FIELD: mechanical engineering; gas-turbine engines.
SUBSTANCE: invention relates to turbine blade with improved cooling characteristics. Turbine blade contains profiled part with some span and at least one cooling channel in, profiled part passing from root section of profiled part to its tip section. Group if turbulence activation means is made in at least one cooling channel. Said means have changing value of ratio of pitch between adjacent turbulence activation means to height of each of said turbulence activation means along said span.
EFFECT: improved degree of balance cooling.
