An airfoil (60; 62) for a gas turbine engine, comprising: a pressure side wall radially extending between a root region and a tip region; a suction side wall that is circumferentially spaced apart from the pressure side wall, radially extending between the root region and the tip region, and joined to the pressure side wall at a leading edge and a trailing edge that is axially spaced apart from the leading edge a tip surface that is disposed proximate the tip region and is extending between the pressure side wall, the suction side wall, the leading edge, and the trailing edge; a gusset extending between the pressure side wall and the suction side wall; and a first pocket surface formed in the tip region and extending between the leading edge, the pressure side wall, the suction side wall, and the gusset, the first pocket surface, the pressure side wall, the suction side wall, and the gusset define a squealer pocket; characterized in that: within the squealer pocket, an inner surface of the suction side wall is angled towards the pressure side wall in a direction that extends from the first pocket surface towards the tip surface; and in that the airfoil further comprises a first suction side hybrid skin core cavity that radially extends from the root region towards the tip region and through the first pocket surface and is disposed adjacent to the suction side wall and the gusset, and spaced from the pressure side wall; and a first pressure side hybrid skin core cavity spaced apart from the first suction side hybrid skin core cavity, the first pressure side hybrid skin core cavity radially extending from the root region towards the tip region and radially extending through the first pocket surface and being disposed adjacent to the leading edge, the pressure side wall and the gusset, and spaced from the suction side wall. a pressure side wall radially extending between a root region and a tip region; a suction side wall that is circumferentially spaced apart from the pressure side wall, radially extending between the root region and the tip region, and joined to the pressure side wall at a leading edge and a trailing edge that is axially spaced apart from the leading edge a tip surface that is disposed proximate the tip region and is extending between the pressure side wall, the suction side wall, the leading edge, and the trailing edge; a gusset extending between the pressure side wall and the suction side wall; and a first pocket surface formed in the tip region and extending between the leading edge, the pressure side wall, the suction side wall, and the gusset, the first pocket surface, the pressure side wall, the suction side wall, and the gusset define a squealer pocket; characterized in that: within the squealer pocket, an inner surface of the suction side wall is angled towards the pressure side wall in a direction that extends from the first pocket surface towards the tip surface; and in that the airfoil further comprises a first suction side hybrid skin core cavity that radially extends from the root region towards the tip region and through the first pocket surface and is disposed adjacent to the suction side wall and the gusset, and spaced from the pressure side wall; and a first pressure side hybrid skin core cavity spaced apart from the first suction side hybrid skin core cavity, the first pressure side hybrid skin core cavity radially extending from the root region towards the tip region and radially extending through the first pocket surface and being disposed adjacent to the leading edge, the pressure side wall and the gusset, and spaced from the suction side wall. within the squealer pocket, an inner surface of the suction side wall is angled towards the pressure side wall in a direction that extends from the first pocket surface towards the tip surface; and in that the airfoil further comprises a first suction side hybrid skin core cavity that radially extends from the root region towards the tip region and through the first pocket surface and is disposed adjacent to the suction side wall and the gusset, and spaced from the pressure side wall; and a first pressure side hybrid skin core cavity spaced apart from the first suction side hybrid skin core cavity, the first pressure side hybrid skin core cavity radially extending from the root region towards the tip region and radially extending through the first pocket surface and being disposed adjacent to the leading edge, the pressure side wall and the gusset, and spaced from the suction side wall.
