Abstract
Лопатка (10) газовой турбины турбомашины имеет контур охлаждения, который содержит, по меньшей мере, одну полость (26) удлиненой формы, которая расположена в радиальном направлении между хвостовиком лопатки и ее торцом, и по меньшей мере, одно отверстие впуска, которое расположено в нижнем радиальном конце полости и предназначено для подачи в нее охлаждающего воздуха. По меньшей мере, одна из стенок (26а, 26b) полости (26) охлаждения оборудована углублениями (30), которые обеспечивают возмущение потока охлаждающего воздуха в указанной полости и увеличение теплообмена.
