摘要： A preferred embodiment of the present invention is a gas turbine engine rotor assembly (10) having axially spaced apart forward and aft disks (16, 20) circumferentially disposed about an axis (A). The forward disk (16) has an aftwardly extending annular forward arm (58) and the aft disk (20) has a forwardly extending annular aft arm (60). Forward and aft flanges (64, 68) are located at forward and aft ends (70, 72) of the forward and aft arms (58, 60) respectively. Forward and aft pluralities (76, 78) of aligned forward and aft bolt holes (80, 82) extending axially through the forward and aft flanges (64, 68) respectively. A scalloped annular ring (88) having a plurality of circumferentially spaced apart tabs (83) with spaces (84) therebetween is disposed between the flanges. A plurality of ring bolt holes (86) extend axially through the plurality of circumferentially spaced apart tabs (83) such that corresponding ones of the ring, forward, and aft bolt holes (80, 82) are axially aligned. Forward and aft pluralities (76, 78) of apertures (94, 96) extend axially through the forward and aft flanges (64, 68) and the spaces (84) are in fluid flow communication with corresponding forward and aft ones of the apertures (94). A plurality of bolts (100) are preferably used to attach the forward and aft flanges (64, 68) together and each of the bolts (100) is disposed through corresponding ones of the ring, forward, and aft bolt holes.
