Method of distributing braking between the brakes of an aircraft
View Patent ↗A method of distribution braking between the brakes of an aircraft. The method includes a first step of estimating a braking force objective and a steering torque objective to be achieved by the brakes of the aircraft. It also includes the steps of defining at least two groups of brakes ( 12, 13 ) and determining, for each group, a braking level that is to be achieved by the group. The braking levels being calculated in such a manner that braking performed in application of the braking levels is, at least under normal operating conditions of the brakes, in compliance with a braking force objective and with a steering torque objective.
1. A method of distribution braking between the brakes of an aircraft, the method comprising the steps of:
estimating a braking force objective ( F ) and a steering torque objective ( C ) to be achieved by the brakes of the aircraft;
defining at least two groups of brakes ( 12 , 13 ); and
determining, for each group, a braking level (Fg, Fd) that is to be achieved by said group, said braking levels being calculated in such a manner that braking performed in application of said braking levels is, at least under normal operating conditions of the brakes, in compliance with the braking force objective and with the steering torque objective.
2. A method according to claim 1 , in which the braking levels are determined that maximize the greatest simultaneous level of satisfaction concerning the braking objective and the steering torque objective.
3. A method according to claim 1 , in which the brakes are distributed between at least a left group ( 12 ) and a right group ( 13 ) that are symmetrical to each other.
4. A method according to claim 3 , in which the steering torque objective ( C ) is specified by a difference between the braking force to be achieved by the left group ( 12 ) and a braking force to be achieved by the right group ( 13 ).
5. A method according to claim 1 , in which the braking force objective ( F ) or the steering torque objective ( C ) are estimated while taking account of action by members of the aircraft ( 3 , 4 , 5 ) other than the brakes and capable of influencing the path followed by the aircraft.
