ROBUST TURBINE BLADES

摘要

Robust turbine blade designs that minimize damage to turbine blades during a tip rub event, guard against further tip recession, and improve the resiliency of turbine blades 24 are provided. This may be achieved through various blade tip 12 designs, such as a recessed tip 28 or a protruding tip 98. It may also be achieved by providing the blade tip, shroud, or both with an environmental barrier coating (EBC) 22 having an abradable or abrasive layer.
