GAS TURBINE ENGINE DISTRIBUTOR, GAS TURBINE ENGINE TURBINE AND GAS TURBINE ENGINE Russian patent published in 2014 - IPC F01D9/02 F01D11/02 

FIELD: engines and pumps.

SUBSTANCE: gas turbine engine distributor comprises inner and outer circular platforms connected by radial blades. Inner platform comprises circular elements made of abradable material arranged at sheet sectors that make a ring of L-, S- or C-shape-cross-section inside inner platform. Inner edges of every sheet sector is soldered or welded to inner platform while outer edges are secured to abradable element or at sheet ring secured at abradable element. Distributor inner platform is composed of cylindrical baffle divided in sections. Inner platform sectors are molded elements and support sealing plates soldered or welded to platform sector by one edge and, by another, edge staying in sliding contact with adjacent sector of the platform level with sheet sectors supporting abradable elements. Other inventions of the set relate to gas turbine engine turbine with above described distributor and to gas turbine engine incorporating said turbine.

EFFECT: decreased weight and thermal inertia means retaining abradable elements.
