<p>PURPOSE: A turbine impeller with a blade is provided to avoid the generation of a hot-spot formed inside a squealer tip or around the blade, thereby reducing thermal damages of the blade and obtaining high efficiency. CONSTITUTION: A turbine impeller with a blade comprises a rotor(130), a blade(110), and squealer tips(121,122). The blade is formed in the rotor. The squealer tips are formed in an end portion of the blade. One or more penetration units(121_1,122_1) penetrating through the squealer tips are formed in the squealer tips.</p> |
