Turbine airfoil tip |
摘要 |
<p>Optimized tip performance for turbine airfoils (10) is obtained through a sequenced manufacturing process. The turbine airfoils (10) are assembled into the dovetail slots (22) of a turbine disk (20). The tips (12) of the turbine airfoils (10) assembled in the turbine disk (20) are then measured to determine the turbine airfoils (10) that do not have adequate tip clearance. The tips (12) of those turbine airfoils (10) that do not have adequate tip clearance are then machined to obtain adequate tip clearance. Once all the turbine airfoils (10) have adequate tip clearance, environmental coatings and/or thermal barrier coatings are applied to the blade tips (12). <IMAGE></p> |
