DEVICE FOR ARTICULATING THE OUTER SURFACE OF THE ROTARY JET NOZZLE OF THE TURBOJET ENGINE AND THE AIRCRAFT ENGINE NACELLE Russian patent published in 2018 - IPC F02K1/80 F02K1/52 B64D29/00 

FIELD: engines and pumps.

SUBSTANCE: invention relates to the aircraft engine construction, in particular to the design of the rotary nozzles of turbojet engines at the articulation point of the pivoting device of the nozzle with the engine nacelle of the aircraft. Device for articulating the outer surface of the rotary jet nozzle of the turbojet engine and the aircraft nacelle contains an annular body with elastic elements fixed thereon. Device is equipped with a coupling mechanism made in the form of a cable with a turn-buckle, brackets for securing the coupling mechanism to the surface of the elastic elements. Annular body is made of at least two parts connected to each other with the possibility of detachment and rigid attachment to the aircraft engine nacelle. Elastic elements are installed with the possibility of contact with adjacent elastic elements, are tied together and adjoin the outer surface of the rotary part of the jet nozzle. In this case, at least two elastic elements with a turn-buckle are installed at the place of the connector of the parts of the annular body and are made removable.

EFFECT: invention provides a simplification of the process and shortens the assembly/disassembly time of the articulation device of the outer surface of the rotary jet nozzle of the turbojet engine and the aircraft engine nacelle, providing mobility and sufficient tightness at the articulation site.
