Turbine blade having a plurality of configurations chamfered squealer tip formed from members and convection cooling holes

摘要

It is available in repair system, and a squealer tip formed from the pressure-side weld rib (12) and the suction-side outer weld rib (14) (10), a pressure-side weld ribs and the suction-side outer weld ribs, the turbine The extending from the tip of the blade (18) (16) radially outward is present in the pressure side and the suction side welded members separated by an intermediate chord members (21) (17, 19) discloses a squealer tip . The pressure side and suction side outer weld ribs, respectively, are positioned along the pressure side of the turbine blade (20) and suction side (22). The pressure side outer welding rib has a chamfered pressure side (24) having film cooling holes (26) having an exhaust outlet positioned therein. The pressure side and suction side welded member is configured to hold the intermediate chord members in position over extended sides.
