Abstract:
1. An adaptive brake application and skid detection system for braking of a wheel of an aircraft, comprising: a wheel brake for applying a brake torque to the wheel; wheel velocity signal generating means for producing a wheel velocity signal that is a function of rotational speed of the wheel; wheel velocity comparison means for comparing said wheel velocity signal with a reference velocity signal and for generating a wheel velocity error signal indicative of a difference between said wheel velocity signal and said reference velocity signal; means for adjusting said wheel velocity error signal for producing an anti-skid control signal indicative of a beginning of an initial skid; command brake signal generating means for generating a commanded brake pressure in response to a deceleration command; means for determining a maximum allowed brake pressure based upon a preset brake pressure at which brake torque commences to rise, and a predetermined constant increment of brake pressure; and means for initializing said means for determining a maximum allowable brake pressure to the commanded brake pressure when said wheel velocity error signal becomes greater than a velocity error threshold.
