FIELD: engines and pumps.
SUBSTANCE: proposed device comprises at least one air circulation circular channel made along circumference about turbine stator annular housing to feed air thereto to vary its temperature. At least a part of tubular air distributor is arranged around air circulation channel or channels. There is also, one tube to feed air into aforesaid tubular air distributor and at least one air duct communicated with aforesaid air distributor and air circulation channel (channels). Said air duct is furnished with air duct air pressure limiter.
EFFECT: possibility to equalise airflows to limit thermal nonuniformity of turbine stator.
