Abstract
Фиксированное стяжное кольцо расположено вокруг газового окна (14) прохождения горячих газов газовой турбины. Стяжное кольцо окружено фиксированной кольцевой полостью (2), которая представляет собой кольцевую камеру охлаждения (26), в которую выходит по крайней мере одно впускное отверстие (28), которое проходит через кольцевую полость. Стяжное кольцо (4) состоит из множества кольцевых сегментов (16), каждый из которых содержит внутреннюю систему верхнего охлаждения (А) и внутреннюю систему нижнего охлаждения (В). Внутренняя система нижнего охлаждения (В) остается независимой от вышеназванной системы верхнего охлаждения (А) и радиально смещена относительно названной системы верхнего охлаждения (А).
