REGULATED SUPERSONIC NOZZLE OF TURBO-JET ENGINE Russian patent published in 2015 - IPC F02K1/12 

FIELD: engines and pumps.

SUBSTANCE: regulated supersonic nozzle of turbo-jet engine contains casing, hingedly connected to it subsonic and external louvers connected with supersonic louvers, and louvers drive and synchronisation gear. The synchronisation gear is made as levers installed in circumferential direction between the subsonic louvers and hingedly connected tie-rods with two adjacent subsonic louvers, and brackets installed on the levers with possibility of rotation, and hingedly connected by additional tie-rods with two adjacent external louvers. Axle of the hinge joint of the tie-rod and lever is located along the lever rotation plane, axle of tie-rod and subsonic louver connection - along its rotation plane. Axle of the hinge joint of the additional tie-rod and bracket is located along the bracket rotation plane, axle of additional tie-rod and external louver connection - along its rotation plane.

EFFECT: invention excludes break of the tie-rod axles near the eye rings, thus reducing their deformation during the nozzle operation, and excludes negative effect of the axial gaps of the hinge joints on the synchronous movement of subsonic and external louvers.
