On the low pressure compressor rotor individual disks are used in stages 0 and 1. Stages 2 through 4 of the low pressure compressor rotor are an integral spool. Stages 0 and 1 blades have been modified to include squealer tips. Stage 0 blades are individually retained in the axial dovetail slots of the disk by a one-piece blade retainer. Stages 1 through 4 blades are retained in circumferencial slots and stages 2 through 4 spool. The blade retention feature allow individual blade replacement. Blades on stages 0 through 3 can be removed without removing the rotor. As the compressor rotates, the blades load centrifugally and become tight fitting.
