Abstract

Турбомашина містить вузол дифузор-випрямляч (12), який має нижній фланець (30), який з'єднаний своїм нижнім кінцем з засобом (36) подачі повітря для вентиляції турбіни і обмежує разом з крильчаткою (18) відцентрового компресора кільцеву порожнину (41) для циркуляції повітря вентиляції, відібраного на виході компресора. У турбомашині на засобі подачі (36) розміщений засіб відбору повітря і засіб направляння цього повітря радіально на внутрішню частину поверхні (40) крильчатки.
