摘要
A turbine blade includes a cooling channel through which cooling air is passed, and a swirl portion provided at an entrance of the cooling channel so as to form a swirl flow in the cooling air. The turbine blade may increase cooling performance of a root unit, improve the stiffness of the root unit, and increase the internal heat transfer efficiency of a blade unit.
