    摘要： A resistive and locking system for locking rotation of a shaft, the system comprising: a housing (200) defining an axis AX therethrough, the housing (200) containing: a drive shaft (250) mounted in the housing and extending axially from a bottom end of the housing; a first stage comprising a resistive mechanism (210) provided in the housing around the drive shaft to resist rotation of the drive shaft relative to the housing; a second stage comprising a locking mechanism (230) arranged in the housing above the first stage, the locking mechanism biased axially to frictionally engage with and lock the first stage mechanism to prevent rotation of the drive shaft, the locking mechanism including a magnetic unlocking mechanism configured to remove the frictional engagement with the first stage on application of power to the locking mechanism.

    摘要： Disclosed is an aircraft braking system 100 comprising a plurality of brakes 25, 26, 35, 36, 25', 26', 35', 36' each for braking one of a plurality of aircraft wheels 23, 24, 33, 34 using hydraulic pressure, a first hydraulic pressure supply unit 310, and a second hydraulic pressure supply unit 320 , wherein the first hydraulic pressure supply unit is connected to only a first subset 25 of the plurality of brakes, such that the first hydraulic pressure supply unit can enable only the first subset of the plurality of brakes to provide braking, and wherein the second hydraulic pressure supply unit is connected to only a second subset 26 of the plurality of brakes, the second subset not including any of the brakes of the first subset, such that the second hydraulic pressure supply unit can enable only the second subset of the plurality of brakes to provide braking. Also disclosed is an aircraft landing gear 10, 20, 30 and a method of operating the aircraft braking system 100.

    摘要： A method of taxiing an aircraft may comprise: determining, via a controller (210), whether the aircraft is taxiing with fewer brakes active than a total number of brakes; and modifying, via the controller, a brake pressure supplied to an active brake of the aircraft as a function of pedal deflection in response to determining the aircraft is taxiing with fewer brakes active relative to the total number of brakes.
