FIELD: engines and pumps.
SUBSTANCE: turbine stator comprises outer case to support nearing props with fairing (7), cooled nozzle blades (14) with lower flanges (15) arranged downstream of gas flow (5). Inner radial rib (8) of every fairing (7) is arranged in U-like seal ring (9) fitted at cylindrical flange (11) of the support. U-like seal ring (9) has outer and inner C-cross-section ledges (12) and (13) directed towards nozzle blades (14). Said outer and inner C-cross-section ledges (12) and (13) make pin-hole joint with inner ring (16) fitted radially at lower flanges (15) of blades (14). Shell (22) of inner ring (16) has channels (23) for proportioned feed of cooling air into lower-pressure chamber (20).
EFFECT: higher reliability of gas turbine engine bearing support.
