprising a lever associated with a stand carrying a rocker connected to the stand by a pivot connection about a first axis, the lever being connected to the rocker by a pivot connection about a second axis, a first transmission shaft with a first connection mechanism connecting the lever to the first transmission shaft, and a second transmission shaft with a second connection mechanism connecting the control lever to the second shaft. The first shaft and the first connection mechanism being connected by a pivot connection about a fifth axis that is inclined relative to the first axis and to the third axis, and the second shaft and the second connection mechanism are connected by a pivot connection about a sixth axis that is inclined relative to the second axis and to the fourth axis.

The invention relates to an actuation device () for moving a movable cover of a thrust reverser. Said actuation device includes: &#x2014;an actuator including a first element (), such as a screw, and a second element (), such as a nut, that engages with the first element such that rotation of the first element causes translation of the second element; &#x2014;a locking portion () rotatable between a locked position, wherein the locking portion prevents the first element () from rotating, and an unlocked position, wherein the locking portion () allows the first element () to rotate; and &#x2014;an inhibiting part () that is translatable between a first position, wherein the inhibiting part () allows the locking portion () to rotate, and a second position, wherein the inhibiting part () prevents the locking portion () from rotating into the locked position.
