HYDRAULIC SYSTEM FOR THE AIRBUS 380The Airbus A380 hydraulic system consists of two hydraulic systems (green and yellow). A third hydraulic system used on previous Airbus aircraft is replaced by an electrohydraulic system made of a combination of electrohydraulic actuators (EHAs) and electrical backup hydraulic actuators (EBHAs). For the first time in civil aircraft history the A380 will use a high-pressure 5000-psi hydraulic system. The fluid remains a standard phosphate-ester type as used on most civil aircraft. The A380 hydraulic system integrates a total of eight Vickers PV3-300-31 (EDPs). The pumps are pressure-compensated, variable displacement type, and deliver 42 gpm at 3775 rpm. Their displacement is 47 ml/rev. The EDPs have a disengagement clutch, a feature not currentl…
