GAS TURBINE SEALING ASSEMBLY Russian patent published in 2018 - IPC F01D11/08 F01D11/12 F01D25/24 

FIELD: engines and pumps.

SUBSTANCE: gas turbine sealing assembly comprises an annular body with annular cover mounted thereon (2) with holes (3), an above-rotor insert located between them (8) is segmental and made of ceramic composite or ceramic material. The assembly also comprises a composite screen (15) located above the segments of the above-rotor insert (8), and a spring (13) located between the composite screen (15) and the annular body (1). The composite screen (15) is mounted for overlapping the gaps between the segments (9) of the above-rotor insert (8). There are sealing elements (11) installed in the gaps (10) between the segments (9) of the above-rotor insert (8).

EFFECT: high operational reliability of the gas turbine sealing assembly with ceramic composites or the ceramic above-rotor inserts due to reliable fixation of segments of the above-rotor insert on the annular body, improved cooling efficiency of the sealing assembly.
