Beschreibung
Zusammenfassung:	FIELD: construction of flying vehicles; control systems of unmanned flying vehicles. ^ SUBSTANCE: proposed electrohydraulic servo drive includes hydraulic cylinder with actuating rod, spool valve and linear electric drive with rod for motion of spool valve. Actuating rod of hydraulic cylinder and rod of linear electric drive are equipped with position sensors whose output signals are connected to inputs of linear electric drive controller. Linear electric drive is provided with second output of rod on whose side spring-loaded drive rods fitted with stops are located for separate contact with this rod and with actuating rod of hydraulic cylinder; free ends of drive rods are connected with edges of link whose center part is connected with tie rod through hinge. Spool valve is spring-loaded and is provided with stop. Rod of linear electric drive may be separately engageable with spring-loaded spool valve and with drive rod. ^ EFFECT: reduced mass and overall dimensions of power supply source of control system and enhanced linearity of its characteristics. ^ 2 dwg
