Abstract
An annular disk side plate for a gas turbine engine rotor assembly includes an annular plate hub and an annular plate shaft extension extending axially forwardly from the plate hub. A plate web extends radially outwardly from the plate hub and a plate rim extends radially outwardly from the plate web. In the exemplary embodiments of the invention illustrated herein, the plate rim is canted aftwardly from the plate web. One or more annular sealing ridges extend aftwardly from the plate rim. The side plate further includes an anti-rotation means for preventing rotation of the disk side plate relative to the disk such as a circumferential row of radially extending circumferentially spaced apart tabs. Cooling air apertures or holes extend axially through the plate web. A rotor assembly further includes an annular rotor disk comprising a disk hub and an annular disk shaft extension extending axially forward from the disk hub. A disk web extends radially outwardly from the disk hub, a disk rim extends radially outwardly from the disk web, and the disk rim has a forward facing seal face. Rotor blades are mounted in and extend radially outwardly from the disk rim. The annular disk side pla…
