Abstract:
A one-piece rotor spool for a gas turbine engine extending along the axis of the engine is disclosed. The spool includes an upstream portion and a downstream portion that are radially offset relative to one another. The radially outer downstream portion includes a plurality of housings for rotor blades formed in the outer surface of the radially outer downstream portion. The radially inner upstream portion includes an attachment mechanism designed to interact with a rotor ring in order to prevent a tangential movement of the rotor ring relative to the radially inner upstream portion.
