ABSTRACT:
A cooled blade of a small gas turbine engine can enhance cooling performance without increasing the amount of cooling air in a simple configuration. A cooled turbine blade is provided with a cooling passageway12formed inside thereof, making the cooling air flow therein. Film-cooling holes13penetrate from an inner wall surface111to an external wall surface112and form a cooling film. An impingement cooling member2has a multiple number of small holes21ejecting the cooling air. A gap t made by the inner wall surface111and the impingement cooling member2has a sealing portion14mounted thereon which divides the gap in a blade chord direction.
