Abstract

　Contact-type disc brakes used in aircraft axle brakes have the disadvantage that the discs and brake pads wear out each time the brake is applied. The authors have therefore been researching and developing a new non-contact type eddy current aircraft brake. This study investigated the characteristics of the eddy current brake when a composite material disc is used to improve the brake torque in a three-phase AC excitation. As a result, the value of the brake torque of the composite material disc was obtained 53% higher than that of a Cu disc.
