摘要：
An increase in the initial gas temperature to 900 degree C before the turbine of the GTN-25 gas pumping unit has necessitated the cooling of the stator blades of the high-pressure turbine. The hollow blade air cooling system is described. Tests at gas temperatures of 800-1050 degree C and cooling air temperatures of 120 to 410 degree C were carried out and results are presented. It is shown that even at 1000 degree C gas temperatures the cooled blade temperatures do not exceed 870 degree C, which is acceptable with corrosion-resistant coatings.
