Abstract
A vibratory DNA is defined which uniquely characterizes the vibratory state of each integrally bladed disk (IBD) of a fleet and devolves the complex vibrational responses of the IBDs into simple metadata which can be stored in a database and manipulated for various fleet health management purposes. Vibratory DNA can be developed from test apparatus vibration data and can be used to assess the acceptability of a manufacturing or repair process. Changes in vibratory DNA resulting from operation of an IBD in a rotary machine are indicative of operationally induced wear or cracking and can be useful when determining a root cause of failure of an IBD. Vibratory DNA may be used with a reduced order model to perform a virtual engine test of an IBD.
