Unlocking of a stabilizing member of a folding strut of aircraft landing gear
View Patent ↗The invention relates to landing gear mounted on an aircraft in such a way as to be movable between a stowed position and a deployed position, the landing gear incorporating: a barrel mounted in a hinged way on the aircraft; a folding strut with two arms; a stabilizing member to stabilize the strut in an aligned position, having two rods hinged to each other; a telescopic unlocking member having one end coupled to one of the rods, the telescopic member being selectively activatable to break an alignment of the rods. According to the invention, said rod has an aperture in which the end of the telescopic unlocking member engages and which is arranged in such a way that, when the telescopic member is activated, said end interacts with an end of the aperture to move the associated rod toward a non-aligned position which said rod reaches when the telescopic member reaches an internal stop, the aperture allowing any hinged movement of the rod beyond the non-aligned position.
1. Landing gear mounted on an aircraft in such a way as to be movable between a stowed position and a deployed position, the landing gear comprising:
a barrel mounted in a hinged way on the aircraft to enable the landing gear to move between the stowed position and the deployed position;
a folding strut with two arms hinged to each other, one of which is hinged to the aircraft while the other is hinged to the landing gear, the two arms being in a substantially aligned position at least when the landing gear is in the deployed position;
a stabilizing member to stabilize the strut in an aligned position, having two rods hinged to each other, one of which is hinged to the strut while the other is hinged to the landing gear or to the aircraft, the two rods being pushed back by springs toward an aligned position in which they stabilize the arms of the strut in a substantially aligned position;
a telescopic unlocking member having one end coupled to one of the rods, the telescopic unlocking member being selectively activatable to break an alignment of the rods;
wherein said rod has an aperture in which the end of the telescopic unlocking member engages and which is arranged in such a way that, when the telescopic unlocking member is activated, said end interacts with an end of the aperture to move said rod toward a non-aligned position which said rod reaches when the telescopic member reaches an internal stop, the aperture allowing any hinged movement of said rod beyond the non-aligned position.
2. The landing gear as claimed in claim 1 , in which the aperture extends along an arc of a circle centered on a hinging axis of said rod.
3. The landing gear as claimed in claim 2 in which the aperture has two circular ends.
