Method for manufacturing a split engine casing from a cylinder

摘要

The method of fabricating a jet engine casing into two removable halves is disclosed. The method includes turning a cylindrical blank to obtain the radial structural ribs, diametrically slotting axially the outer diameter to receive two mating flanges and boring the inside diameter to remove sufficient material to expose the inner edge of the mating flanges whereby the casing is split along the axial axis.
