HIGH-PRESSURE TURBINE STATOR Russian patent published in 2014 - IPC F02C7/12 F01D25/14 

FIELD: machine building.

SUBSTANCE: turbine stator comprises distributor support and resilient flange front end face and diaphragm, all being arranged on combustion chamber inner housing. Diaphragm outer radial rib is bolted to distributor support. Diaphragm inner radial rib is bolted to inner and outer cellular flanges and to resilient flange rear end face. Diaphragm central part between outer and inner ribs is radially resilient and cylindrical in cross-section as well as bulged towards cellular flange. L-like-cross-section flange is arranged between resilient flange and distributor support to make a slotted ring chamber. Said circular chamber outlet is communicated with combustion chamber air space while, via distributor support channel, with the stator air space composed by distributor support, resilient flange and diaphragm. Ratio between spacing between diaphragm bolt joints and radius of inner cylindrical surface makes 3…4.

EFFECT: higher reliability.
