Abstract: An airfoil includes a squealer tip at an outer radial end of the airfoil. A squealer tip pocket of the squealer tip has a convex side and a concave side, and a tip plate. A divider extends across the tip plate from the concave side to the convex side to divide the squealer tip pocket into a first pocket and a second pocket. At least one cooling passage through the tip plate in the second pocket provides fluid communication through the tip plate from an interior of the airfoil to the second pocket. The first pocket is fluidically disconnected from the interior of the airfoil.
