GAS TURBINE (VERSIONS) AND SUPPORT FLAME TUBE Russian patent published in 2016 - IPC F23R3/60 

FIELD: machine building.

SUBSTANCE: gas turbine includes a liner, a casing surrounding liner, a hula seal flexibly connected to an aft end of liner and a liner aft support mechanism located downstream from an area where a highest temperature on an outer surface of liner is attained, and upstream to a portion where hula seal is connected to liner, and is configured to movably support liner inside casing. Liner is configured to receive compressed gas and fuel at an upstream end, mixture of compressed gas and fuel being burned in a combustion core area of liner to release hot exhaust gasses at aft end, opposite upstream end. Liner aft end support mechanism includes at least three individual support elements configured to allow a part of individual support elements to move in flow direction relative to at least one of liner or casing. Each of individual support elements includes a spring partially welded to casing surface or liner surface, or both to casing surface and to liner surface.

EFFECT: invention is aimed at reduction of non-uniformity of wear of separate support elements in lock support of liner.
