Abstract
Подвижная лопатка турбины высокого давления турбомашины содержит, по меньшей мере, один охлаждающий контур. Охлаждающий контур образован, по меньшей мере, одной полостью, которая проходит радиально между вершиной и основой лопатки, по меньшей мере, одним впускным отверстием для воздуха на одном радиальном конце полости или пустот для подачи охлаждающего воздуха в охлаждающий контур или контуры с несколькими выпускными щелями. Выпускные щели открыты в полость или полости и выходят на выходную кромку лопатки. Выпускные щели расположены по длине выходной кромки между вершиной и основой лопатки, по сути, перпендикулярно продольной оси лопатки. По меньшей мере, одна выпускная щель, ближайшая к основе перу лопатки, выполнена с наклоном к вершине лопатки под углом от 10° до 30° к оси вращения лопатки.
