TURBINE BLADE WITH CELL STRUCTURE

摘要

The present invention relates to a blade of a gas turbine with a plurality of cooling flow paths, where cooled air flows into and circulates by the blade connected to the cooling flow paths for the cooled air to collide with an internal wall of the blade and be cooled. The blade of the present invention comprises: a cooling tube installed in a cooling flow path to cool a leading edge side of the blade from among the plurality of cooling flow paths, with a plurality of cooling holes formed to spray and collide with the cooled air; and a cellular structure formed in between the cooling tube and an internal wall of the blade by a combination of a plurality of unit cells (C).
