Brake system for aircraft

Abstract

Abstract PURPOSE:To compensate a torque gain for a change and to effect constantly accurate generation of brake torque by a method wherein the opening of a valve mechanism to regulate a pressure fed to a hydraulic brake is corrected so that detecting brake torque coincides with target brake torque. CONSTITUTION:When a pilot pedals a brake valve 3, target brake torque is computed by a torque controller 5 from a brake indication amount according to a pedaling angle, and a corresponding opening signal is outputted to a pressure control servo valve 4. After an oil pressure from an oil pressure source is regulated, it is fed to brake 2 to brake wheels 1. In this case, brake torque is detected by means of a torque sensor 6, and the opening of a pressure control servo valve 4 is corrected according to a deviation between brake torque and target brake torque. When, from an output from a rotation speed sensor 7, the generation of a skid is detected by an antiskid controller 8, the opening of a pressure control servo valve 4 is further corrected.
