Abstract: An element (14) of a swivelling aircraft landing gear, such as an element of the swivelling, rear or tail gear of a wide-body aircraft, equipped with a swivelling, front or nose gear and a non-swivelling, underwing gear, has a swivelling truck (16) carrying a swivelling, front axle (20) and a swivelling, rear axle (22). The orientation of each of these axles is respectively ensured by two linkages (44-49), which are independent of one another and connected to a non-rotary, fixed support (30) carrying the truck (16), in such a way that the axes (Y1, Y2) of the front (20) and rear (22) axles and the axis of the truck (16) intersect at the instantaneous rotation center of the aircraft.

Abstract: An airbrake located on the wing of an aircraft between a rear spar and a wing flap comprises two panels aligned with the upper surface of the wing when the airbrake is closed. In the open state or fully deployed position, the two panels are contiguous and behave as a single panel. However, in the intermediate states, the panel closest to the flap is deflected more than the other panel, so that a slot is formed between them. This slot makes it possible to significantly decrease turbulence on either side of the airbrake when the latter is used in low deflection flight.
