FIELD: gas-turbine engines.
SUBSTANCE: invention relates to ventilating unit of gas-turbine engine stator ring. Proposed unit contains branched tubes including supply tubes, distributors and manifolds arranged close to ring and provided with holes through which gas is force-fed in direction of ring. Manifolds are formed by pairs of semienvelopes containing end face part and rim enclosing end face part. Pairs of semienvelopes are connected along rims. Distributors contain bushing 5 forming spacers between manifolds. Bushings are provided with end parts adapted for mating with holes in side parts of end face parts.
EFFECT: facilitated manufacture and mounting of ventilating unit of gas-turbine engine stator ring.
