Abstract
An airfoil for a gas turbine engine includes pressure and suction walls spaced apart from one another and joined at leading and trailing edges to provide an airfoil having an exterior surface that extends in a radial direction to a tip. A camber line at the tip extends from the leading edge to the trailing edge. Pressure and suction side shelves are arranged in the exterior surface on opposing sides of the camber line respectively in the pressure and suction side walls. A plateau is proud of and separates the pressure and suction side shelves. The plateau is arranged along the camber line and extends to the leading edge.

An airfoil for a gas turbine engine comprising:
- pressure and suction walls spaced apart from one another and joined at leading and trailing edges to provide an airfoil having an exterior surface that extends in a radial direction to a tip, a camber line at the tip extending from the leading edge to the trailing edge;
- pressure and suction side shelves arranged in the exterior surface on opposing sides of the camber line respectively in the pressure and suction side walls;
- and
- a plateau proud of and separating the pressure and suction side shelves, the plateau arranged along the camber line and extending to the leading edge.
A gas turbine engine comprising:
- a compressor and turbine section mounted to a shaft, and a combustor arranged between the compressor and turbine section;
- and
- an airfoil in one of the compressor and turbine sections, the airfoil includes pressure and suction walls spaced apart from one another and joined at leading and trailing edges to provide an airfoil having an exterior surface that extends in a radial direction to a tip, a camber line at the tip extending from the leading edge to the trailing edge;
- pressure and suction side shelves arranged in the exterior surface on opposing sides of the camber line respectively in the pressure and suction side walls;
- and
- a plateau proud of and separating the pressure and suction side shelves, the plateau arranged along the camber line and extending to the leading edge.
