Abstract
The present invention relates to a gas turbine blade having a shelf squealer tip, the gas turbine blade including an airfoil-shaped blade housing, and a squealer tip extending from an edge portion of a tip surface that is an end surface of the blade housing, in which the squealer tip is formed only on a part of the edge portion of the tip surface. According to the present invention, it is possible to maximize film-cooling performance on the tip surface and additionally reduce an aerodynamic loss by suppressing high-temperature main flow reattachment and swirl flow generation on the tip surface.
