ANTISKID BRAKE CONTROL FOR AIRCRAFT ABSTRACT OF THE DISCLOSURE An antiskid brake control for aircraft is presented wherein sensitive deceleration detectors are connected to wheel speed transducers for presenting output signals when the deceleration rate of a wheel exceeds a threshold level. The output of the deceleration detector is passed to a valve driver for releasing brake pressure. The deceleration detec- tor output is also passed to a modulator which causes its voltage level to increase and further reduce brake pressure. The modulator acts as a memory circuit to keep the average brake pressure near the skid level and also provides for a controlled reapplication of brake pressure following the re- lease. A constant current discharge circuit is connected to the modulator to provide a liner discharge of the modulator capacitor. A fast recovery circuit is interconnected between the deceleration detector and modulator to rapidly discharge the modulator capacitor in the event that no outputs from the deceleration detector have been sensed for a predetermined period of time. The control system; includes gain circuitry to provide for at least three distinct system gains: a low gain when the outputs of the deceleration detector indicate that only incipient skids have been experienced; a higher gain when the output of the deceleration detector is indica- tive of deep or severe skids; and a third lower gain when the output of the modulator is indicative of a runway having a low mu. Also provided as a portion of the invention is touch- down protection circuitry which holds brake pressure off when the aircraft is in the air and for a fixed time period fol- lowing touchdown, unless the wheels have spun- up past a predetermined rotational speed. Such circuitry further controls reapplication of the antiskid system to the braking effort following a bounce of the braked wheels.
