Abstract

A turbine blade (1000) includes a blade body (1100) and a squealer tip (1200). The blade body (1100) includes a leading edge (1110), a trailing edge (1120) spaced apart from the leading edge (1110), a suction sidewall (1130) having an outwardly convex shape and connecting one end of the leading edge (1110) to one end of the trailing edge (1120), a pressure sidewall (1140) having an inwardly concave shape and connecting one end of the leading edge (1110) to one end of the trailing edge (1120), and a tip region (1150) on a top surface. The squealer tip 1200 extends upward from the tip region (1150) of the blade body (1100), and includes a first squealer tip (1210) extending upward from the suction sidewall (1130) and a second squealer tip (1220) extending upward from the pressure sidewall (1140). The first squealer tip (1210) and the second squealer tip (1220) extend to different heights. A gas turbine (100) includes a compressor (110) configured to compress air introduced from an external source; a plurality of turbine blades (1000) configured to be rotated by combustion gas generated by the combustor (120) to generate power, wherein each of the turbine blades (1000) comprises the turbine blade (1000).
