Abstract

Disclosed is a single-cast, thin wall structure capable of withstanding impinging gases at temperatures of 4300.degree. F. and higher, and method of making the same. Using a bleed line of the instant invention allows for a decreasing metal pressure with respect to time which prevents any damage to the thin outer mold wall.
