Zusammenfassung:A bladed rotor disk assembly includes a plurality of circumferentially spaced apart blade root slots 218 extending through a rotor disk 202 at an angle to the disk axial direction. Each slot has a radially inwardly facing load reaction surface 224A, 224B along each side thereof extending continuously over less than the full the length of the slot 218 in contact with a corresponding radially outwardly facing load reaction surface 222A, 222B of a blade root 206 disposed within the slot 218. This eliminates highly concentrated reaction loads adjacent the ends of the slot and results in a more uniform load distribution over the remaining smaller reaction surface area, reducing maximum stresses.
