摘要:
An internally cooled airfoil (10) comprises an airfoil body (12), a baffle (18) and a plurality of standoffs (34, 36, 56, 74, 76, 78). The airfoil body is shaped to form leading (20) and trailing (26) edges, and pressure (22) and suction (24) sides surrounding an internal cooling channel (30). The baffle is disposed within the internal cooling channel and comprises a liner body having a perimeter shaped to correspond to the shape of the internal cooling channel and to form a cooling air supply duct. The baffle includes a plurality of cooling holes (28) extending through the liner body to direct cooling air from the supply duct into the internal cooling channel. The standoffs maintain minimum spacing between the liner body and the airfoil body. The standoffs are recessed into a surface of either the baffle or the airfoil body. In another embodiment, the standoffs are elongated to meter flow between the liner body and the airfoil body.
