Abstract

A gas turbine engine (20) is provided that includes an axial centerline (32), a compressor section (24), a combustor (26), a turbine section (28), and engine shaft, and a shaft retention system (54). The engine shaft is engaged with the compressor and turbine sections. The engine shaft has an aft end and axially extends along the engine axial centerline. The shaft retention system includes a shaft retainer cap (56) and a retainer piston (58). The shaft retainer cap is attached to the aft end of the engine shaft. The retainer piston is mounted for axial translation. The shaft retention system is disposable in an engaged configuration wherein the retainer piston is coupled with the shaft retainer cap, and in a disengaged configuration wherein the retainer piston is disengaged with the shaft retainer cap.
