Recessed metering standoffs for airfoil baffle

A baffle insert for an internally cooled airfoil, the baffle insert comprising:

• a hollow liner body having a first end and a second end;
• a plurality of cooling holes extending through the hollow liner body to direct cooling air out of the baffle insert;
• and
• a plurality of standoffs extending from an exterior surface of the hollow liner body to maintain a spacing between the baffle insert and an interior surface of an airfoil body;
• wherein the standoffs are recessed such that a height of the standoffs is greater than the spacing.

An internally cooled airfoil comprising:

• an airfoil body shaped to form a leading edge, a trailing edge, a pressure side and a suction side surrounding an internal cooling channel;
• a baffle insert disposed within the internal cooling channel, the baffle insert comprising:
• a hollow liner body having a perimeter shaped to correspond to the shape of the internal cooling channel and to form a cooling air supply duct;
• and
• a plurality of cooling holes extending through the hollow liner body to direct cooling air from the supply duct into the internal cooling channel;
• and
• a plurality of standoffs positioned between the airfoil body and the liner to maintain a spacing between the airfoil body and the liner body;
• wherein the standoffs are recessed such that a height of the standoffs is greater than the spacing.
