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.

Abstract: An example diffuser assembly includes a diffuser case, an annular ring, and a retaining tab that is mounted to the annular ring and has an end that engages an inner wall of the diffuser case. The engagement between the second end and the inner wall locks the retaining tab and limits movement of the annular ring along a central longitudinal axis of the diffuser case. Another example diffuser assembly includes a diffuser case, an annular ring, and a snap ring. The snap ring is situated in an annular groove of an inner wall of the diffuser case, and restricts movement of the annular ring along a central longitudinal axis of the diffuser case. A retaining tab is affixed to either the annular ring or the diffuser case, and has an end retaining the annular ring in the annular groove.

Abstract: A ring has a ring body with a central portion surrounding an axis and extending to first and second opposing ends separated by a split. The central portion has a first axial thickness. At least one retaining feature is formed on the ring body, the at least one retaining feature having a second axial thickness greater than the first axial thickness. An assembly and a gas turbine engine are also disclosed.

Abstract: Aspects of the disclosure are directed to systems and methods for receiving operating state parameters associated with an operative state of an aircraft, determining a clearance value between a first structure of the engine and a second structure of the engine, where the clearance value is determined based on the operating state parameters and a passive clearance model that includes a specification of an uncertainty in the clearance value, determining that the clearance value deviates from a clearance target in an amount that is greater than a threshold, and engaging an active clearance control (ACC) mechanism based on the deviation.
