I have a hydraulically actuated aircraft brake system. Each main landing gear are equipped with brake disk hydraulically operated. The actuation is realized independently for each wheels by means of the correspondent control valve which controls pressure delivery to the brakes. Each brake control valve is connected to each pedal brake. When the pedal brake is depressed, the control valve will open and deliver a variable pressure to the brake adjusted by the pedal angel. The problem is the Brake is too responsive. When the pedal is depressed slightly, the aircraft suddenly stop.
What is the main problem? Is it the hydraulic flow to the brake disk too high?
Can I install a "restrictor valve" from the brake valve to disk to restrict the flow and make the brake smoother? if so, how can i determine the size of the restrictor valve?
or the pressure to disk brake is too high?
the function of accumulator is for emergency
