Abstract
A rotor disk for a gas turbine engine having an axis of rotation and an axial centerline is provided which includes a rim, forward and aft hubs, and forward and aft webs. The forward web extends between the rim and the forward hub, and the aft web extends between the rim and the aft hub. The forward and aft hubs are separated. Each web is skewed from the axial centerline. A circumferentially extending cavity is formed between the webs and the hubs.
Claims11
A rotor disk for a gas turbine engine having an axis of rotation and an axial centerline, said rotor disk comprising:
- a rim;
- a first hub having a first bore centered on the axis of rotation;
- a first web having a first interior surface, said first web extending between said rim and said first hub, and wherein said first web intersects a central potion of said first hub such that portions of said first hub extend away from said first web in both axial directions, and said first web is skewed from the axial centerline;
- a second hub, having a second bore centered on the axis of rotation, wherein said first and second hubs are spaced apart;
- and
- a second web having a second interior surface, said second web extending between said rim and said second hub, and wherein said second web intersects a central portion of said second hub such that portions of said second hub extend away from said second web in both axial directions, and said second web is skewed from the axial centerline;
- wherein a circumferentially extending cavity is formed between said web interior surfaces and said hubs.
