FIELD: engines and pumps.
SUBSTANCE: invention relates to gas turbines. This structural element is provided with at least one coolant guide channel terminating at unstructured surface. Surface located nearby channel mouth has at least one groove-like recess separated from said mouth by web for efficient decrease in concentration of strain caused by the channel as compared with strain in the case of groove-like recess absence. Said web features minimum wall thickness while channel has minimum mouth diameter. Wall minimum depth-to-diameter ratio varies from 0.05 to 3, preferably, from 0.05 to 2.
EFFECT: longer life of structural element.
