Automatic aircraft braking system including wheelspeed responsive control apparatus

摘要

This invention relates to an aircraft braking system which applies and regulates brake pressures automatically upon touchdown to achieve a pre-selected airplane deceleration level. Wheelspeed information signals are processed through wheelspeed logic circuits to provide an input to automatic brake control circuits having further logic circuits which, when satisfied by the presence of other signals, cause further automatic brake control circuits including a ramp generator circuit to generate control signals which are coupled in parallel with the anti-skid system to control the anti-skid valve driving current below skid levels so that braking pressure is increased at a controlled rate to achieve the above-mentioned pre-selected airplane deceleration level.
