Turbine engine blades with drillable film cooling holes

摘要

A turbine engine component (10), such as a blade or a vane, is provided by the present invention. The turbine engine component has a pressure side (14) and a suction side (16). Each of the pressure and suction sides (14,16) has an external wall (22,26) and an internal wall (24,28). A first set of fluid passageways (60) is located on the pressure side (14) between the external wall (22) and the internal wall (24). A second set of fluid passageways (62) is located on the suction side (16) between the external wall (26) and the internal wall (28). Each of the fluid passageways (60,62) in the first set and in the second set has a wavy configuration. The turbine engine component (10) may also have one or more wavy trailing edge cooling passageways (106) for cooling a trailing edge portion (20) of the component.
