COMBUSTION CHAMBER (VERSIONS) AND SILENCER FOR GAS TURBINES Russian patent published in 2016 - IPC F02C7/24 

FIELD: machine building.

SUBSTANCE: combustion chamber of the gas turbine including silencer having resonator cavity with output and neck pipe connected by fluid with internal part of the combustion chamber and the resonator cavity, and compensating assembly. Compensating assembly is connected with possibility of rotation with neck pipe, and is inserted between the resonator cavity and the combustion chamber to ensure relative rotation between the combustion chamber and the resonator cavity. The neck pipe is tightly secured at its first end either to the combustion chamber wall, or to inlet of the resonator cavity. The compensating assembly is connected with the possibility of rotation with second end of the neck pipe, and contains ball-like area, created on the second end of the neck pipe, and deepened area, in which the ball-like area is tightly installed to ensure relative rotation between the combustion chamber and the resonator cavity.

EFFECT: invention compensates relative rotation between the combustion chamber and the silencer, in particular resonator cavity, due to difference of thermal expansions.
