GAS TURBINE EXPANSION COMPENSATOR (VERSIONS) AND METHOD OF PROVIDING FLUID FLOWING FROM EXHAUST CHANNEL Russian patent published in 2012 - IPC F01D25/00 F01D11/00 

FIELD: machine building.

SUBSTANCE: expansion compensator is arranged between turbine channel and exhaust channel comprises flange attached to turbine channel, flexible element and multiple plates attached to exhaust channel to extend to said flange. Flexible element is arranged between turbine channel flange and exhaust channel and attached thereto. Multiple plates and flange are space apart, clearance there between being narrower in turbine channel hot state. In compliance with another version, multiple plates have multiples holes and are bolted to exhaust channels. Said holes have diameter larger than that of bolts to allow for thermal expansion of said multiple plates. To allow fluids to flow from exhaust channel, multiple plates are arranged at exhaust channel with clearance between turbine channel and said multiple plates. Flexible element is attached to turbine channel nearby said clearance and to exhaust channel. Turbine channel is heated to widen it in direction of multiple plates to narrow said clearance.

EFFECT: smooth transition between turbine channel and exhaust channel, ease of production.
