DRIVE ON BASE OF SYNCHRONIZED HYDRAULIC CYLINDERS, REACTION NOZZLE OF TURBOJET ENGINE (VERSIONS) AND TURBOJET ENGINE Russian patent published in 2007 - IPC F02K1/15 

FIELD: aircraft industry; turbojet engines.

SUBSTANCE: proposed turbojet engine includes reaction nozzle with variable exit section and orientation determined by position of movable flaps, and drive on base of synchronized hydraulic cylinders. Drive contains hydraulic control system, drive hydraulic cylinder, at least one driven hydraulic cylinder and mechanical transfer device. Drive hydraulic cylinder has cylinder and piston forming two spaces in cylinder connected with hydraulic control system. Driven hydraulic cylinder contains cylinder and piston determining two spaces in cylinder at least first space of which is coupled with output of distributor. Distributor is connected with hydraulic control system, and it contains control member whose position defines pressure in first space of driven hydraulic cylinder. Mechanical transfer device service to transmit displacement of piston of drive hydraulic cylinder to control member of distributor connected with driven hydraulic cylinder. Distributor is connected with driven hydraulic cylinder so that piston of driven hydraulic cylinder automatically follows piston of drive hydraulic cylinder by position command received from control member of distributor connected with driven hydraulic cylinder.

EFFECT: provision of simultaneous displacement of hydraulic cylinder rods, reduced mass of drive.
