Claim 0:
1. A system for maintaining integrally bladed rotors (IBR), the system comprising:
a IBR vibration testing apparatus;
an optical scanner;
a display device;
at least one processor; and
at least one memory including one or more sequences of instructions, the at least one memory and the one or more sequences of instructions configured to, with the at least one processor, cause the system to perform at least the following,
operate the IBR vibration apparatus to accumulate first vibration data of a first IBR to be tested and determining a set of values for a corresponding set of inherent vibratory properties of the first IBR based on the vibration data and a reduced order model for an IBR type to which the first IBR belongs;
operate the optical scanner to measure an initial shape of at least one surface or edge of a first blade of the first IBR;
obtain repair data that indicates a candidate repair to form a restored shape of the at least one surface of the first blade;
predict a change in a value of an inherent blade section vibratory property of the set of inherent vibratory properties of the first IBR based on the restored shape and a single blade finite element model (FEM);
determine an adjusted input for the reduced order model based on the change in the value of the inherent blade section vibratory property;
determine a condition of the first IBR based at least in part on the adjusted input for the reduced order model input to the reduced order model; and
present the condition on the display device.
