Patent ID: 8201895

Claim:
A power supply architecture for powering aircraft brakes for an aircraft having at least two undercarriages, each having a certain number of wheels (L 1 , L 2 ; R 1 , R 2 ), each of the wheels being fitted with a brake having a certain number of electromechanical braking actuators ( 1 , 2 , 3 , 4 ), wherein the architecture includes at least first, second, third, and fourth power supply units, the first and third power supply units (B 1 , B 3 ) being powered by a first power supply source (AC 1 ), the second and fourth power supply units (B 2 , B 4 ) being powered by a second power supply source (AC 2 ), the wheels on each of the undercarriages being grouped into first and second complementary groups (L 1 ; R 1 ; L 2 ; R 2 ) and the power supply units powering complementary groups of braking actuators in each of the groups of wheels as follows: the first power supply unit (B 1 ) powers a group of actuators ( 1 , 2 ) of the first group of wheels (L 1 ) of the first undercarriage, and a group of actuators ( 1 , 2 ) of the first group of wheels (R 1 ) of the second undercarriage; the second power supply unit (B 2 ) powers a complementary group of actuators ( 3 , 4 ) of the first group of wheels (L 1 ) of the first undercarriage, and a group of actuators ( 1 , 2 ) of the second group of wheels (R 2 ) of the second undercarriage; the third power supply unit (B 3 ) powers a group of actuators ( 1 , 2 ) of the second group of wheels (L 2 ) of the first undercarriage, and a complementary group of actuators ( 3 , 4 ) of the second group of wheels (R 2 ) of the second undercarriage; and the fourth power supply unit (B 4 ) powers a complementary group of actuators ( 3 , 4 ) of the second group of wheels (L 2 ) of the first undercarriage, and a complementary group of actuators ( 3 , 4 ) of the first group of wheels (R 1 ) of the second undercarriage.
