ABSTRACT:
An engine casing is produced by placing a metallic billet between forging dies and rapidly and forcefully closing the dies axially to forge the billet, and includes body structure defining first and second re-entrant body chambers formed at opposite sides of an interior wall, in response to the die closing, and first and second forged body walls extending about the respective first and second chambers, the first wall forged to have a first local thickened section at one side of the first chamber, and the second wall forged to have a second local thickened section at one side of the second wall, the second section offset relative to the first section, the walls and chambers defined by the engine casing; there being a first passage formed axially in the first thickened section and a second passage formed sidewardly into the second thickened section, whereby the passages communicate openly at a nexus at the one side of the second wall; and a cover plate attached to the engine casing to enclose the nexus.
