Abstract
A rotor stage for a gas turbine engine is provided that includes first and second rotor blades, a disk, and a seal member. Each rotor blade has an airfoil, an attachment section, a neck section, and a platform. The platform has platform inner and outer radial surfaces. The disk has first and second disk slots that are adjacent one another. In an assembled state, the attachment sections are received in the slots. In the assembled state, the platforms of the first and second rotor blades and the outer radial surface of the disk form at least one slot. The seal member includes a central segment and an axial locator tab. In the assembled state, the central segment is disposed for engagement with the first and second rotor blade platforms, and the axial locator tab is disposed in the slot.
