摘要： The adaptive brake application and initial skid detection system allows rapid brake application and prevents deep initial skids. Brake pressure is compared with a predetermined threshold brake pressure. Wheel velocity error signals are also generated to indicated the difference between the wheel velocity and a reference velocity signal. A pressure bias modulator integrator responsive to brake pressure signals adjusts the wheel velocity error signals to provide an anti-skid control signal. The pressure bias modulator integrator can also be initialized to the value of the measured brake pressure when the wheel velocity error signals indicate the beginning of a skid. Brake pressure difference signals are generated to indicate the difference between brake pressure and a commanded brake pressure, and an adjusted brake pressure error signal is generated in response to the brake pressure difference signals.

摘要： The braking control system provides dual redundant control of hydraulically operated wheel braking for an aircraft. A primary hydraulic system provides hydraulic power for normal operation of the plurality of wheel brakes, and a secondary hydraulic system provides hydraulic power for alternate operation of the plurality of wheel brakes. A control unit is provided for controlling brake pressure communicated to the wheel brakes through the primary and secondary hydraulic systems, and a monitor channel is operatively connected to the primary hydraulic system for detecting faults in the primary and secondary hydraulic systems and for selecting between the primary and secondary hydraulic systems for providing braking pressure. The monitor channel detects occurrence of loss of pressure in the primary hydraulic system, if any brake has unwanted pressure applied, and if a fault is detected on the primary or secondary channels that affects more than one wheel brake on each landing gear. The primary hydraulic system comprises at least one primary hydraulic fluid control channel and at least one secondary hydraulic fluid control channel, the primary and secondary fluid channels being redundant and partitioned among the plurality of wheel brakes so that even if both the primary and secondary channels fail to apply pressure, braking will be lost to only a portion of the wheel brakes and the loss will be in a symmetrical pattern, and the secondary hydraulic system comprises at least one primary hydraulic fluid control channel and at least one secondary hydraulic fluid control channel.
