FIELD: high-power electrohydraulic servo drives for actuating flying vehicle controls by signals of electric remote flight control system. ^ SUBSTANCE: proposed servo drive has twin power hydraulic cylinder at position feedback, servo drive with twin two-system power hydraulic distributor and control cylinders of servo drive, as well as twin two-system hydraulic distributor of servo drive. Power hydraulic distributor and control hydraulic cylinders of servo drive are made in form of single cylinder with stepped plunger which is additionally provided with beads and steps forming cavities for controllable hydraulic cylinders of servo drive at ends of plunger for one hydraulic system and on steps of plunger for other hydraulic system. ^ EFFECT: reduction of power of linear electric motor, its overall dimensions and mass; improved static and dynamic accuracy of servo drive. ^ 2 cl, 3 dwg |
