A bladed rotor disk assembly includes a plurality of circumferentially spaced apart blade root slots 118 extending through a rotor disk 102 at an angle 82 to the disk axial direction. Each slot has a radially inwardly facing load reaction surface 124A, 124B along each side thereof extending continuously over less than the full the length of the slot 106 in contact with a corresponding radially outwardly facing load reaction surface 122A, 122B of a blade root 106 disposed within the slot 118. 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. <IMAGE> <IMAGE> |
