FIELD: electric power engineering. SUBSTANCE: aim is to increase blade reliability due to improvement of input edge cooling. Cooled blade of gas turbine has hollow vane with longitudinal fin from lock base, butt inner boss with plug. New thing is, that plug is set so, that it rests at fin butt and its diameter is equal at least to minimum width of vane inner canal section located between boss bottom and fin butt. EFFECT: increased blade reliability due to improvement of input edge cooling. 3 dwg |
