Axial retention system for a bladed rotor with multiple blade types

摘要

A bladed rotor includes a blade lock mountable to a rotor hub adjacent to a multiple of blade slots. The blade lock includes at least one interface feature adjacent to a first of the multiple of blade slots. A first rotor blade includes a blade feature which interfaces with the interface feature to permit the first rotor blade to be axially mounted within the first of the multiple of blade slots but not within a remainder of the multiple of blade slots.

1. A bladed rotor comprising:
a rotor hub which defines a multiple of blade slots; a blade lock mountable to said rotor hub, said blade lock includes first and second interface features circumferentially arranged with respect to a first and a second of said multiple of blade slots, respectively; and a first rotor blade configured to be axially mounted within said first of said multiple blade slots, said first rotor blade includes a first blade feature that is complimentary with said first interface feature such that said first rotor blade can only fully be received into said first of said multiple of blade slots but not fully received into a remainder of said multiple of blade slots that are not circumferentially arranged with respect to said first interface feature; a second rotor blade configured to be axially mounted within said second of said multiple blade slots, said second rotor blade includes a second blade feature that is complimentary with said second interface feature such that said second rotor blade can only fully be received into said second of said multiple of blade slots but not fully received into a remainder of said multiple of blade slots that are not circumferentially arranged with respect to said second interface feature.
