DEVICE TO JOINT TURBOJET ENGINE HINGED JET NOZZLE WITH THE AIRPLANE ENGINE NACELLE Russian patent published in 2008 - IPC F02K1/52 

FIELD: engines and pumps.

SUBSTANCE: device to joint the turbojet engine hinged jet nozzle with the airplane engine nacelle incorporates an annular casing with attached elastic elements tie-linked to the nozzle fixed casing. Elastic elements are in contact with the airplane engine nacelle and moving flaps bearing against the hinged nozzle outer surface. The annular casing and nozzle fixed casing are additionally tied by, at least, three power transmission yoke elements arranged circumferentially between ties. Every yoke element is coupled to the annular casing via a spherical hinge, and to the nozzle fixed casing it is tied by the attached bracket using cylindrical hinges. Cylindrical hinge axes run across the nozzle fixed casing lengthwise axis.

EFFECT: reliable retention of the annular casing relative to the fixed one with a minimum increase in the structure weight and ruling out undesirable strains in the said nozzle assembly.
