ABSTRACT:
A fan assembly includes a plurality of discrete platforms disposed between adjacent rotor blades extending radially outwardly from a rotor disk. Each platform includes forward and aft axially spaced apart ends, and radially upper and lower spaced apart surfaces extending between the ends. Forward and aft retainer rings capture the platform to the disk with a predetermined clearance therebetween for allowing the platform to move radially upwardly under centrifugal force for retention by the retainer rings, while also allowing the platform to move radially inwardly under a radially inwardly directed impact load on the platform, which impact load is channeled through the platform lower surface at both the forward and aft ends into the rotor disk.
