Claim 12:
13. A method for maintaining integrally bladed rotors (IBR), the method comprising:
operating a 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;
operating an optical scanner to measure an initial shape of at least one surface or edge of a first blade of the first IBR;
obtaining repair data that indicates a candidate repair to form a restored shape of the at least one surface of the first blade;
determining automatically on a processor 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);
determining an adjusted input for the reduced order model based on the change in the value of the inherent blade section vibratory property;
determining automatically on the processor 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
presenting on a display device the condition.
