Abstract
A turbine blade that is used in a turbine of a gas turbine engine and cooled by cooling air, and includes a cooling channel that is formed within the turbine blade and in which the cooling air flows, plural bottomed recesses that are formed on a blade surface of the turbine blade and of which each downstream-side inner wall is inclined, and an ejection hole that is formed on each bottom of the plural bottomed recesses and communicates with the cooling channel to eject the cooling air. The ejection hole is formed so that a central line of the ejection hole extends along the downstream-side inner wall. The above turbine blade can improve cooling without reducing efficiency.
