Abstract
A gas turbine engine component has an airfoil and a squealer tip. The airfoil has a pressure side and a suction side. The squealer tip is located at one end of the airfoil to engage with an adjacent surface and thereby form a seal. The squealer tip terminates in a squealer tip apex with an arched cross-sectional profile in a plane extending from the pressure side to the suction side of the airfoil. A method for producing an airfoil seal for the gas turbine engine component is also provided.
