FIELD: realization of power plants of flying vehicles; bidirectional conversion of hydraulic energy into electrical energy and vice versa. SUBSTANCE: proposed system provides power supply for flying vehicle equipment; this system is so constructed that power is transferred as required from on-board hydraulic system to electrical system and vice versa. On-board hydraulic system is provided with one or several sources supplying the hydraulic system together with hydraulic consumers connected to it. On-board electrical system is also provided with one or several sources supplying the electrical distributing system together with electrical consumers. General system consists of hydraulic and electrical subsystems which are connected for transmission of rotation by means of reduction gear or shaft. Both subsystems are connected with control unit which is used for control of machines on basis of recorded mode characterizing hydraulic system or electrical distributing system. As a result, corrective adjustment or change of position of mode change-over member built in each subsystem takes place and one of subsystem is placed in operation. EFFECT: reduction of total installed power; enhanced reliability of on-board subsystems. 42 cl, 13 dwg
