Abstract
Disclosed is a coupling system comprising joints configured to friction lock under compressive pressure via tapered teeth for joining rotating components, which may be rotating components of a gas turbine, or other engine. The coupling system provides the alignment orientation for the joined components, and eliminates the need for extraneous fasteners, bolts, interference fits and/or keying arrangements. The coupling system further enables material optimization by allowing for use of different materials throughout different engine sections, depending on the operating parameters.
