The present invention relates to a rotor blade of a turbine equipped with a squealer tip which is provided in a pressure surface of the rotor blade extending along the leading edge to a part of a suction surface. The turbine rotor blade, according the present invention, has an effect of reducing pressure loss compared to a turbine rotor blade with a squealer tip formed on the front surface, an effect of additionally reducing pressure loss by alleviating a passage vortex occurred along the suction surface, and an effect of preventing the breakage of the squealer tip caused by heat load by eliminating a heat load area of the squealer in the suction surface. In addition, the turbine rotor blade enhances structural stability by the reduction of the facing sides of the end of the squealer and the casing, and creates a smaller tip gap by facilitating the adjustment of the tip gap through the reduction of the facing sides. The turbine rotor blade enhances a cooling performance by facilitating the discharge of cooling air through a turbine passage during the cooling of the tip floor. |
