摘要： Aircraft landing gear strut (1) comprising a main part (1a) extending along a main axis (X-X) of the strut and comprising an axle shaft (1b) extending in a plane (P) perpendicular to the main shaft (1a) of the strut, this axle shaft (1b) being designed to support at least one landing gear when (2a, 2b) equipped with brakes (3a, 3b) for braking the wheel, said axle shaft (1b) being made of steel. The axle shaft (1b) bears at least one layer of zinc-nickel alloy coating (C), this zinc-nickel alloy comprising, as a mass percent of the alloy, between 12% and 18% or nickel, at most 0.5% of elements other than nickel and zinc, the rest being zinc.

摘要： Apparatus configured to deform a tubular work piece having a longitudinal axis, the apparatus comprising a support for supporting a tubular work piece to be deformed; rotation means for rotating the tubular work piece about its longitudinal axis; a nozzle for directing a stream of pressurized fluid at the tubular work piece in a direction transverse to the longitudinal axis of the tubular work piece; and means for moving one or both of the tubular work piece and the nozzle relative to one another such that the stream of pressurized fluid can be aimed at a plurality of locations along the tubular work piece; wherein the pressure of the fluid directed at the tubular work piece is great enough to cause deformation of the tubular work piece, but not so great that cutting of the tubular work piece can occur.

摘要： The invention relates to a method for adapting a stop that is adjustable by screwing onto the extremity of a fine tube (1), including the following stages: slipping onto the extremity of the tube (5) a ferrule (10) that is threaded on its external surface and is immobilized on the extremity of the tube by means of a plurality of pins (8) engaged in orifices (7,9) facing towards the ferrule and the tube; screwing onto the ferrule a nut (14) having a first end face (15) acting as a stop in order to preload any element (4, 4) mounted on the tube in front of the ferrule, and a second opposing end face (18) containing forms (25) adapted for it to be driven in rotation by a tool, the nut covering the pins in service.

摘要： An aircraft undercarriage having a sliding rod slidably mounted in a strut-leg, and a scissors linkage (4) having one branch (4a) hinged to the strut-leg or to a turning element of a control for steering the sliding rod mounted to turn in the strut-leg, and one branch (4b) hinged to the sliding rod, the branches being hinged to each other by a pivot pin (12), the undercarriage being fitted with a shimmy-attenuator device (10a, 10b) placed on the pivot pin of the shimmy-attenuator, the attenuator device including threshold resilient return means generating a force returning the branches towards a rest position, and at least damping means generating a damping force when the branches move axially along the pivot pin. The attenuator device comprises two modules (10a, 10b) placed on either side of the scissors linkage in order to co-operate with the pivot pin, each of the modules performing at least one of the damping function and the threshold resilient return function.

摘要： An aircraft landing gear assembly having a main strut and an axle on which wheel and brake assemblies are mounted. An adaptor member is mounted on a mounting pin and arranged to define a brake rod anchor point. The adaptor member is coupled to a part of the landing gear assembly so as to react brake torque and can be formed from a different material than a portion of the main strut.

摘要： The invention relates to a method for connecting in rotation an output member (5) of an electric motor (1) and an element (2) that is to be driven in rotation, comprising the use of at least one fusible pin (11) that links the output member and the element that is to be driven, and that has at least one section that is prone to fail in shear when a torque transmitted by the fusible pin exceeds a predetermined threshold. The method comprises the step of interposing, between the pin and either the output member or the element that is to be driven, at least one elastic member (20) comprising a first travel with a first stiffness followed by a second travel with a second stiffness greater than the first stiffness.

摘要： An aircraft braking system comprising: a first group (Ga) of actuators and a second group (Gb) of actuators. A first control module (105a) is adapted, in a nominal mode, to control the first group, and in a reconfigured mode, to control the first group and the second group. A second control module (105b) is adapted, in a nominal mode, to control the second group, and in a reconfigured mode, to control the first group and the second group. A monitoring unit adapted is adapted to monitor the first control module and the second control module, and to put the first control module into the reconfigured mode of operation when the monitoring unit detects a failure of the second control module, and to put the second control module into the reconfigured mode when the monitoring unit detects a failure of the first control module.
