UNIT OF GAS TURBINE ENGINE, MODULE OF GAS TURBINE ENGINE AND GAS TURBINE ENGINE Russian patent published in 2013 - IPC F02C7/20 F01D25/24 

FIELD: engines and pumps.

SUBSTANCE: device contains a plug meant for connection with the first assembly; also it contains a connecting element meant for connection with the second assembly. The connecting element contains through holes located between the first and the second eye lugs of the plug which contain the first and the second holes of the plug correspondingly. In addition it contains axial system of shift passing through the first hole of the plug, the second hole of the plug and a through hole; the system contains a threaded end interacting with the nut system. The nut is borne against the second eye lug of the plug. From the side, opposite to the threaded end, axial system contains extended section passing through the first hole of the plug and forming a collar located between the first and the second eye lugs of the plug. Connecting element located at a distance from the first eye lug of the plug is clamped on both sides between the collar and the second eye lug of the plug and is designed as a rack. The first and the second assemblies are annular and concentric and are rigidly interconnected by means of multiple connecting devices distant from each other in circular direction. The first annular assembly is located radial inside relative to the second annular assembly. The plug of each connecting device provided to the first annular assembly is installed so that on top view longitudinal axis of the plug is bent at the same angle of installation relative to the axis of the first and the second annular assemblies. The first and the second assemblies restrict annular space between them forming a section of the primary channel for gases passing in gas turbine engine. Also objects of invention are a module of gas turbine engine containing the unit described above and a gas turbine engine with this module.

EFFECT: invention allows reducing overall dimensions of the parts of the gas turbine engine.
