TURBINE BLADE WITH CHAMFERED SQUEALER TIP FORMED FROM MULTIPLE COMPONENTS AND CONVECTIVE COOLING HOLES

摘要

A squealer tip (10) usable in repair systems and formed from a pressure side outer weld rib (12) and a suction side outer weld rib (14) extending radially outward from a tip (16) of the turbine blade (18) and resting upon pressure side and suction side weld members (17, 19) separated by a mid-chord member (21) is disclosed. The pressure and suction side outer weld ribs may be positioned along the pressure side (20) and the suction side (22) of the turbine blade, respectively. The pressure side outer weld rib may include a chamfered pressure side (24) with film cooling holes (26) having exhaust outlets positioned therein. The pressure and suction side weld members may be configured to retain the mid-chord member in position with over extending side surfaces.
