Embodiment Construction

[0016] For an aircraft comprising two main landing gears, left and right, each comprising two brake wheels (1 and 2 for the left and 3 and 4 for the right), we can respectively inferred:

[0017] C 1 = E 1 E 1 + E 2 · C g

[0018] C 2 = E 2 E 1 + E 2 · C g

[0019] above for the left undercarriage; and

[0020] C 3 = E 3 ...

Abstract

A method for distributing braking energy between a group of braked wheels 1 . . . p and fitted to N undercarriages of an aircraft, each of the braked wheels comprising a brake furnished with a stack of discs to which a load is selectively applied so as to generate a torque for braking the wheel. Each brake is equipped with means for measuring a thickness of the stack of discs, and in which: the setting C j = E j E 1 + ... + E p . N . C is assigned as individual setting of braking to be generated by brake j. Here, p is the number of wheels concerned, C is the general setting of braking to be developed by the braked wheels of the same undercarriage, Ej is the thickness of the stack of discs of the brake of wheel j, and Cj the individual braking setting for wheel j. Each brake is controlled according to the individual braking setting thus determined.

Description

technical field [0001] The invention relates to a method for distributing a braking torque between braking wheels fitted to at least one landing gear of an aircraft. Background technique [0002] On some aircraft, an uneven distribution of the braking energy dissipated by the brakes can be observed despite the same brake settings being applied, which will lead to uneven heating and wear of the brake disc pack. [0003] Additionally, some brakes may reach or exceed critical temperature thresholds, which will force the airline that used the aircraft to hold off until those brakes fall back into temperature range before starting a new rotation. And that waiting time means lost revenue for the airline. Contents of the invention [0004] The object of the present invention is to propose a method for distributing braking energy between the brakes, whereby significant heating of certain brakes is avoided to the greatest extent. [0005] For this purpose, the invention proposes ...
