    摘要: The invention relates to an aircraft undercarriage comprising: a strut (1) for connecting to the aircraft, a slide rod (3) slidably engaged in leaktight manner in the strut via the bottom opening, which rod carries at least one wheel at its bottom end, a diaphragm (7) carried by a support (8) attached to the top wall of the strut to cooperate in leaktight manner with an inside wall of the slide rod so as to define a first chamber (C1) under the diaphragm inside the rod and completely filled with hydraulic fluid, and a second chamber (C2) above the diaphragm and partially filled with hydraulic fluid, a throttle needle (10) secured to the slide rod and penetrating into a calibrated orifice (12) in the diaphragm so as to define a calibrated fluid passage between the first and second chambers, and angular connection means for imposing an angular position on the slide rod relative to the strut. According to the invention, the undercarriage includes at least one vane (20) fastened to the end of the throttle needle in order to extend inside a portion of the second chamber that is filled with hydraulic fluid.

    摘要: A method of managing the braking of an aircraft, the aircraft having a plurality of wheels R1, . . . , R12, each fitted with a brake F1, . . . , F12 adapted to generate a braking force in response to brake pedals 5 being depressed. The management method comprising the steps of (1) distributing the wheels fitted with respective brakes in at least two distinct groups G1, G2, G3, G′1, G′2, G′3; (2) allocating respective braking relationships to each of the groups of wheels for determining how braking force varies as a function of the depression of the brake pedals; and (3) acting at predetermined intervals to permutate the allocation of the relationships to the groups in application of a predefined permutation relationship. The method also includes a step of modifying the permutation relationship in response to the occurrence of a predetermined event.

    摘要: A method of actuating undercarriage latching boxes and associated hatch latching boxes of an aircraft in an emergency mode, the latching boxes having at least one feed port and at least one unlatching member that is operable when the port is fed with fluid under pressure, the aircraft also being provided with a hydraulic braking circuit. The method includes connecting at least one tapping circuit to the braking circuit of the aircraft in association with an isolation valve that is kept, in a normal mode, in an isolation state and that can be controlled to be placed in an open state in which at least some of the feed ports of the latching boxes are fed by the tapping circuit connected to the braking circuit.

    摘要: Measurement equipment for measuring the inflation pressure of a tire of a vehicle wheel 1. The equipment comprises a body 16 defining an internal volume, a communication orifice 19 for putting the inside volume of the body 16 into communication with an inflation chamber situated between a rim 2 and a tire of the wheel and containing an inflation gas and an indicator member 25 slidably mounted in the body 16 so as to define a gastight separation between a first chamber 26 containing a given quantity of a reference gas and a second chamber 27 into which the communication orifice 19 leads. As a result, the indicator member 25 is subjected to opposing pressures that exist in each of the chambers. A position-identification device 30 is operative to identify the position of the indicator member in the body.
