Multiple disc brakes uses stators & rotors to brake?

How do they work?

    $\begingroup$ The overall answer would be the stack of discs is pressed by the pressure plate using a fluid and friction slows the rotors. This is explained on the original site. Could you clarify which part you don't understand, Is this the friction part, the fluid part?... $\endgroup$ – mins Jan 29 '17 at 11:37
  • $\begingroup$ Exactly as mins said, this works just the same as a single disc brake, just with more discs. $\endgroup$ – Rory Alsop Jan 29 '17 at 11:55

    $\begingroup$ I am voting NOT to close this question as I believe the theory and function of aircraft mechanical systems to be on topic here. However, if you have an opinion on the quality of this question—for example it is "especially useful" or it displays "no-effort-expended"—I would encourage you to indicate this with an up or down vote. $\endgroup$ – J Walters Jan 29 '17 at 15:08

A disc brake works in a very similar way to the brakes on a bicycle. The wheel rim on the bicycle can be considered to be similar to one of the discs in an aircraft brake unit. When the brake is applied on a bicycle the callipers squeeze the brake pads against the rim, the friction slows the rim/wheel. A typical aircraft brake pack consists of several discs which are keyed to the inside rim of the wheel and rotate with the wheel, there are also several discs which are keyed to the stationary axle, these discs are interleaved and form a pack. The rotating discs in the wheel rim are squeezed against the stationary discs on the axle by hydraulic pressure using several pistons spaced around the discs, (like several calipers might be spaced around the wheel rim of a bicycle if they were required). The resultant friction slows the wheel and consequently the aircraft. Incidentally the friction energy is converted to heat during the braking.
