Core configuration for casting hollow parts in mating halves

Disclosed is a core for producing halves of cambered hollow articles, such as bonded turbine blades. The core has opposing flanges which differ in thickness, since the opposing contour surfaces are rotated relative to one another, compared to the relationship of the contour surfaces in the interior...

description	Disclosed is a core for producing halves of cambered hollow articles, such as bonded turbine blades. The core has opposing flanges which differ in thickness, since the opposing contour surfaces are rotated relative to one another, compared to the relationship of the contour surfaces in the interior of the hollow article being produced. Thus, the core is made thicker and more sound in the area of high camber where it is otherwise prone to be thin.
